Field Detail

validators

private final AbstractValidator<? super K>[] validators

The child validators.

Constructor Detail

ValidatorMapKeys

@SafeVarargs
public ValidatorMapKeys(AbstractValidator<? super K>... validators)

The constructor.

Parameters:

validators - the AbstractValidators used to validate each element.

ValidatorMapKeys

public ValidatorMapKeys(List<AbstractValidator<? super K>> validators)

The constructor.

Parameters:

validators - the AbstractValidators used to validate each element.

Method Detail

getValidator

public AbstractValidator<?> getValidator(int index)

Description copied from interface: ComposedValueValidator

Gets the ValueValidator at the given index.

Specified by:

getValidator in interface ComposedValueValidator<Map<K,?>>

Parameters:

index - is the index of the ValueValidator to get.

Returns:

the requested ValueValidator.

See Also:

List.get(int)

getValidatorCount

public int getValidatorCount()

Specified by:

getValidatorCount in interface ComposedValueValidator<Map<K,?>>

Returns:

the number of validators.

See Also:

ComposedValueValidator.getValidator(int), Collection.size()

validate

public ValidationFailure validate(Map<K,?> map,
                                  Object valueSource)

Description copied from interface: ValueValidator

This method validates the given value.

Specified by:

validate in interface ValueValidator<Map<K,?>>

Parameters:

map - is the value to validate.

valueSource - is the source describing the origin of the given value. This may be the filename where the value was read from, an XPath where the value was located in an XML document, the label of a widget of the UI containing the value, etc. This will help to find the problem easier. 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 ValidationFailure or null if the given value is valid according to this ValueValidator.

hashCode

public int hashCode()

Specified by:

hashCode in class AbstractValidator<Map<K,?>>

equals

public boolean equals(Object obj)

Specified by:

equals in class AbstractValidator<Map<K,?>>
