Method Details

extract

public Collection<T> extract(javax.ws.rs.core.MultivaluedMap<String,String> parameters)

Description copied from interface: MultivaluedParameterExtractor

Extract the map entry identified by a name (and using the configured default value) from the supplied multivalued map.

Specified by:

extract in interface MultivaluedParameterExtractor<T>

Parameters:

parameters - multivalued parameter map.

Returns:

custom Java type instance representing the extracted multivalued map entry.

newCollection

protected abstract Collection<T> newCollection()

 javax.ws.rs.ext.ParamConverter<T> converter,
 String parameterName,
 String defaultValueString)

Get a new CollectionExtractor instance.

Type Parameters:

T - converted parameter Java type.

Parameters:

collectionType - raw collection type.

converter - parameter converter to be used to convert parameter string values into values of the requested Java type.

parameterName - parameter name.

defaultValueString - default parameter string value.

Returns:

new collection parameter extractor instance.
