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.

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()

getModifiers

public int getModifiers()

Specified by:

getModifiers in interface Member

setModifiers

public void setModifiers(int modifiers)

getConstants

public final ConstantPool getConstants()

pushScope

public Scope pushScope()

reachableHere

public final boolean reachableHere()

True if control could reach here.

popScope

public Scope popScope()

allocate_local

public void allocate_local(Variable local)

Deprecated.

Allocate slots for a local variable (or parameter).

Parameters:

local - the variable we need to allocate

initCode

public void initCode()

Allocate a Code attribute, and prepare to generate code. Most code generators should use the startCode convenience method.

init_param_slots

Deprecated. Use startCode instead

startCode

public CodeAttr startCode()

Recommended method to create a new CodeAttr for this Method.

compile_checkcast

Parameters:

var - The variable whose contents we want to push.

compile_push_value

public void compile_push_value(Variable var)

Deprecated.

compile_store_value

public void compile_store_value(Variable var)

Deprecated.
