public enum EdmType
extends Enum<EdmType>

A enumeration used to represent the primitive types of the Entity Data Model (EDM) in the Open Data Protocol (OData). The EDM is the underlying abstract data model used by OData services. The EdmType enumeration includes a parse(String) method to convert EDM data type names to the enumeration type, and overrides the toString() method to produce an EDM data type name.

For more information about OData, see the Open Data Protocol website.

For an overview of the available EDM primitive data types and names, see the Primitive Data Types section of the OData Protocol Overview.

The Abstract Type System used to define the primitive types supported by OData is defined in detail in [MC-CSDL] (section 2.2.1).

Method Detail

values

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

Returns:

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

valueOf

public static EdmType 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

parse

public static EdmType parse(String value)

Parses an EDM data type name and return the matching EdmType enumeration value. A null or empty value parameter is matched as STRING. Note that only the subset of EDM data types supported in Microsoft Azure Table storage is parsed, consisting of BINARY, BOOLEAN, BYTE , DATE_TIME, DOUBLE, GUID, INT32, INT64, and STRING. Any other type will cause an IllegalArgumentException to be thrown.

Parameters:

value - A String containing the name of an EDM data type.

Returns:

The EdmType enumeration value matching the specified EDM data type.

Throws:

IllegalArgumentException - if an EDM data type not supported in Microsoft Azure Table storage is passed as an argument.

toString

public String toString()

Returns the name of the EDM data type corresponding to the enumeration value.

Overrides:

toString in class Enum<EdmType>

Returns:

A String containing the name of the EDM data type.
