Method Detail

getRequiredClosingTags

public static final java.util.Set<java.lang.String> getRequiredClosingTags()

getTagNameTokenForCaretOffset

public static final Token getTagNameTokenForCaretOffset(RSyntaxTextArea textArea,
                                                        OccurrenceMarker occurrenceMarker)
If the caret is inside of a tag, this method returns the token representing the tag name; otherwise, null is returned.

Currently, this method only checks for tag names on the same line as the caret, for simplicity. In the future it could check prior lines until the tag name is found.

Parameters:
textArea - The text area.
occurrenceMarker - The occurrence marker.
Returns:
The token to mark occurrences of. Note that, if the specified occurrence marker identifies tokens other than tag names, these other element types may be returned.

getTokenToMark

public Token getTokenToMark(RSyntaxTextArea textArea)
Returns the token to mark occurrences, of, provided it matches the criteria put forth by OccurrenceMarker.isValidType(RSyntaxTextArea, Token). For most languages, this method should return the token at the caret position.

Specified by:
getTokenToMark in interface OccurrenceMarker
Parameters:
textArea - The text area.
Returns:
The token to (possibly) mark occurrences of, or null if none.

isValidType

public boolean isValidType(RSyntaxTextArea textArea,
                           Token t)
Returns whether the specified token is a type that we can do a "mark occurrences" of. Typically, this will delegate to RSyntaxTextArea.getMarkOccurrencesOfTokenType(int).

Specified by:
isValidType in interface OccurrenceMarker
Parameters:
textArea - The text area.
t - The token.
Returns:
Whether we should mark all occurrences of this token.

markOccurrences

public void markOccurrences(RSyntaxDocument doc,
                            Token t,
                            RSyntaxTextAreaHighlighter h,
                            SmartHighlightPainter p)
Called when occurrences of a token should be marked.

Specified by:
markOccurrences in interface OccurrenceMarker
Parameters:
doc - The document.
t - The document whose relevant occurrences should be marked.
h - The highlighter to add the highlights to.
p - The painter for the highlights.
