Constructor Detail

JboListValidator

public JboListValidator()

Creates an uninitialized list validator.

Invoke setList() to provide a list of comparison values.

JboListValidator

public JboListValidator(boolean inverse,
                        java.util.Vector vec)

Creates a list validator.

Parameters:

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

vec - a list of comparison values.

Method Detail

validateValue

public boolean validateValue(java.lang.Object value)

Validate that an object is present in a list of values.

The list of test values is set by setList.

This method is called by JboBaseValidator#vetoableChange().

Specified by:

validateValue in interface JbiValidator

Specified by:

validateValue in class JboBaseValidator

Parameters:

value - the object to be validated.

Returns:

true if value is in this validator's list of values.

setList

public void setList(java.util.Vector vec)

Sets this validator's list of comparison values.

Parameters:

vec - a list of values.

getList

public java.util.Vector getList()

Gets this validator's list of comparison values.

Returns:

a list of values.

toString

public java.lang.String toString()

Internal: For debugging purposes only.

convertToVector

public static java.util.Vector convertToVector(java.lang.String listVal)

Converts a string representation of values to a vector.

Parameters:

listVal - a string containing values separated by ":" characters.
