Annotation Type MatrixParam


@Target(value={PARAMETER,METHOD,FIELD})
@Retention(value=RUNTIME)
public @interface MatrixParam

Binds the value(s) of a URI matrix parameter to a resource method parameter, resource class field, or resource class bean property. Values are URL decoded unless this is disabled using the Encoded annotation. A default value can be specified using the DefaultValue annotation. The type T of the annotated parameter, field or property must either:

  1. Be a primitive type
  2. Have a constructor that accepts a single String argument
  3. Have a static method named valueOf that accepts a single String argument (see, for example, Integer.valueOf(String))
  4. Be List<T>, Set<T> or SortedSet<T>, where T satisfies 2 or 3 above. The resulting collection is read-only.

If the type is not one of those listed in 4 above then the first value (lexically) of the parameter is used.

Because injection occurs at object creation time, use of this annotation on resource class fields and bean properties is only supported for the default per-request resource class lifecycle. Resource classes using other lifecycles should only use this annotation on resource method parameters.

Element Detail

value

public abstract java.lang.String value
Defines the name of the URI matrix parameter whose value will be used to initialize the value of the annotated method argument, class field or bean property.

The supplied value is automatically percent encoded. Note that percent encoded values are allowed in the value, an implementation will recognize such values and will not double encode the '%' character.
