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

supportsMultilineTokens

public boolean supportsMultilineTokens()

Description copied from class: TokenMarker

Returns if the token marker supports tokens that span multiple lines. If this is true, the object using this token marker is required to pass all lines in the document to the markTokens() method (in turn).

The default implementation returns true; it should be overridden to return false on simpler token markers for increased speed.
