Method Detail

isCachable

public boolean isCachable()

Description copied from interface: VariableType

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).

Specified by:

isCachable in interface VariableType

Overrides:

isCachable in class JPAEntityListVariableType

Returns:

whether variables of this type are cacheable.
