Class SerialValueFactory

java.lang.Object
  org.apache.jackrabbit.rmi.value.SerialValueFactory

All Implemented Interfaces:

ValueFactory

public class SerialValueFactory
extends Object
implements ValueFactory

The SerialValueFactory class is used in the RMI infrastructure to create serializable Value instances on the client side.

This class works in conjunction with the implementations of the javax.jcr.Value interface found in this package.

This class may be extended to overwrite any of the createXXXValue methods to create instances of the respective type of org.apache.jackrabbit.rmi.value.StatefullValueimplementation. The methods of the ValueFactory interface are declared final to guard against breaking the rules.

Constructor Detail

SerialValueFactory

protected SerialValueFactory()

Default constructor only visible to extensions of this class. See class comments for details.

Method Detail

getInstance

public static final SerialValueFactory getInstance()

Returns the ValueFactory instance, which currently is a singleton instance of this class.

Future revisions will support some kind of configuration to specify which concrete class should be used.

makeSerialValueArray

public static Value[] makeSerialValueArray(Value[] values)
                                    throws RepositoryException

Utility method for decorating an array of values. The returned array will contain serializable value decorators for all the given values. Note that the contents of the original values will only be copied when the decorators are serialized.

If the given array is null, then an empty array is returned.

Parameters:

values - the values to be decorated

Returns:

array of decorated values

Throws:

RepositoryException - if the values can not be serialized

makeSerialValue

public static Value makeSerialValue(Value value)
                             throws RepositoryException

Utility method for decorating a value. Note that the contents of the original values will only be copied when the decorators are serialized. Null referenced and already serializable values are passed as-is.

Parameters:

value - the value to be decorated, or null

Returns:

the decorated value, or null

Throws:

RepositoryException - if the value can not be serialized

makeSerialValueArray

public static Value[] makeSerialValueArray(String[] values)

Utility method for converting an array of strings to serializable string values.

If the given array is null, then an empty array is returned.

Parameters:

values - the string array

Returns:

array of string values
