public abstract class AbstractJFlexCTokenMaker
extends AbstractJFlexTokenMaker

Base class for JFlex-based token makers using C-style syntax. This class knows how to:

• Auto-indent after opening braces and parens
• Automatically close multi-line and documentation comments

Method Detail

createInsertBreakAction

protected javax.swing.Action createInsertBreakAction()

Creates and returns the action to use when the user inserts a newline. The default implementation intelligently closes multi-line comments. Subclasses can override.

Returns:

The action.

See Also:

getInsertBreakAction()

getCurlyBracesDenoteCodeBlocks

public boolean getCurlyBracesDenoteCodeBlocks(int languageIndex)

Returns true always as C-style languages use curly braces to denote code blocks.

Specified by:

getCurlyBracesDenoteCodeBlocks in interface TokenMaker

Overrides:

getCurlyBracesDenoteCodeBlocks in class TokenMakerBase

Parameters:

languageIndex - The language index at the offset in question. Since some TokenMakers effectively have nested languages (such as JavaScript in HTML), this parameter tells the TokenMaker what sub-language to look at.

Returns:

true always.

getInsertBreakAction

public javax.swing.Action getInsertBreakAction()

Returns an action to handle "insert break" key presses (i.e. Enter). An action is returned that handles newlines differently in multi-line comments.

Specified by:

getInsertBreakAction in interface TokenMaker

Overrides:

getInsertBreakAction in class TokenMakerBase

Returns:

The action.

getMarkOccurrencesOfTokenType

public boolean getMarkOccurrencesOfTokenType(int type)

Description copied from class: TokenMakerBase

Returns whether tokens of the specified type should have "mark occurrences" enabled for the current programming language. The default implementation returns true if type is TokenTypes.IDENTIFIER. Subclasses can override this method to support other token types, such as TokenTypes.VARIABLE.

Specified by:

getMarkOccurrencesOfTokenType in interface TokenMaker

Overrides:

getMarkOccurrencesOfTokenType in class TokenMakerBase

Parameters:

type - The token type.

Returns:

Whether tokens of this type should have "mark occurrences" enabled.

getShouldIndentNextLineAfter

public boolean getShouldIndentNextLineAfter(Token t)

Description copied from class: TokenMakerBase

The default implementation returns false always. Languages that wish to better support auto-indentation can override this method.

Specified by:

getShouldIndentNextLineAfter in interface TokenMaker

Overrides:

getShouldIndentNextLineAfter in class TokenMakerBase

Parameters:

t - The token the previous line ends with.

Returns:

Whether the next line should be indented.
