public class ILazyParseableElementType
extends IElementType
implements ILazyParseableElementTypeBase

A token type which represents a fragment of text (possibly in a different language) which is not parsed during the current lexer or parser pass and can be parsed later when its contents is requested.

Method Detail

parseLight

@Deprecated
public PsiBuilder parseLight(ASTNode chameleon)

Deprecated. Not needed anymore, override parseContents(ASTNode) or implement ILightLazyParseableElementType instead.

Parses the contents of the specified chameleon node and returns PsiBuilder. In future this method should deprecate all other parsing methods: parseContents(), doParseContents(), etc. It provides more flexible and CPU/memory efficient access to parser algorithms for all needs: editing, indexing and analysis.

The parseContent() implementation in terms of parseLight() is just the following: parseLight().getTreeBuilt().getFirstChildNode()

Parameters:

chameleon - the node to parse.

Returns:

the parsed contents of the node in the form PsiBuilder.

parseContents

public ASTNode parseContents(ASTNode chameleon)

Parses the contents of the specified chameleon node and returns the AST tree representing the parsed contents.

Specified by:

parseContents in interface ILazyParseableElementTypeBase

Parameters:

chameleon - the node to parse.

Returns:

the parsed contents of the node.

doParseContents

protected ASTNode doParseContents(ASTNode chameleon,
                                  PsiElement psi)

getLanguageForParser

protected Language getLanguageForParser(PsiElement psi)

createNode

public ASTNode createNode(java.lang.CharSequence text)

reuseCollapsedTokens

public boolean reuseCollapsedTokens()

Specified by:

reuseCollapsedTokens in interface ILazyParseableElementTypeBase
