Constructor Detail

QValueValue

public QValueValue(QValue qvalue,
                   NamePathResolver resolver)

Constructs a QValueValue object representing an SPI QValue.

Parameters:

qvalue - the QValue this QValueValue should represent

resolver - fore resolving namespace URIs to prefixes in NAME/PATH properties

Method Detail

getQValue

public QValue getQValue()

Returns the embedded QValue.

Returns:

the embedded QValue

getBoolean

public boolean getBoolean()
                   throws RepositoryException

Description copied from interface: Value

Returns a Boolean representation of this value.

Specified by:

getBoolean in interface Value

Returns:

A Boolean representation of this value.

Throws:

ValueFormatException - if conversion to a Boolean is not possible.

RepositoryException - if another error occurs.

See Also:

Value.getBoolean()

getDecimal

public BigDecimal getDecimal()
                      throws ValueFormatException,
                             IllegalStateException,
                             RepositoryException

Description copied from interface: Value

Returns a BigDecimal representation of this value.

Specified by:

getDecimal in interface Value

Returns:

A BigDecimal representation of this value.

Throws:

ValueFormatException - if conversion to a BigDecimal is not possible.

RepositoryException - if another error occurs.

IllegalStateException

See Also:

Value.getDecimal()

getBinary

public Binary getBinary()
                 throws RepositoryException

Description copied from interface: Value

Returns a Binary representation of this value. The Binary object in turn provides methods to access the binary data itself. Uses the standard conversion to binary (see JCR specification).

Specified by:

getBinary in interface Value

Returns:

A Binary representation of this value.

Throws:

RepositoryException - if an error occurs.

See Also:

Value.getBinary()

getDate

public Calendar getDate()
                 throws RepositoryException

Description copied from interface: Value

Returns a Calendar representation of this value.

The object returned is a copy of the stored value, so changes to it are not reflected in internal storage.

Specified by:

getDate in interface Value

Returns:

A Calendar representation of this value.

Throws:

ValueFormatException - if conversion to a Calendar is not possible.

RepositoryException - if another error occurs.

See Also:

Value.getDate()

getDouble

public double getDouble()
                 throws RepositoryException

Description copied from interface: Value

Returns a double representation of this value.

Specified by:

getDouble in interface Value

Returns:

A double representation of this value.

Throws:

ValueFormatException - if conversion to a double is not possible.

RepositoryException - if another error occurs.

See Also:

Value.getDouble()

getLong

public long getLong()
             throws RepositoryException

Description copied from interface: Value

Returns a long representation of this value.

Specified by:

getLong in interface Value

Returns:

A long representation of this value.

Throws:

ValueFormatException - if conversion to an long is not possible.

RepositoryException - if another error occurs.

See Also:

Value.getLong()

getStream

public InputStream getStream()
                      throws IllegalStateException,
                             RepositoryException

Description copied from interface: Value

Returns an InputStream representation of this value. Uses the standard conversion to binary (see JCR specification).

It is the responsibility of the caller to close the returned InputStream.

Specified by:

getStream in interface Value

Returns:

An InputStream representation of this value.

Throws:

RepositoryException - if an error occurs.

IllegalStateException

See Also:

Value.getStream()

getString

public String getString()
                 throws RepositoryException

Description copied from interface: Value

Returns a String representation of this value.

Specified by:

getString in interface Value

Returns:

A String representation of the value of this property.

Throws:

ValueFormatException - if conversion to a String is not possible.

RepositoryException - if another error occurs.

See Also:

Value.getString()

getType

public int getType()

Description copied from interface: Value

Returns the type of this Value. One of:

• PropertyType.STRING
• PropertyType.DATE
• PropertyType.BINARY
• PropertyType.DOUBLE
• PropertyType.DECIMAL
• PropertyType.LONG
• PropertyType.BOOLEAN
• PropertyType.NAME
• PropertyType.PATH
