org.apache.bcel.classfile

Class Method

Implemented Interfaces:
Cloneable, Node, java.io.Serializable

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 Details

Method

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

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

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 Details

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.
Specified by:
accept in interface Node
Parameters:
v - Visitor object

copy

public final Method copy(ConstantPool constant_pool)
Returns:
deep copy of this method

getArgumentTypes

public Type[] getArgumentTypes()
Returns:
array of method argument types

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!

getLineNumberTable

public final LineNumberTable getLineNumberTable()
Returns:
LineNumberTable of code attribute if any, i.e. the call is forwarded to the Code atribute.

getLocalVariableTable

public final LocalVariableTable getLocalVariableTable()
Returns:
LocalVariableTable of code attribute if any, i.e. the call is forwarded to the Code atribute.

getReturnType

public Type getReturnType()
Returns:
return type of method

toString

public final String toString()
Return string representation close to declaration format, `public static void main(String[] args) throws IOException', e.g.
Returns:
String representation of the method.
