Method Detail

symbolAdded

public void symbolAdded(GrammarSymbolEvent gse)

This method is required by the GrammarSymbolListener interface. It should not be called directly.

Specified by:

symbolAdded in interface GrammarSymbolListener

Parameters:

gse - Contains details of the event.

symbolRemoved

public void symbolRemoved(GrammarSymbolEvent gse)

This method is required by the GrammarSymbolListener interface. It should not be called directly.

Specified by:

symbolRemoved in interface GrammarSymbolListener

Parameters:

gse - Contains details of the event.

symbolModified

public void symbolModified(GrammarSymbolEvent gse)

This method is required by the GrammarSymbolListener interface. It should not be called directly.

Specified by:

symbolModified in interface GrammarSymbolListener

Parameters:

gse - Contains details of the event.

save

Parameters:

filename - The name of the file where the state will be saved to.

Returns:

true if successful, false otherwise.

load

public boolean load(java.lang.String filename)

remove

public boolean remove(DrawableToken t)

Overrides this method in the TokenCanvas class.

Overrides:

remove in class TokenCanvas

Parameters:

t - The token to be removed. Must be a terminal symbol in the grammar.

Returns:

true if successful, or false if the token could not be removed from the Interpreter.

getInterpreter

public Interpreter getInterpreter()

Returns the Interpreter used by the canvas.
