IeDatum

public IeDatum(byte[] array)

Constructs a new datum with a byte array as its value. Use a factory method instead of calling this constructor directly.

Parameters:

array - The byte array.

IeDatum

public IeDatum(Date date)

Constructs a new datum with a Date as its value. Use a factory method instead of calling this constructor directly.

IeDatum

public IeDatum(Number number)

Constructs a new datum with a Number as its value. This accommodates BigDecimal, BigInteger, Byte, Double, Integer, Short, Long, and Float. Use a factory method instead of calling this constructor directly.

IeDatum

public IeDatum(String string)

Constructs a new datum with a String as its value. Use a factory method instead of calling this constructor directly.

IeDatum

public IeDatum(Object object)

Constructs a new datum with an Object as its value. Use a factory method instead of calling this constructor directly.

Parameters:

object - The Object value.

Method Detail

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
                         ClassNotFoundException

Specified by:

readExternal in interface Externalizable

IOException

ClassNotFoundException

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

newIeDatum

public static IeDatum newIeDatum(Object object)

Factory method that accepts an object and constructs an instance with an appropriate type.

Parameters:

object - The Object value.

newIeDatum

public static IeDatum newIeDatum(AttributeIdentifier identifier,
                                 Object object)

Factory method that accepts an object and constructs an instance with an appropriate type and a specific attribute identifier value.

Parameters:

identifier - The identifier to associate with the value.

object - The Object value.

toString

public String toString()

Returns the String representation of the value associated with this datum.

Returns:

The String representation of this datum.

rawValueOf

public Object rawValueOf()

Returns the raw value of this datum.

Returns:

The raw value of this datum.

setValue

public void setValue(Object value)

Sets the raw value of this datum.

Parameters:

value - The new value.

rawValueType

public String rawValueType()

Returns the type of the raw value of this datum.

Returns:

The type of the raw value of this datum.

getIdentifier

public AttributeIdentifier getIdentifier()

Returns the attribute identifier associated with this datum.

Returns:

The attribute identifier, or null if no identifier is currently associated.

getIdentifier

public AttributeIdentifier getIdentifier(TypeInstanceIdentifier typeInstanceId,
