Method Detail

insertLines

public void insertLines(int index,
                        int lines)

Description copied from class: TokenMarker

Informs the token marker that lines have been inserted into the document. This inserts a gap in the _lineInfoToken array.

Overrides:

insertLines in class TokenMarker

Parameters:

index - The first line number

lines - The number of lines

deleteLines

public void deleteLines(int index,
                        int lines)

Description copied from class: TokenMarker

Informs the token marker that line have been deleted from the document. This removes the lines in question from the _lineInfoToken array.

Overrides:

deleteLines in class TokenMarker

Parameters:

index - The first line number

lines - The number of lines

ensureCapacity

protected void ensureCapacity(int index)

Description copied from class: TokenMarker

Ensures that the _lineInfoToken array can contain the specified index. This enlarges it if necessary. No action is taken if the array is large enough already.

It should be unnecessary to call this under normal circumstances; insertLine() should take care of enlarging the line info array automatically.

Overrides:

ensureCapacity in class TokenMarker

Parameters:

index - The array index

markTokensImpl

public byte markTokensImpl(byte _token,
                           Segment line,
                           int lineIndex)

Description copied from class: TokenMarker

An abstract method that splits a line up into tokens. It should parse the line, and call addToken() to add syntax tokens to the token list. Then, it should return the initial token type for the next line.

For example if the current line contains the start of a multiline comment that doesn't end on that line, this method should return the comment token type so that it continues on the next line.

Specified by:

markTokensImpl in class TokenMarker

Parameters:

_token - The initial token type for this line

line - The line to be tokenized

lineIndex - The index of the line in the document, starting at 0

Returns:

The initial token type for the next line
