setDirectiveName

public void setDirectiveName(String str)

Sets the directive name. Used by the parser. This keeps us from having to dig it out of the token stream and gives the parse the change to override.

Parameters:

str -

getDirectiveName

public String getDirectiveName()

Gets the name of this directive.

Returns:

The name of this directive.

toString

public String toString()

Overrides:

toString in class SimpleNode
