public class JboSQLCompareValidator

extends JboCompareValidator

A validator that tests literal values by comparing them to a database value, using a pre-defined relation.

The value to be validated is designated as the left-hand operand of a relation operation. The validator provides the relation operator and the SQL statement that retrieves the right-hand operand.

Constructor Detail

JboSQLCompareValidator

public JboSQLCompareValidator()

Creates an uninitialized compare validator.

The methods setType() and setRhsValue() must be invoked before validation can be performed.

JboSQLCompareValidator

protected JboSQLCompareValidator(boolean bInverse,
                                 int operType)

Creates an partially-initialized compare validator.

The method setRhsValue() must be invoked before validation can be performed.

Parameters:

operType - this validator's comparison operator; one of the comparison operator constants defined in this class.

JboSQLCompareValidator

public JboSQLCompareValidator(boolean bInverse,
                              int operType,
                              java.lang.Object owner,
                              java.lang.Object rValue)

Creates an initialized compare validator.

Parameters:

operType - this validator's comparison operator; one of the comparison operator constants defined in this class.

owner - the attribute that owns this validator.

rValue - this validator's right-hand operand; an instance of AttributeDefImpl.
