public interface IFunctionBinding
A method binding represents a method or constructor of a class or interface.
Method bindings usually correspond directly to method or
constructor declarations found in the source code.
However, in certain cases of references to a generic method,
the method binding may correspond to a copy of a generic method
declaration with substitutions for the method's type parameters
(for these, getTypeArguments returns a non-empty
list, and either isParameterizedMethod or
isRawMethod returns true).
And in certain cases of references to a method declared in a
generic type, the method binding may correspond to a copy of a
method declaration with substitutions for the type's type
parameters (for these, getTypeArguments returns
an empty list, and both isParameterizedMethod and
isRawMethod return false).
This interface is not intended to be implemented by clients.
Provisional API: This class/interface is part of an interim API that is still under development and expected to
change significantly before reaching stability. It is being made available at this early stage to solicit feedback
from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken
(repeatedly) as the API evolves.| Field Summary |

boolean isConstructor()

compiler-generated default constructor, and false

java.lang.Object getDefaultValue()
null if the member has no default value, or if this
is not the binding for an annotation type member.
Resolved values are represented as follows (same as for
IMemberValuePairBinding#getValue()):
ITypeBinding for the class objectIVariableBinding for the enum constantIAnnotationBindingObject[] whose elements are as per above
(the language only allows single dimensional arrays in annotations)
null
if none or not applicableITypeBinding[] getParameterTypes()
Note that the binding for the last parameter type of a vararg method
declaration like void fun(Foo... args) is always for
an array type (i.e., Foo[]) reflecting the the way varargs
get compiled. However, the type binding obtained directly from
the SingleVariableDeclaration for the vararg parameter
is always for the type as written; i.e., the type binding for
Foo.
Note: The result does not include synthetic parameters introduced by inner class emulation.
ITypeBinding getReturnType()
void return type for constructors.
void return type for constructorsIFunctionBinding getMethodDeclaration()
#isParameterizedMethod())
and raw methods (#isRawMethod()), this method returns the binding
for the corresponding generic method. For other method bindings, this
returns the same binding.
Note: The one notable exception is the method Object.getClass(),
which is declared to return Class<? extends Object>, but
when invoked its return type becomes Class<? extends
R>, where R is the compile type of
the receiver of the method invocation.
boolean isSubsignature(IFunctionBinding otherMethod)
true if this method's signature is a subsignature of the given methodboolean isVarargs()
Note: Variable arity ("varargs") methods were added in JLS3.
