Method Detail

getFollowElements

public Collection<FollowElement> getFollowElements(IParseResult parseResult,
                                          int offset,
                                          boolean strict)

Specified by:

getFollowElements in interface IPartialContentAssistParser

strict - if true the parser will not use error recovery on the very last token of the input.

getEntryGrammarElement

protected AbstractElement getEntryGrammarElement(ICompositeNode entryPoint)

getTextToParse

protected String getTextToParse(IParseResult parseResult,
                    ICompositeNode entryPoint,
                    int offset)

appendTextToParse

protected boolean appendTextToParse(ICompositeNode node,
                        int offset,
                        boolean skipOptional,
                        StringBuilder result)

getReplacement

protected String getReplacement(ICompositeNode node)

Returns a syntactically correct replacement for nodes whose real content does not need to be parsed.

Returns:

the replacement or null

getFollowElements

protected Collection<FollowElement> getFollowElements(AbstractInternalContentAssistParser parser,
                                          AbstractElement entryPoint)
