Interface Flags<T extends LexicalContextNode>

Type Parameters:

T - lexical context node that can have flags set during code generation

All Known Implementing Classes:

Block, FunctionNode

public interface Flags<T extends LexicalContextNode>

Interface implemented by all nodes that have flags in a lexical context. This is needed as we sometimes have to save the setting of flags in the lexical context until a block is completely finished and its final version (after multiple copy on writes) is placed in the lexical context

Method Summary

Modifier and Type	Method and Description
boolean	getFlag(int flag) Check if a flag is set in a lexical context node
int	getFlags() Get all flags of a LexicalContextNode
T	setFlag(LexicalContext lc, int flag) Set a flag of a LexicalContextNode
T	setFlags(LexicalContext lc, int flags) Set all flags of a LexicalContextNode, overwriting previous flags

Method Detail

getFlags

int getFlags()

Get all flags of a LexicalContextNode

Returns:

flags

getFlag

boolean getFlag(int flag)

flags

setFlag

T setFlag(LexicalContext lc,
          int flag)

Set a flag of a LexicalContextNode

Parameters:

setFlags

T setFlags(LexicalContext lc,
           int flags)
