ValueType (Blazegraph Database Platform 2.1.5 API)

java.lang.Object
- java.lang.Enum<ValueType>
- - com.bigdata.sparse.ValueType

All Implemented Interfaces:

Serializable, Comparable<ValueType>
```
public enum ValueType
extends Enum<ValueType>
```
A type safe enumeration of value types. This class also supports encoding and decoding of instances of the enumerated value types and is used for encoding and decoding of column values.

- Method Detail
  - values
```
public static ValueType[] 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 (ValueType c : ValueType.values())
    System.out.println(c);
```
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ValueType 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
  - intValue
```
public int intValue()
```
    An integer that identifies the type safe enumeration value.
    
    Returns:
  - valueOf
```
public static ValueType valueOf(int code)
```
  - getBuffer
```
public static DataOutputBuffer getBuffer()
```
    Return a ThreadLocal buffer that is used to serialize values.
  - encode
```
public static byte[] encode(Object v)
```
    Encode an object that is an instance of a supported class.
    
    Parameters:
    v - The value.
    
    Returns:
    The serialized byte[] encoding that value -or- null iff the value is null.
    
    Throws:
    
    UnsupportedOperationException - if the value is not an instance of a supported class.
  - decode
```
public static Object decode(byte[] v)
```
    Parameters:
    v -
    
    Returns:
