All Known Implementing Classes:

public interface MethodInfo
extends MemberInfo

An interface that provides information about methods. This can be used to describe both MethodGenerators that are used to generate code and pre-existing Java classes.

Method Summary

java.util.List<Variable>	arguments() Return a list of arguments for this method.
java.util.List<Type>	exceptions() Return a list of all Exception types that are declared as being throwable from this method.
java.lang.reflect.Constructor	getConstructor() Return the Constructor that is represented by this MethodInfo, or null if no such Constructor instance exists (because this MethodInfo represents a Constructor being generated, rather than a Constructor in a Class that is loaded into the VM).
java.lang.reflect.Method	getMethod() Return the Method that is represented by this MethodInfo, or null if no such Method instance exists (because this MethodInfo represents a Method being generated, rather than a Method in a Class that is loaded into the VM).
boolean	isConstructor() Returns true if this is a constructor, false if method.
Type	returnType() Return the Type that is returned by this method.
Signature	signature() Return the signature of this method.

Method Detail

isConstructor

boolean isConstructor()

Returns true if this is a constructor, false if method.

returnType

Type returnType()

Return the Type that is returned by this method.

exceptions

java.util.List<Type> exceptions()

Return a list of all Exception types that are declared as being throwable from this method.

arguments

java.util.List<Variable> arguments()

Return a list of arguments for this method.

signature

Signature signature()

Return the signature of this method.

getMethod

java.lang.reflect.Method getMethod()

Return the Method that is represented by this MethodInfo, or null if no such Method instance exists (because this MethodInfo represents a Method being generated, rather than a Method in a Class that is loaded into the VM).

Throws:

java.lang.IllegalStateException - if isConstructor() is true.

getConstructor

java.lang.reflect.Constructor getConstructor()

Return the Constructor that is represented by this MethodInfo, or null if no such Constructor instance exists (because this MethodInfo represents a Constructor being generated, rather than a Constructor in a Class that is loaded into the VM).

Throws:

java.lang.IllegalStateException - if isConstructor() is false.
