Class MemberCollector

java.lang.Object

com.google.gwt.inject.rebind.util.MemberCollector

public class MemberCollector
extends java.lang.Object

This class can be used to collect a type's members, including those of its (recursive) superclasses and interfaces. The collector treats overrides correctly, i.e. it returns the method defined the closest to the provided type.

Note: The collector uses internal caching and can be called with the same arguments repeatedly without repeated performance costs.

This class is not thread-safe.

                    throws java.lang.IllegalStateException

Sets this collector's field filter. This method can only be called before members are requested.

Parameters:

filter - new field filter for this collector

Throws:

java.lang.IllegalStateException - if the filter is set after members have been requested

getMethods

public java.util.Collection<MethodLiteral<?,java.lang.reflect.Method>> getMethods(TypeLiteral<?> typeLiteral)

Returns all methods in the provided type, including those of the type's (recursive) super classes and interfaces. Treats overloads correctly. If no method filter is set will return an empty set.

Parameters:

typeLiteral - type for which methods are collected

Returns:

all methods for the given type

getFields

public java.util.Collection<FieldLiteral<?>> getFields(TypeLiteral<?> typeLiteral)
