Serializable
,Comparable<TypeValuePolicy>
public enum TypeValuePolicy extends Enum<TypeValuePolicy>
The kind of values in theMetadataStandard.asTypeMap(…)
. This enumeration specifies whether the values shall be property types, element types (same as property types except for collections) or the declaring classes.- Since:
- 0.3
- See Also:
MetadataStandard.asTypeMap(Class, KeyNamePolicy, TypeValuePolicy)
Defined in the

module

PROPERTY_TYPE
public static final TypeValuePolicy PROPERTY_TYPE
The type of a property, as inferred from the return type of the property method defined in the interface.Notes:
- Collections are not handled in any special way: if the return type is a collection,
then the property type is
Collection.class
or any other declared return type. - As a special case, values of type
double
(the primitive type) inGeographicBoundingBox
are wrapped inLongitude
andLatitude
objects instead ofDouble
.
- Collections are not handled in any special way: if the return type is a collection,
then the property type is
-
ELEMENT_TYPE
public static final TypeValuePolicy ELEMENT_TYPE
The specialized type of a property, or type of elements if the property is a collection. This is the same type thanPROPERTY_TYPE
except for the following:- If the property is a collection, then the element type is the type of elements in that
collection. For example if the property type is
Collection<String>
, then the element type isString
. - If the implementation declares a more specific property type than the interface (as allowed by covariant return type), then the element type will be that specialized type.
- If the property is a collection, then the element type is the type of elements in that
collection. For example if the property type is
-
DECLARING_INTERFACE
public static final TypeValuePolicy DECLARING_INTERFACE
The type of the interface that declares the method. For any metadata object, different properties may have different declaring interfaces if some properties were inherited from parent interfaces.
-
DECLARING_CLASS
public static final TypeValuePolicy DECLARING_CLASS
The type of the class that declares the method. This is similar toDECLARING_INTERFACE
, except that the implementation class from the metadata standard is returned instead than the interface.

values
public static TypeValuePolicy[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (TypeValuePolicy c : TypeValuePolicy.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static TypeValuePolicy valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
- if this enum type has no constant with the specified nameNullPointerException
- if the argument is null
