Field Detail

WARNING_THRESHOLD

public static final int WARNING_THRESHOLD

The number of invalid consecutive generations that causes a warning

Constant Field Values

ERROR_THRESHOLD

public static final int ERROR_THRESHOLD

The number of invalid consecutive generations that causes an exception

See Also:

Constant Field Values

validator

protected org.databene.commons.Validator<P> validator

The validator used for validation

Constructor Detail

ValidatingGenerator

public ValidatingGenerator(org.databene.commons.Validator<P> validator)

Constructor that takes the validator

Method Detail

generate

public P generate()

Generator implementation that calls generateImpl() to generate values and validator.validate() in order to validate them. Consecutive invalid values are counted. If this count reaches the WARNING_THRESHOLD value, a warning is logged, if the count reaches the ERROR_THRESHOLD, an exception is raised.

generateImpl

protected abstract P generateImpl()

Callback method that does the job of creating values. This is to be implemented by child classes.
