Constructor Detail

PathValue

protected PathValue(String value)
             throws javax.jcr.ValueFormatException

Creates an instance for the given path value.

Throws:

javax.jcr.ValueFormatException

Method Detail

getType

public int getType()

Returns PropertyType.PATH.

getString

public String getString()
                 throws javax.jcr.ValueFormatException,
                        javax.jcr.RepositoryException

Returns the string representation of the path value.

Throws:

javax.jcr.ValueFormatException

javax.jcr.RepositoryException

getStream

public final InputStream getStream()
                            throws javax.jcr.RepositoryException

Returns the stream representation of this value. This method implements the deprecated JCR 1.0 behaviour of always returning the same stream instance. The stream is retrieved from a Binary instance returned by getBinary().

Specified by:

getStream in interface javax.jcr.Value

Returns:

stream representation of this value

Throws:

javax.jcr.RepositoryException - if the stream can not be created

getBinary

public javax.jcr.Binary getBinary()
                           throws javax.jcr.RepositoryException

Returns the binary representation of this value. The default implementation uses the UTF-8 serialization of the string returned by Value.getString(). Subclasses

Specified by:

getBinary in interface javax.jcr.Value

Throws:

javax.jcr.RepositoryException

getBoolean

public boolean getBoolean()
                   throws javax.jcr.ValueFormatException

Always throws a ValueFormatException. Implementations should overwrite if conversion to boolean is supported.

Specified by:

getBoolean in interface javax.jcr.Value

Returns:

nothing

Throws:

javax.jcr.ValueFormatException - If the value cannot be converted to a boolean.

getDate

public Calendar getDate()
                 throws javax.jcr.ValueFormatException

Always throws a ValueFormatException. Implementations should overwrite if conversion to Calender is supported.

Specified by:

getDate in interface javax.jcr.Value

Returns:

nothing

Throws:

javax.jcr.ValueFormatException - If the value cannot be converted to a Calendar instance.

getDecimal

public BigDecimal getDecimal()
                      throws javax.jcr.RepositoryException

Always throws a ValueFormatException. Implementations should overwrite if conversion to a BigDecimal is supported.

Specified by:

getDecimal in interface javax.jcr.Value

Returns:

nothing

Throws:

javax.jcr.ValueFormatException - If the value cannot be converted to a BigDecimal.

javax.jcr.RepositoryException

getDouble

public double getDouble()
                 throws javax.jcr.ValueFormatException

Always throws a ValueFormatException. Implementations should overwrite if conversion to double is supported.

Specified by:

getDouble in interface javax.jcr.Value

Returns:

nothing

Throws:

javax.jcr.ValueFormatException - If the value cannot be converted to a double.

getLong

public long getLong()
             throws javax.jcr.ValueFormatException

Always throws a ValueFormatException. Implementations should overwrite if conversion to long is supported.

Specified by:

getLong in interface javax.jcr.Value

Returns:

nothing

Throws:

javax.jcr.ValueFormatException - If the value cannot be converted to a long.

getValueFormatException

protected javax.jcr.ValueFormatException getValueFormatException(String destType)

Returns a ValueFormatException with a message indicating what kind of type conversion is not supported.

Parameters:

destType - The name of the value type to which this value cannot be converted.

Returns:

nothing

equals

public boolean equals(Object object)

Compares values as defined in the JCR specification.

Overrides:

equals in class Object

Parameters:

object - value for comparison

Returns:

true if the values are equal, false otherwise

JCRRMI-16

hashCode

public int hashCode()

Returns a hash code that's in line with how the equals(Object) method is implemented.

Overrides:

hashCode in class Object

Returns:

hash code of this value

toString

public String toString()

Returns a string representation of this value.

Overrides:

toString in class Object

Returns:

value string
