NodeId

public NodeId(String uuid)

Creates a node identifier instance for the identified node.

Parameters:

uuid - node UUID

Method Detail

denotesNode

public boolean denotesNode()

Returns true as this class represents a node identifier, not a property identifier.

Specified by:

denotesNode in class ItemId

Returns:

always true

ItemId.denotesNode()

getUUID

public String getUUID()

Returns the UUID of the identified node.

Returns:

node UUID

valueOf

public static NodeId valueOf(String s)
                      throws IllegalArgumentException

Returns a NodeId holding the value of the specified string. The string must be in the format returned by the NodeId.toString() method.

Parameters:

s - a String containing the NodeId representation to be parsed.

Returns:

the NodeId represented by the argument

Throws:

IllegalArgumentException - if the specified string can not be parsed as a NodeId.

equals

public boolean equals(Object obj)

Compares node identifiers for equality.

Parameters:

obj - other object

Returns:

true if the given object is a node identifier instance that identifies the same node as this identifier, false otherwise

Object.equals(Object)

toString

public String toString()

Returns the node UUID.

Returns:

node UUID

Object.toString()

hashCode

public int hashCode()

Returns the hash code of the node UUID. The computed hash code is memorized for better performance.

Returns:

hash code
