Field Detail

private final ValidationState delegate

The wrapped ValidationState.

Constructor Detail

AbstractValidationStateCollector

public AbstractValidationStateCollector(ValidationState delegate)

The constructor.

Parameters:

delegate - is the ValidationState to adapt.

Method Detail

getDelegate

protected ValidationState getDelegate()

Returns:

the ValidationState to adapt. Each call to onFailure(ValidationFailure) will also be propagated to this delegate.

onFailure

public void onFailure(ValidationFailure failure)

Description copied from interface: ValidationCollector

This method gets called if a ValidationFailure occurred.

Specified by:

onFailure in interface ValidationCollector

Parameters:

failure - is the new ValidationFailure.

getFailureCount

public int getFailureCount()

Specified by:

getFailureCount in interface ValidationCollector

Returns:

the number of ValidationFailures that have been collected.

isValid

public boolean isValid()

This method determines if the validation has been successful.
ATTENTION:
This method only returns false if a ValidationFailure has been collected by this instance. It may therefore return true even if the delegate would return false.

Specified by:

isValid in interface ValidationState

Returns:

true if no ValidationFailure has been collected, false otherwise.
