isCachable

public boolean isCachable()

If caching is not supported, all reads of a variable's value require a fresh call to VariableType.getValue(ValueFields).

Specified by:

isCachable in interface VariableType

Returns:

whether variables of this type are cacheable.

public Object getValue(ValueFields valueFields)

Specified by:

getValue in interface VariableType

Returns:

the value of a variable based on the specified ValueFields.
