Constructor Detail

AbstractCount

public AbstractCount(java.lang.String name)

Creates a new object.
Parameters:: name - the name for debugging

Method Detail

getKey

protected java.lang.String getKey(Context context,
                                  TokenSource source,
                                  Typesetter typesetter)
                           throws InterpreterException

Return the key (the name of the primitive) for the numbered count register.

Parameters:: context - the interpreter context to use; source - the source for new tokens; typesetter - the typesetter
Returns:: the key for the current register
Throws:: InterpreterException - in case that a derived class need to throw an Exception this one is declared.

init

public void init(Context context,
                 TokenSource source,
                 Typesetter typesetter)
          throws InterpreterException

Description copied from interface: InitializableCode

Initialize the Code with some value coming from a String.

Specified by:: init in interface InitializableCode

Parameters:: context - the interpreter context; source - the source of information for the initialization; typesetter - the typesetter
Throws:: InterpreterException - in case of an error
