Method Detail

getInstancesSizeof

public AEntity getInstancesSizeof(boolean zero_case)
                           throws SdaiException

Returns entity instances aggregate for which the Express expression SIZEOF(that entity instances aggregate) = d is violated, where d is a nonnegative integer value. If d=0, then the method's parameter shall be set to true, otherwise null is returned. Also null is returned when the above equality is satisfied.

Parameters:

zero_case - true if SIZEOF value is required to be zero, false otherwise.

Returns:

aggregate of entity instances.

Throws:

SdaiException

Since:

4.1.0

getError

public java.lang.Throwable getError()

Returns Throwable if during validation of this where rule an error in Express expressions or in the population submitted for validation was found, and null otherwise.

Returns:

Throwable in the case if error occurred; null otherwise.
