Fields Summary

Constructors Summary
public Method() Empty constructor, all attributes have to be defined via `setXXX' methods. Use at your own risk.
public Method(Method c) Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy. super(c);
Method(DataInputStream file, ConstantPool constant_pool) Construct object from file stream. param file Input stream throw IOException throw ClassFormatError super(file, constant_pool);
public Method(int access_flags, int name_index, int signature_index, Attribute[] attributes, ConstantPool constant_pool) param access_flags Access rights of method param name_index Points to field name in constant pool param signature_index Points to encoded signature param attributes Collection of attributes param constant_pool Array of constants super(access_flags, name_index, signature_index, attributes, constant_pool);

Methods Summary
public void	accept(com.sun.org.apache.bcel.internal.classfile.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. param v Visitor object v.visitMethod(this);
public final com.sun.org.apache.bcel.internal.classfile.Method	copy(com.sun.org.apache.bcel.internal.classfile.ConstantPool constant_pool) return deep copy of this method return (Method)copy_(constant_pool);
public final com.sun.org.apache.bcel.internal.classfile.Code	getCode() return Code attribute of method, if any for(int i=0; i < attributes_count; i++) if(attributes[i] instanceof Code) return (Code)attributes[i]; return null;
public final com.sun.org.apache.bcel.internal.classfile.ExceptionTable	getExceptionTable() return ExceptionTable attribute of method, if any, i.e., list all exceptions the method may throw not exception handlers! for(int i=0; i < attributes_count; i++) if(attributes[i] instanceof ExceptionTable) return (ExceptionTable)attributes[i]; return null;
public final com.sun.org.apache.bcel.internal.classfile.LineNumberTable	getLineNumberTable() return LineNumberTable of code attribute if any, i.e. the call is forwarded to the Code atribute. Code code = getCode(); if(code != null) return code.getLineNumberTable(); else return null;
public final com.sun.org.apache.bcel.internal.classfile.LocalVariableTable	getLocalVariableTable() return LocalVariableTable of code attribute if any, i.e. the call is forwarded to the Code atribute. Code code = getCode(); if(code != null) return code.getLocalVariableTable(); else return null;
public final java.lang.String	toString() Return string representation close to declaration format, `public static void main(String[] args) throws IOException', e.g. return String representation of the method. ConstantUtf8 c; ConstantValue cv; String name, signature, access; // Short cuts to constant pool String exceptions; StringBuffer buf; Attribute[] attr; access = Utility.accessToString(access_flags); // Get name and signature from constant pool c = (ConstantUtf8)constant_pool.getConstant(signature_index, Constants.CONSTANT_Utf8); signature = c.getBytes(); c = (ConstantUtf8)constant_pool.getConstant(name_index, Constants.CONSTANT_Utf8); name = c.getBytes(); signature = Utility.methodSignatureToString(signature, name, access, true, getLocalVariableTable()); buf = new StringBuffer(signature); for(int i=0; i < attributes_count; i++) { Attribute a = attributes[i]; if(!((a instanceof Code) || (a instanceof ExceptionTable))) buf.append(" [" + a.toString() + "]"); } ExceptionTable e = getExceptionTable(); if(e != null) { String str = e.toString(); if(!str.equals("")) buf.append("\n\t\tthrows " + str); } return buf.toString();
