Interface BooleanArrayResult

All Superinterfaces:

DBExpression, ExpressionCanHaveNullValues

All Known Implementing Classes:

BooleanArrayColumn, BooleanArrayExpression, DBBooleanArray

public interface BooleanArrayResult
extends DBExpression, ExpressionCanHaveNullValues

Interface required to be implemented by all DBExpressions that produce BIT results

DBvolution attempts to maintain type safety using the *Result interfaces. Most operations requiring a bit type will not accept anything other than an actual bit type.

Add implements BooleanArrayResult to your class and override the copy method so that it returns your class type.

Method Detail

copy

BooleanArrayResult copy()

Description copied from interface: DBExpression

A Complete Copy Of This DBValue.

Immutability in DBvolution is maintain by internally copying objects.

This method enables immutability by performing a deep copy of the object.

Singletons may return themselves but all other objects must return a new instance with copies of all mutable fields.
