jaxx.compiler.tags

Class DefaultObjectHandler

java.lang.Object

jaxx.compiler.tags.DefaultObjectHandler

All Implemented Interfaces:

TagHandler

Direct Known Subclasses:

BeanValidatorHandler, DefaultComponentHandler

public class DefaultObjectHandler
extends Object
implements TagHandler

Default handler for class tags. Class tags are tags which represent instances of Java classes, such as <JButton label='Close'/>. DefaultObjectHandler provides support for attributes and events which adhere to JavaBeans naming conventions as well as basic JAXX features like the id attribute and data binding by means of curly braces.

Throughout this class, the word "member" refers to the name of a field or method (e.g. "getDocument") and the word "property" refers to the JavaBeans-style simple name of a property (e.g. "document").

Constructor Detail

DefaultObjectHandler

public DefaultObjectHandler(ClassDescriptor beanClass)

Creates a new DefaultObjectHandler which provides support for the specified class. The class is not actually introspected until the compileFirstPass(org.w3c.dom.Element, jaxx.compiler.JAXXCompiler) method is invoked.

Parameters:

beanClass - the class which this handler supports

Method Detail

getEventInfo

public DefaultObjectHandler.ProxyEventInfo getEventInfo(String memberName)

init

protected void init()
             throws IntrospectionException

Performs introspection on the beanClass and stores the results.

Throws:

IntrospectionException - if any pb

getBeanClass

public ClassDescriptor getBeanClass()

Returns:

the class which this DefaultObjectHandler supports.

getJAXXBeanInfo

public JAXXBeanInfo getJAXXBeanInfo()

Returns:

the JAXXBeanInfo for the class which this DefaultObjectHandler supports.

getJAXXBeanInfo

public static JAXXBeanInfo getJAXXBeanInfo(ClassDescriptor beanClass)
                                    throws IntrospectionException

Returns the JAXXBeanInfo for the specified class.

Parameters:

beanClass - the bean class for which to retrieve JAXXBeanInfo

Returns:

the class' JAXXBeanInfo

Throws:

getPropertyType

public ClassDescriptor getPropertyType(CompiledObject object,
                              String propertyName,
                              JAXXCompiler compiler)

Returns the type of the named property. This is the return type of the property's get method; for instance JLabel's text property is a String.

Parameters:

object - the object being compiled

propertyName - the simple JavaBeans-style name of the property

compiler - the current JAXXCompiler

Returns:

the property's type

Throws:

CompilerException - if the type cannot be determined

isMemberBound

public boolean isMemberBound(String name)
                      throws UnsupportedAttributeException

Parameters:

name - name of the property

Returns:

true if the named member is bound (fires PropertyChangeEvent when modified). Members are either fields (represented by the simple name of the field) or get/is methods (represented by the simple name of the method, not the simplified JavaBeans-style name). Methods which are not actually bound in their native class, but for which proxy events have been configured (such as JTextField.getText, return true.

Throws:

UnsupportedAttributeException - if attribute is not supported

getEventClass

public static ClassDescriptor getEventClass(ClassDescriptor listenerClass)

configureProxyEventInfo

protected void configureProxyEventInfo()

Configures the event handling for members which do not fire PropertyChangeEvent when modified. The default implementation does nothing. Subclasses should override this method to call addProxyEventInfo for each member which requires special handling.

addProxyEventInfo

public void addProxyEventInfo(String memberName,
                     Class<?> listenerClass)

Configures a proxy event handler which fires PropertyChangeEvents when a non-bound member is updated. This is necessary for all fields (which cannot be bound) and for methods that are not bound property get methods. The proxy event handler will attach the specified kind of listener to the class and fire a PropertyChangeEvent whenever the listener receives any kind of event.

Even though this method can theoretically be applied to fields (in addition to methods), it would be an unusual situation in which that would actually work -- as fields cannot fire events when modified, it would be difficult to have a listener that was always notified when a field value changed.

Parameters:

memberName - the name of the field or method being proxied

listenerClass - the type of listener which receives events when the field or method is updated

addProxyEventInfo

public void addProxyEventInfo(String memberName,
                     Class<?> listenerClass,
                     String modelName)

Configures a proxy event handler which fires PropertyChangeEvents when a non-bound member is updated. This is necessary for all fields (which cannot be bound) and for methods that are not bound property get methods. This variant attaches a listener to a property of the object (such as model) and not the object itself, which is useful when there is a model that is the "real" container of the information. The proxy event handler will attach the specified kind of listener to the property's value (retrieved using the property's get method) and fire a PropertyChangeEvent whenever the listener receives any kind of event.

If the property is itself bound (typically the case with models), any updates to the property's value will cause the listener to be removed from the old property value and reattached to the new property value, as well as cause a PropertyChangeEvent to be fired.

Even though this method can theoretically be applied to fields (in addition to methods), it would be an unusual situation in which that would actually work -- as fields cannot fire events when modified, it would be difficult to have a listener that was always notified when a field value changed.

Parameters:

memberName - the name of the field or method being proxied

listenerClass - the type of listener which receives events when the field or method is updated

modelName - the JavaBeans-style name of the model property

addProxyEventInfo

public void addProxyEventInfo(String memberName,
                     Class<?> listenerClass,
                     String modelName,
                     String addMethod,
                     String removeMethod)

addProxyEventInfo

public void addProxyEventInfo(String memberName,
                     ClassDescriptor listenerClass,
                     String modelName,
                     String addMethod,
                     String removeMethod)

Configures a proxy event handler which fires PropertyChangeEvents when a non-bound member is updated. This is necessary for all fields (which cannot be bound) and for methods that are not bound property get methods. This variant attaches a listener to a property of the object (such as model) and not the object itself, which is useful when there is a model that is the "real" container of the information. The proxy event handler will attach the specified kind of listener to the property's value (retrieved using the property's get method) and fire a PropertyChangeEvent whenever the listener receives any kind of event.

If the property is itself bound (typically the case with models), any updates to the property's value will cause the listener to be removed from the old property value and reattached to the new property value, as well as cause a PropertyChangeEvent to be fired.

This variant of addProxyEventInfo allows the names of the methods that add and remove the event listener to be specified, in cases where the names are not simply add<listenerClassName> and remove<listenerClassName>.

Even though this method can theoretically be applied to fields (in addition to methods), it would be an unusual situation in which that would actually work -- as fields cannot fire events when modified, it would be difficult to have a listener that was always notified when a field value changed.

Parameters:

memberName - the name of the field or method being proxied

listenerClass - the type of listener which receives events when the field or method is updated

modelName - the JavaBeans-style name of the model property

addMethod - add method name

removeMethod - remove method name

Parameters:

object - the object on which to set the property

propertyName - the name of the property to set

stringValue - the raw string value of the property from the XML

inline - true if the value was directly specified as an inline class tag attribute, false otherwise (a default value, specified in CSS, etc.)

public String getGetPropertyCode(String javaCode,
                        String name,
                        JAXXCompiler compiler)

Returns a snippet of Java code which will retrieve an object property at runtime. Typically the code is just a call to the property's get method, but it can be arbitrarily complex.

Parameters:

javaCode - Java code for the object whose property is being retrieved

name - the name of the property to retrieve

compiler - the current JAXXCompiler

Returns:

the snippet

Throws:

CompilerException - if a compilation error occurs

getSetPropertyCode

public String getSetPropertyCode(String javaCode,
                        String name,
                        String valueCode,
                        JAXXCompiler compiler)

Returns a snippet of Java code which will set an object property at runtime. Typically the code is just a call to the property's set method, but it can be arbitrarily complex.

Parameters:

javaCode - Java code for the object whose property is being set

name - the name of the property to set

valueCode - Java expression representing the value to set the property to

compiler - the current JAXXCompiler

Returns:

the snippet

Throws:

CompilerException - if a compilation error occurs

setProperty

public void setProperty(CompiledObject object,
               String name,
               Object value,
               JAXXCompiler compiler)

Appends Java code to a CompiledObject in order to implement a property assignment. setProperty is invoked in response to most XML attributes (those which are not more complicated cases, like data bindings or event handlers).

By the time it reaches this method, the value has already been converted from its XML string representation to the appropriate destination type for the property (i.e. if JLabel.foreground is being set, value will be a Color).

Parameters:

object - the object being modified

name - the name of the property to set

value - the value to set the property to

compiler - the current JAXXCompiler

Throws:

CompilerException - if a compilation error occurs

constantValue

protected int constantValue(String key,
                String value)

Maps string values onto integers, so that int-valued enumeration properties can be specified by strings. For example, when passed a key of 'alignment', this method should normally map the values 'left', 'center', and 'right' onto SwingConstants.LEFT, SwingConstants.CENTER, and SwingConstants.RIGHT respectively.

You do not normally need to call this method yourself; it is invoked by convertFromString(java.lang.String, java.lang.String, java.lang.Class<?>) when an int-valued property has a value which is not a valid number. By default, this method looks at the enumerationValues value of the JAXXPropertyDescriptor.

Parameters:

key - the name of the int-typed property

value - the non-numeric value that was specified for the property

Returns:

the constant integer value

Throws:

IllegalArgumentException - if the property is an enumeration, but the value is not valid

NumberFormatException - if the property is not an enumeration

convertFromString

protected Object convertFromString(String key,
                       String value,
                       Class<?> type)

As TypeManager.convertFromString(String, Class), except that it additionally supports constant names for int-valued types.

Parameters:

key - the name of the property whose value is being converted

value - the raw string value of the property as it appears in the XML

type - the datatype to convert the string into

Returns:

the converted object
