Method Detail

validate

public ValidationResult validate(V value,
                                 Object valueSource)

Description copied from interface: Validator

This method validates the given value.

Parameters:

value - is the value to validate.

valueSource - is the source describing the origin of the given value. The source needs to have a reasonable string-representation as this may be displayed to the end-user to locate the source of the failure. In most cases it is suitable to directly pass a String.

Returns:

the ValidationResult.

validateNull

protected io.github.mmm.base.i18n.Localizable validateNull()

This method performs the validation in case null was provided as value. By default null should be considered as a legal value. Only for validators such as mandatory validator this method should be overridden.

Returns:

the failure message or null if null is valid.

validateNotNull

protected abstract io.github.mmm.base.i18n.Localizable validateNotNull(V value)

This method performs the validation in case value is NOT null. This method contains the actual custom logic for the validation. It is therefore designed in a way that makes it most simple to implement custom validators.

Parameters:

value - the value to validate.

Returns:

the failure message or null if the the given value is valid.
