Field Detail

MAX_INT_VALUE

public static final int MAX_INT_VALUE

Maximum integer value in any supported Prolog. XSB Prolog uses 28 bits. Unfortunately, it is pointless to intercept writeInt in ObjectOutputStream, because

1. the method is invoked in several situations, not just to serialize int values, and
2. some classes may serialize in very weird ways

so in general it is not possible to detect int values beyond these boundaries
