public class JboLengthValidator
A validator that tests the length of the attribute values by comparing them with a pre-defined length value.
The length to be validated is designated as the left-hand operand of a relation operation. The validator provides the right-hand operand, the comparison datatype and the relation operator.

public JboLengthValidator()
The methods setOperType()
,setDataType()
and setRhsValue()
must be invoked before validation can be performed.
public JboLengthValidator(boolean inverse, int operType, int dataType, java.lang.Object rhsValue)
inverse
- if true
the logic of this validator's
comparison relation is inverted.operType
- this validator's comparison operator;
one of the comparison operator constants defined in this class.dataType
- this validator's comparison datatype;
one of the datatype constants defined in this class.rhsValue
- this validator's right-hand operand,
a reference object containing a numeric value.Method Detail |

public boolean validateValue(java.lang.Object value)
The length of the value
parameter is the left-hand
operand of this validator's comparison relation.
The operator is set by setOperType()
and the right-hand operand is the value set by setRhsValue()
.
This method is called by AbstractValidator#vetoableChange()
.
validateValue

- the object whose length is to be validated.
true
if the relation holds, or
false
if the relation does not hold or
if the operator or an operand is invalid or uninitialized.public void setOperType(int typeArg)
