ValueFactoryQImpl

public ValueFactoryQImpl(QValueFactory qfactory,
 NamePathResolver resolver)

Constructs a new ValueFactoryQImpl based on an existing SPI QValueFactory and a NamePathResolver.

Parameters:

qfactory - wrapped QValueFactory

resolver - wrapped NamePathResolver

Method Details

getQValueFactory

public QValueFactory getQValueFactory()

The QValueFactory that is wrapped by this ValueFactory instance.

Returns:

qfactory The QValueFactory wrapped by this instance.

createValue

public Value createValue(QValue qvalue)

Create a new Value based on an existing QValue

Parameters:

qvalue - existing QValue

Returns:

a Value representing the QValue

Specified by:

createValue in interface ValueFactory

Parameters:

value - a Node

Returns:

a Value of PropertyType.REFERENCE

Throws:

RepositoryException - if the specified Node is not referenceable, the current Session is no longer active, or another error occurs.

Specified by:

createValue in interface ValueFactory

Parameters:

value - a String

type - one of the constants defined in PropertyType.

Returns:

a Value of PropertyType type.

Throws:

ValueFormatException - if the specified value cannot be converted to the specified type.

createBinary
