Methods

Modifier and Type	Method and Description
Context	getContext() Returns the context in which this binding was created.
SourceSnippet	getCreationStatements(NameGenerator nameGenerator, java.util.List<InjectorMethod> methodsOutput) Gets one or more fully formed Java statements that create the bound value and store it in a new local variable named result.
java.util.Collection<Dependency>	getDependencies() Returns the set of dependencies that this binding produces.
java.lang.String	getGetterMethodPackage() Returns the package in which the getter for the bound key is created.

Method Detail

isConstantKey

public static boolean isConstantKey(Key<?> key)

Returns true if the provided key is a valid constant key, i.e. if a constant binding can be legally created for it.

Parameters:

key - key to check

Returns:

true if constant key

getCreationStatements

public SourceSnippet getCreationStatements(NameGenerator nameGenerator,
                                  java.util.List<InjectorMethod> methodsOutput)
                                    throws NoSourceNameException

Description copied from interface: Binding

Gets one or more fully formed Java statements that create the bound value and store it in a new local variable named result. If additional methods are to be created, the given NameGenerator should be used to choose their names, and they should be added to methodsOutput.

Specified by:

getCreationStatements in interface Binding

Throws:

NoSourceNameException - if source name is not available for type

getDependencies

public java.util.Collection<Dependency> getDependencies()

Description copied from interface: Binding

Returns the set of dependencies that this binding produces. This contains edges coming into the key that this type binds (from Dependency.GINJECTOR) as well as dependencies that this binding needs.

Specified by:

getDependencies in interface Binding

getContext

public Context getContext()

Description copied from interface: Binding

Returns the context in which this binding was created.

Specified by:

getContext in interface Binding

getGetterMethodPackage

public java.lang.String getGetterMethodPackage()

Description copied from interface: Binding

Returns the package in which the getter for the bound key is created. This is used by other bindings and by the top-level interface to determine which package this binding's method was written to. Implementors may assume that all other bindings have been created and placed in their respective GinjectorBindings objects.

Typically this will be the package containing the type that is returned by the getter, but the only requirement is that it has to be a package where the return type is visible.

Specified by:

getGetterMethodPackage in interface Binding

getMemberInjectRequests

public java.util.Collection<TypeLiteral<?>> getMemberInjectRequests()

Description copied from interface: Binding

Returns the set of types for which this binding requires member injection methods to be written.

Specified by:
