MethodGenerator

public MethodGenerator(int access_flags,
               Type return_type,
               Type[] arg_types,
               String[] arg_names,

Method Detail

addLocalVariable

public LocalVariableGen addLocalVariable(String name,
                                Type type,
                                InstructionHandle start,
                                InstructionHandle end)

Allocates a local variable. If the slot allocator has already been initialized, then call addLocalVariable2() so that the new variable is known to the allocator. Failing to do this may cause the allocator to return a slot that is already in use.

Overrides:

addLocalVariable in class MethodGen

Parameters:

name - variable name

type - variable type

start - from where the variable is valid, if this is null, it is valid from the start

end - until where the variable is valid, if this is null, it is valid to the end

Returns:

new local variable object

removeLocalVariable

public void removeLocalVariable(LocalVariableGen lvg)

Description copied from class: MethodGen

Remove a local variable, its slot will not be reused, if you do not use addLocalVariable with an explicit index argument.

Overrides:

public int getLocalIndex(String name)

getLocalVariable

public LocalVariableGen getLocalVariable(String name)

setMaxLocals

public void setMaxLocals()

Description copied from class: MethodGen

Compute maximum number of local variables.

Overrides:

setMaxLocals in class MethodGen

addInstructionList

public void addInstructionList(Pattern pattern,
                      InstructionList ilist)

Add a pre-compiled pattern to this mode.

getInstructionList

public InstructionList getInstructionList(Pattern pattern)

Get the instruction list for a pre-compiled pattern. Used by test sequences to avoid compiling patterns more than once.

outlineChunks

public Method[] outlineChunks(ClassGenerator classGen,
                     int originalMethodSize)

Breaks up the IL for this MethodGenerator into separate outlined methods so that no method exceeds the 64KB limit on the length of the byte code associated with a method.

Parameters:

classGen - The ClassGen with which the generated methods will be associated

originalMethodSize - The number of bytes of bytecode represented by the InstructionList of this method

Returns:

an array of the outlined Methods and the original method itself

markChunkStart

public void markChunkStart()

Mark the end of the method's InstructionList as the start of an outlineable chunk of code. The outlineable chunk begins after the InstructionHandle that is at the end of the method's InstructionList, or at the start of the method if the InstructionList is empty. See OutlineableChunkStart for more information.

markChunkEnd

public void markChunkEnd()

Mark the end of an outlineable chunk of code. See OutlineableChunkStart for more information.
