Method Detail

addressOf

public static long addressOf(NdNode nullable)

load

public static NdNode load(Nd nd,
                          long address)

Load a node from the specified address in the given database. Return null if a node cannot be loaded.

Parameters:

nd - The Nd from which to load the node.

address - The address of the node in the given Nd.

Returns:

The NdNode at the specified location or null if a node cannot be loaded.

load

public static <T extends NdNode> T load(Nd nd,
                                        long address,
                                        java.lang.Class<T> clazz)

delete

public final void delete()

Invokes the destructor on this node and frees up its memory

getDB

protected Database getDB()

getNd

public Nd getNd()

getNodeType

public short getNodeType()

Return a value to uniquely identify the node within the factory that is responsible for loading instances of this node from the Nd.

getAddress

public final long getAddress()

getBindingID

public final long getBindingID()

equals

public final boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public final int hashCode()

Overrides:

hashCode in class java.lang.Object

accept

public void accept(INdVisitor visitor)

getNodeId

public static int getNodeId(int linkageID,
                            int nodeType)

Return an value to globally identify the given node within the given linkage. This value can be used for comparison with other NdNodes.

getByte

protected byte getByte(long offset)

Convenience method for fetching a byte from the database.

Parameters:

offset - Location of the byte.

Returns:

a byte from the database.

getBit

protected static boolean getBit(int bitVector,
                                int offset)

Returns the bit at the specified offset in a bit vector.

Parameters:

bitVector - Bits.

offset - The position of the desired bit.

Returns:

the bit at the specified offset.

destruct

public void destruct()

Dispose this NdNode. Subclasses should extend this method to perform any high-level node-specific cleanup. This will be invoked prior to disposing the fields. Implementations must invoke their parent's destruct method and should not destruct the fields.

If an external object wants to destroy a node, they should invoke delete() rather than this method.

Specified by:
