Method Detail

extract

public Map<Object,List<Object>> extract(Annotation annotation)

Description copied from interface: ValidationParameterExtractor

Extracts all ValidationParameters hosted by the given annotation. The wiki shows all supported styles.

Specified by:

extract in interface ValidationParameterExtractor

Parameters:

annotation - The annotation which might contain validation-parameters

Returns:

key/value map of the found parameters

extract

public List<Object> extract(Annotation annotation,
                            Object key)

Description copied from interface: ValidationParameterExtractor

Extracts all ValidationParameters for the given key which are hosted by the given annotation. The wiki shows all supported styles.

Specified by:

extract in interface ValidationParameterExtractor

Parameters:

annotation - The annotation for which we want to extract the information.

key - Value for the ParameterKey that is used for filtering the ValidationParameters.

Returns:

list of the found parameters

extract

public <T> List<T> extract(Annotation annotation,
                           Object key,
                           Class<T> valueType)

Description copied from interface: ValidationParameterExtractor

Extracts all ValidationParameters for the given key which are hosted by the given annotation. The result is filtered by the given type for the value. The wiki shows all supported styles.

Specified by:

extract in interface ValidationParameterExtractor

Type Parameters:

T - Class type of the result which is the same as the class type of the parameter valueType.

Parameters:

annotation - The annotation which might contain validation-parameters

key - Value for the ParameterKey that is used for filtering the ValidationParameters.

valueType - ParameterValue must be assignable to this type to be added to the result.

Returns:

list of the found parameters

extract

public <T> T extract(Annotation annotation,
                     Object key,
                     Class<T> valueType,
                     Class valueId)

Description copied from interface: ValidationParameterExtractor

Extracts all ValidationParameters for the given key which are hosted by the given annotation. The result is filtered by the given type for the value and the given id to receive a specific value if there are multiple parameters of the same type. The wiki shows all supported styles.

Specified by:

extract in interface ValidationParameterExtractor

Type Parameters:

T - Class type of the result which is the same as the class type of the parameter valueType.

Parameters:

annotation - The annotation which might contain validation-parameters

key - Value for the ParameterKey that is used for filtering the ValidationParameters.

valueType - ParameterValue must be assignable to this type to be added to the result.

valueId - marker which identifies a specific value (needed if there are multiple parameters of the same type)

Returns:

Value of the found ParameterValue.

extractById

public <T> List<T> extractById(Annotation annotation,
                               Object key,
                               Class<T> valueType,
                               Class valueId)

extractById

public List<Object> extractById(Annotation annotation,
                                Object key,
                                Class valueId)

extractById

public Map<Object,List<Object>> extractById(Annotation annotation,
                                            Class valueId)
