All Implemented Interfaces:

Serializable, Comparable<VTE>

public enum VTE
extends Enum<VTE>

Value Type Enumeration (IVTE) is a class with methods for interpreting and setting the bit flags used to identify the type of an RDF Value (URI, Literal, Blank Node, SID, etc).

Enum Constant Summary

Enum Constants

Enum Constant and Description
BNODE A blank node.
LITERAL A literal.
STATEMENT A statement identifier.
URI A URI.

Method Summary

Methods

Modifier and Type	Method and Description
char	getCharCode() Return the one character code for this RDF Value type (U, L, B, or S).
byte	v() Return the code for the value type.
static VTE	valueOf(byte b) Return the VTE identified by the LOW TWO (2) bits in the caller's value.
static VTE	valueOf(char c)
static VTE	valueOf(String name) Returns the enum constant of this type with the specified name.
static VTE	valueOf(org.openrdf.model.Value v) Determine the VTE based on the type of Value - URI, Literal, or BNode.
static VTE[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

URI

public static final VTE URI

A URI.

BNODE

public static final VTE BNODE

A blank node.

LITERAL

public static final VTE LITERAL

A literal.

STATEMENT

public static final VTE STATEMENT

A statement identifier.

Method Detail

values

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

Returns:

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

valueOf

public static VTE 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

v

public final byte v()

Return the code for the value type.

valueOf

public static VTE valueOf(byte b)

Return the VTE identified by the LOW TWO (2) bits in the caller's value.

Parameters:

b - The bit flags.

Returns:

The corresponding VTE.

AbstractIV.getVTE(byte)

getCharCode

public final char getCharCode()

Return the one character code for this RDF Value type (U, L, B, or S). This is used in various internal toString() implementations.

valueOf

public static final VTE valueOf(char c)

valueOf

public static final VTE valueOf(org.openrdf.model.Value v)

Determine the VTE based on the type of Value - URI, Literal, or BNode.
