VariableType
复制的描述
Indicates if this variable type supports caching.
If caching is supported, the result of VariableType.getValue(ValueFields)
is saved for the
duration of the session and used for subsequent reads of the variable's value.
If caching is not supported, all reads of a variable's value require a
fresh call to VariableType.getValue(ValueFields)
.
