public interface ScalarValued
extends TokenValued, ScalarTyped

A TokenValued object containing a scalar value. Unlike a RecordValued object, a ScalarValued object cannot be decomposed into smaller values.

Method Summary

Modifier and Type	Method and Description
ScalarTokenType	getType() Gets the data type of the token.
boolean	isZero() Indicates whether the value is the zero value for the type.

Method Detail

getType

ScalarTokenType getType()

Description copied from interface: TokenValued

Gets the data type of the token. This type will dictate the valid values that can be contained.

Specified by:

getType in interface ScalarTyped

Specified by:

getType in interface TokenTyped

Specified by:

getType in interface TokenValued

Returns:

the token type.

isZero

boolean isZero()

Indicates whether the value is the zero value for the type. Zero values are not stored in sparse representation formats.

Returns:

true if the value is the zero value, false otherwise.
