Method Detail

init

public void init(SyntaxStyle[] styles,
                 java.awt.font.FontRenderContext fontRenderContext,
                 javax.swing.text.TabExpander expander,
                 java.util.List<Chunk> out,
                 float wrapMargin,
                 int physicalLineOffset)

Init some variables that will be used when marking tokens. This is called before JEditBuffer.markTokens(int, TokenHandler) to store some data that will be required and that we don't want to put in the parameters

Parameters:

styles -

fontRenderContext -

expander -

out -

wrapMargin -

physicalLineOffset - offset of the physical lines which these chunks belong to required for implementing elastic tabstops

getChunkList

public java.util.List<Chunk> getChunkList()

Returns the list of chunks. Each element is a head of linked chunks and represents a screen line.

Since:

jEdit 4.1pre7

handleToken

public void handleToken(javax.swing.text.Segment seg,
                        byte id,
                        int offset,
                        int length,
                        TokenMarker.LineContext context)

Called by the token marker when a syntax token has been parsed.

Specified by:

handleToken in interface TokenHandler

Overrides:

handleToken in class DefaultTokenHandler

Parameters:

seg - The segment containing the text

id - The token type (one of the constants in the Token class).

offset - The start offset of the token

length - The number of characters in the token

context - The line context

Since:
