Method Detail

createValue

Value createValue(String value)

Returns a Value object of PropertyType.STRING with the specified value.

Parameters:

value - a String

Returns:

a Value of PropertyType.STRING

createValue

Value createValue(String value,
                  int type)
           throws ValueFormatException

Returns a Value object of the PropertyType specified by type with the specified value.

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.

createValue

Value createValue(long value)

Returns a Value object of PropertyType.LONG with the specified value.

Parameters:

value - a long

Returns:

a Value of PropertyType.LONG

createValue

Value createValue(double value)

Returns a Value object of PropertyType.DOUBLE with the specified value.

Parameters:

value - a double

Returns:

a Value of PropertyType.DOUBLE

createValue

Value createValue(BigDecimal value)

Returns a Value object of PropertyType.DECIMAL with the specified value.

Parameters:

value - a double

Returns:

a Value of PropertyType.DECIMAL

Since:

JCR 2.0

createValue

Value createValue(boolean value)

Returns a Value object of PropertyType.BOOLEAN with the specified value.

Parameters:

value - a boolean

Returns:

a Value of PropertyType.BOOLEAN

createValue

Value createValue(Calendar value)

Returns a Value object of PropertyType.DATE with the specified value.

Parameters:

value - a Calendar

Returns:

a Value of PropertyType.DATE

Throws:

IllegalArgumentException - if the specified value cannot be expressed in the ISO 8601-based format defined in the JCR 2.0 specification and the implementation does not support dates incompatible with that format.

createValue

Value createValue(InputStream value)

Deprecated.

As of JCR 2.0, createValue(Binary) should be used instead.

Returns a Value object of PropertyType.BINARY with a value consisting of the content of the specified InputStream.

The passed InputStream is closed before this method returns either normally or because of an exception.

Parameters:

value - an InputStream

Returns:

a Value of PropertyType.BINARY

createValue

Value createValue(Binary value)

Returns a Value object of PropertyType.BINARY with a value consisting of the content of the specified Binary.

Parameters:

value - a Binary

Returns:

a Value of PropertyType.BINARY

Since:

JCR 2.0

createValue

Value createValue(Node value)
           throws RepositoryException

Returns a Value object of PropertyType.REFERENCE that holds the identifier of the specified Node. This Value object can then be used to set a property that will be a reference to that Node.

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.

createValue

Value createValue(Node value,
                  boolean weak)
           throws RepositoryException

Returns a Value object of PropertyType.REFERENCE (if weak is false) or PropertyType.REFERENCE (if weak is true) that holds the identifier of the specified Node. This Value object can then be used to set a property that will be a reference to that Node.

Parameters:

value - a Node

weak - a boolean. If true then a PropertyType.WEAKREFERENCE is created, otherwise a PropertyType.REFERENCE is created.

Returns:

a Value of PropertyType.REFERENCE or PropertyType.REFERENCE

Throws:

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

createBinary

Binary createBinary(InputStream stream)
             throws RepositoryException

Returns a Binary object with a value consisting of the content of the specified InputStream.

The passed InputStream is closed before this method returns either normally or because of an exception.

Parameters:

stream - an InputStream

Returns:

a Binary

Throws:

RepositoryException - if an error occurs.
