Class ArrayType.TypeableSizedArrayTypeTerm

java.lang.Object
  ptolemy.data.type.ArrayType.TypeableSizedArrayTypeTerm

All Implemented Interfaces:

InequalityTerm

Enclosing class:

ArrayType

private static class ArrayType.TypeableSizedArrayTypeTerm
extends java.lang.Object
implements InequalityTerm

An InequalityTerm representing an array types whose elements have the type of the specified typeable. The purpose of this class is to defer to as late as possible actually accessing the type of the typeable, since it may change dynamically. This term is not variable and cannot be set.

Field Summary

private ArrayType	_arrayType The array type with element types matching the typeable.
private int	_length
private Typeable	_typeable The associated typeable.

Constructor Summary

ArrayType.TypeableSizedArrayTypeTerm(Typeable typeable, int length)
Construct a term that will defer to the type of the specified typeable.

Method Summary

private ArrayType	_getArrayType() Get an array type with element type matching the type of the associated typeable.
private ArrayType	_getArrayTypeRaw() Get an array type with element type matching the type of the associated typeable.
java.lang.Object	getAssociatedObject() Return an array type with element types given by the associated typeable.
java.lang.Object	getValue() Return an array type with element types given by the associated typeable.
InequalityTerm[]	getVariables() Return an array of size zero.
void	initialize(java.lang.Object e) Throw an exception.
boolean	isSettable() Return false.
boolean	isValueAcceptable() Delegate to an array type with elements given by the type of the associated typeable.
void	setValue(java.lang.Object type) Throw an exception.
java.lang.String	toString() Delegate to an array type with elements given by the type of the associated typeable.
