Method Detail

getCode

protected String getCode()

This is the default implementation to retrieve the code of this ValueValidator.
ATTENTION:
This default implementation returns the classname of the actual ValueValidator implementation. This strategy is chosen for simplicity when implementing a new validator. To ensure stable codes override this method and return a string constant. This shall at least be done when the name of the class is changed.

Returns:

the code.

validate

public final ValidationFailure validate(V value)

This method validates the given value.

Specified by:

validate in interface ValueValidator<V>

Parameters:

value - is the value to validate.

Returns:

the ValidationFailure or null if the given value is valid according to this ValueValidator.

isDynamic

public boolean isDynamic()

This method determines if this ValueValidator is dynamic. Here dynamic means that the validation of the same input may not always return the same validation result (e.g. it holds references to instances that have dynamic impact on the validation).

Returns:

true if this ValueValidator is dynamic, false otherwise.

isMandatory

public boolean isMandatory()

Returns:

true if this is a validator for mandatory fields (that will not accept null or empty values), false otherwise.

createBundle

protected <BUNDLE extends NlsBundle> BUNDLE createBundle(Class<BUNDLE> bundleInterface)

This is a convenience method delegating to NlsBundleFactory.createBundle(Class).

Type Parameters:

BUNDLE - is the generic type of the requested NlsBundle.

Parameters:

bundleInterface - the interface of the requested NlsBundle. Has to be a sub-interface of NlsBundle with according methods.

Returns:

an instance of the requested NlsBundle interface.
