Class JboRegExpValidator

java.lang.Object
oracle.jbo.rules.AbstractValidator
oracle.jbo.rules.JboAbstractValidator
oracle.jbo.rules.JboRegExpValidator

All Implemented Interfaces:

JboValidatorInterface

public class JboRegExpValidator

extends JboAbstractValidator

implements JboValidatorInterface

A validator that tests attribute values by comparing them with a pre-defined regular expression.

The value to be validated is designated as the left-hand operand of a relation operation. The validator provides the right-hand operand

Since:

Jdeveloper 3.0

Constructor Detail

JboRegExpValidator

public JboRegExpValidator()

Creates an uninitialized regular expression validator.

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

JboRegExpValidator

public JboRegExpValidator(boolean inverse,
                          java.lang.String patternArg,
                          java.lang.String flagValueArg)

Creates an initialized regular expression validator.

Parameters:

inverse - if true the logic of this validator's comparison relation is inverted.

patternArg - this validator's right-hand operand, a reference object containing a regular expression.

flagValueArg - validator's match flags

Method Detail

initialize

protected void initialize(JboValidatorContext evObj)

Overrides:

initialize in class JboAbstractValidator

validateValue

public boolean validateValue(java.lang.Object value)

Validate an object by matching it with a pre-defined regular expression.

The value parameter is the left-hand operand of this validator's regular expression comparison relation. The right-hand operand is the value set by setPattern().

This method is called by AbstractValidator#vetoableChange().

Specified by:

validateValue in class JboAbstractValidator

Parameters:

value - the object to be validated.

Returns:

true if the relation holds, or false if the relation does not hold or operand is invalid or uninitialized.

setPattern

public void setPattern(java.lang.String patternArg)

Sets the right-side operand of this validator's expression.

Parameters:

patternArg - a reference object containing a regular expression.

getPattern

public java.lang.String getPattern()

Gets the right-side operand of this validator's expression.

setFlagValue

public void setFlagValue(java.lang.String flagValueArg)

Sets the match flags for the regular expression comparison.

Parameters:

flagValueArg - a reference object containing String representation of the match flags.

getFlagValue

public java.lang.String getFlagValue()

Gets the match flags for the regular expression comparison.

toString

public java.lang.String toString()

Internal: For debugging purposes only.

getRegExpFlagInt

public static int getRegExpFlagInt(java.lang.String flagStr)

Gets the computed int value of the regular expression match flags.

getKeyValue

protected static int getKeyValue(java.lang.String flagValue,
                                 java.lang.String keyString,
                                 int keyValue)

Internal:
