public final class Method

extends FieldOrMethod

This class represents the method info structure, i.e., the representation for a method in the class. See JVM specification for details. A method has access flags, a name, a signature and a number of attributes.

Constructor Summary

Method()
Empty constructor, all attributes have to be defined via `setXXX' methods.

Constructor Detail

Method

public Method()

Empty constructor, all attributes have to be defined via `setXXX' methods. Use at your own risk.

Method

public Method(Method c)

Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.

Method

public Method(int access_flags,
              int name_index,
              int signature_index,
              Attribute[] attributes,
              ConstantPool constant_pool)

Parameters:

access_flags - Access rights of method

name_index - Points to field name in constant pool

signature_index - Points to encoded signature

attributes - Collection of attributes

constant_pool - Array of constants

Method Detail

accept

public void accept(Visitor v)

Called by objects that are traversing the nodes of the tree implicitely defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.

Parameters:

v - Visitor object

getCode

public final Code getCode()

Returns:

Code attribute of method, if any

getExceptionTable

public final ExceptionTable getExceptionTable()

Returns:

ExceptionTable attribute of method, if any, i.e., list all exceptions the method may throw not exception handlers!

getLocalVariableTable

public final LocalVariableTable getLocalVariableTable()

Returns:

LocalVariableTable of code attribute if any, i.e. the call is forwarded to the Code atribute.

getLineNumberTable

public final LineNumberTable getLineNumberTable()

Returns:

LineNumberTable of code attribute if any, i.e. the call is forwarded to the Code atribute.

toString

public final java.lang.String toString()

Return string representation close to declaration format, `public static void main(String[] args) throws IOException', e.g.

Overrides:

toString in class java.lang.Object

Returns:

String representation of the method.

copy

public final Method copy(ConstantPool constant_pool)

Returns:

deep copy of this method
