Class Method

java.lang.Object

gnu.bytecode.Method

All Implemented Interfaces:

AttrContainer, Member

public class Method
extends java.lang.Object
implements AttrContainer, Member

Represents a method in a ClassType.

A Method contain a CodeAttr object; the interface for generating bytecode instructions is primarily in CodeAttr.

All the methods whose name start with compile_ are deprecated, and should not be used; use the methods in CodeAttrinstead.

Constructor Detail

Method

public Method(Method base,
      ClassType clas)

A copy constructor, except you can override the declaring class. This can be used to improve binary compatibility by emitting method references where the declared class is the type of the receiver.

Method Detail

getAttributes

public final Attribute getAttributes()

Description copied from interface: AttrContainer

Get the (first) Attribute of this container.

Specified by:

getAttributes in interface AttrContainer

setAttributes

public final void setAttributes(Attribute attributes)

Description copied from interface: AttrContainer

Set the (list of) Attributes of this container.

Specified by:

setAttributes in interface AttrContainer

getExceptionAttr

public final ExceptionsAttr getExceptionAttr()

setExceptions

public void setExceptions(short[] exn_indices)

setExceptions

public void setExceptions(ClassType[] exn_types)

getCode

public final CodeAttr getCode()

makeCloneMethod

public static Method makeCloneMethod(Type returnType)

Make a generic "clone" method. This is used for array types.

setStaticFlag

public final void setStaticFlag(boolean is_static)

getStaticFlag

public final boolean getStaticFlag()

Specified by:

getStaticFlag in interface Member

isAbstract

public final boolean isAbstract()

isNative

public final boolean isNative()

allocate_local

public void allocate_local(Variable local)

Deprecated.

Allocate slots for a local variable (or parameter).

Parameters:

startCode

public CodeAttr startCode()

Recommended method to create a new CodeAttr for this Method.

compile_checkcast

Deprecated.

Comple code to push the contents of a local variable onto the statck.

Parameters:

var - The variable whose contents we want to push.

Deprecated.

compile_store_value
