This token.

_add

protected ScalarToken _add(ScalarToken rightArgument)
                    throws IllegalActionException

Throw an exception.

Specified by:

_add in class ScalarToken

Parameters:

rightArgument - The token to add to this token.

Returns:

A new token containing the result.

Throws:

IllegalActionException - If this method is not supported by the derived class.

_bitwiseAnd

protected ScalarToken _bitwiseAnd(ScalarToken rightArgument)
                           throws IllegalActionException

Throw an exception.

Specified by:

_bitwiseAnd in class ScalarToken

Parameters:

rightArgument - The ScalarToken to bitwise AND with this one.

Returns:

The bitwise AND.

Throws:

IllegalActionException - If the given token is not compatible for this operation, or the operation does not make sense for this type.

_bitwiseNot

protected ScalarToken _bitwiseNot()
                           throws IllegalActionException

Throw an exception.

Specified by:

_bitwiseNot in class ScalarToken

Returns:

The bitwise NOT of this token.

Throws:

IllegalActionException - If the given token is not compatible for this operation, or the operation does not make sense for this type.

_bitwiseOr

protected ScalarToken _bitwiseOr(ScalarToken rightArgument)
                          throws IllegalActionException

Throw an exception.

Specified by:

_bitwiseOr in class ScalarToken

Parameters:

rightArgument - The ScalarToken to bitwise OR with this one.

Returns:

The bitwise OR.

Throws:

IllegalActionException - If the given token is not compatible for this operation, or the operation does not make sense for this type.

_bitwiseXor

protected ScalarToken _bitwiseXor(ScalarToken rightArgument)
                           throws IllegalActionException

Throw an exception.

Specified by:

_bitwiseXor in class ScalarToken

Parameters:

rightArgument - The ScalarToken to bitwise XOR with this one.

Returns:

The bitwise XOR.

Throws:

IllegalActionException - If the given token is not compatible for this operation, or the operation does not make sense for this type.

_divide

protected ScalarToken _divide(ScalarToken rightArgument)
                       throws IllegalActionException

Throw an exception.

Specified by:

_isCloseTo in class ScalarToken

Parameters:

rightArgument - The token to compare to this token.

epsilon - The value that we use to determine whether two tokens are close.

Returns:
