Constructor Detail

WeakReferenceValue

public WeakReferenceValue(javax.jcr.Node target)
                   throws javax.jcr.RepositoryException

Constructs a ReferenceValue object representing the UUID of an existing node.

Parameters:

target - the node to be referenced

Throws:

java.lang.IllegalArgumentException - If target is nonreferenceable.

javax.jcr.RepositoryException - If another error occurs.

Method Detail

valueOf

public static WeakReferenceValue valueOf(java.lang.String s)
                                  throws javax.jcr.ValueFormatException

Returns a new ReferenceValue initialized to the value represented by the specified String.

The specified String must denote the UUID of an existing node.

Parameters:

s - the string to be parsed.

Returns:

a newly constructed ReferenceValue representing the the specified value.

Throws:

javax.jcr.ValueFormatException - If the String is not a valid not a valid UUID format.

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this one.

The result is true if and only if the argument is not null and is a ReferenceValue object that represents the same value as this object.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

hashCode

public int hashCode()

Returns zero to satisfy the Object equals/hashCode contract. This class is mutable and not meant to be used as a hash key.

Overrides:

hashCode in class java.lang.Object

Returns:

always zero
