Enum DataTypeEnum

java.lang.Enum<DataTypeEnum>

org.apache.stanbol.entityhub.servicesapi.defaults.DataTypeEnum

All Implemented Interfaces:

Serializable, Comparable<DataTypeEnum>

public enum DataTypeEnum
extends Enum<DataTypeEnum>

Defines the data types that need to be supported by the model implementation.

Each data type defines:

• short name: An short and human readable ID that is unique within the list of data types. Currently prefix:localName is used as short name and prefixes are used as defined by the NamespaceEnum.
• uri: Ths is the global unique UD of the namespace. If possible the URI defined by XSD is used (e.g. http://www.w3.org/2001/XMLSchema#string for strings).
• java class: Each data type is mapped to exactly one preferred and 0..n optional java representations. Note that different data types may use the same preferred as well as optional java class meaning. This means that the java class can not be used to uniquely identify a data type.

The Enum.name() is not used, but typically the local name with an capital first letter is used. The URI of the data type is used by the implementation of toString().

In addition the the definition of all the data types this class also provides several utilities for getting the data type by short name, URI as well as preferred or all defined java class mappings.

Method Detail

values

public static DataTypeEnum[] 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 (DataTypeEnum c : DataTypeEnum.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DataTypeEnum 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 name

NullPointerException - if the argument is null
