oracle.jbo.server.JboPrecisionScaleValidator

All Implemented Interfaces:

java.util.EventListener, JbiValidator, VetoableChangeListener

Deprecated.

use JboPrecisionScaleValidator instead

public class JboPrecisionScaleValidator
extends java.lang.Object
implements JbiValidator

Implements precision and scale validation for numeric attributes and length validation for string and character attributes. The framework applies this validator to Entity Object attributes whose definitions inlcude XML metadata precision or scale values.

This validator is invoked by an Entity Objects's validate() method when an attribute with defined precision or scale is modified.

JboPrecisionScaleValidator

public JboPrecisionScaleValidator()

Deprecated.

Creates a default validator.

Use setPrecision and setScale to configure the validatior.

Method Detail

vetoableChange

public void vetoableChange(PropertyChangeEvent evObj)
                    throws JboException

Deprecated.

Validates an Entity Object by invoking validateValue().

Specified by:

vetoableChange in interface VetoableChangeListener

Parameters:

evObj - an event object indicating the Entity Object to be validated.

Throws:

AttrSetValException - if validation fails.

JboException

validateValue

public boolean validateValue(java.lang.Object value)

Deprecated.

Tests the Entity Object against this validator's precision and scale values.

The precision value is the maximum allowed number of digits in a number, or the number of characters in a string. The scale value, when less than zero, is the minimum number of digits following the decimal point, and when greater than zero, is the minimum number of digits preceeding the decimal point.

Specified by:

validateValue in interface JbiValidator

Parameters:

value - the Entity Object to be tested.

Returns:

true if value is valid.

getPrecision

public int getPrecision()

Deprecated.

Gets the precision value. For strings, "precision" refers to length.

Returns:

the precision value.

getScale

public int getScale()

Deprecated.

Gets the scale value. If scale validation is not to be performed this value is -127.

setPrecision

public void setPrecision(int prec)

Deprecated.

Sets the precision value. For strings, "precision" refers to length.

Parameters:

prec - the new precision value.

setScale

public void setScale(int scale)

Deprecated.

Sets the scale value. If scale validation is not to be performed this value should be -127.

Parameters:

scale - the new scale value.

toString

public java.lang.String toString()

Deprecated.

Internal: Applications should not use this method.

Overrides:

toString in class java.lang.Object

getDescription

public java.lang.String getDescription()

Deprecated.

Gets the description of this validator.

Specified by:

getDescription in interface JbiValidator

Returns:

a documentation string.

setDescription

public void setDescription(java.lang.String description)

Deprecated.

Sets the description of this validator.

Specified by:

setDescription in interface JbiValidator

Parameters:

description - a documentation string.
