public class JboVOCompareValidator
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 View Object that accesses the right-hand operand.

Since:
Jdeveloper 3.0

Constructor Detail

JboVOCompareValidator

public JboVOCompareValidator()
Creates an uninitialized compare validator.

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


JboVOCompareValidator

protected JboVOCompareValidator(boolean inverse,
                                int operType)
Creates an partially-initialized compare validator.

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

Parameters:
inverse - if true the sense of this validator's comparison relation is inverted.
operType - this validator's comparison operator; one of the comparison operator constants defined in this class.

JboVOCompareValidator

public JboVOCompareValidator(boolean inverse,
                             int operType,
                             java.lang.Object owner,
                             java.lang.Object rValue)
Creates an initialized compare validator.
Parameters:
inverse - if true the sense of this validator's comparison relation is inverted.
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; a View Object.
Method Detail

setRhsValue

public void setRhsValue(java.lang.Object rhsValue)
Sets the right-side operand of this validator's expression.
Overrides:
setRhsValue in class JboCompareValidator
Parameters:
rhsValue - a View Object.

getRhsValue

public java.lang.Object getRhsValue()
Gets the right-side operand of this validator's expression.
Overrides:
getRhsValue in class JboCompareValidator
Returns:
the first value of the first row of data retrieved by the View Object's SQL statement.

setOwner

public void setOwner(java.lang.Object owner)
Sets the attribute that owns this validator.
Parameters:
owner - an attribute.

toString

public java.lang.String toString()
Internal: For debugging purposes only.
Overrides:
toString in class JboCompareValidator
