Interface IAddressSerializer

All Superinterfaces:

Serializable

All Known Implementing Classes:

AddressSerializer, PackedAddressSerializer

Deprecated. Along with NodeSerializer by the IRabaCoder

public interface IAddressSerializer
extends Serializable

Interface for (de-)serialization of addresses of child nodes and leaves as recorded on a Node.

Note: it is possible to use additional information from the IAddressManager associated with an IRawStore to decide how to (de-)serialize the addresses. This does have the effect of making the binary format of the serialized addresses different from store to store, e.g., if the #of offset bits is different on the two stores. However, we do NOT copy index nodes using a binary format from one store to another. Instead, overflow processing uses an ITupleIterator to visit the keys and values and replicate them onto the new store.

Method Summary

void	getChildAddresses(IAddressManager addressManager, DataInput is, long[] childAddr, int nchildren) Deprecated. De-serialize the child addresses for a node.
void	putChildAddresses(IAddressManager addressManager, DataOutputBuffer os, long[] childAddr, int nchildren) Deprecated. Serialize the child addresses for a node.

Method Detail

getChildAddresses

void getChildAddresses(IAddressManager addressManager,
                       DataInput is,
                       long[] childAddr,
                       int nchildren)
                       throws IOException

Deprecated.

De-serialize the child addresses for a node.

Parameters:

is - The input stream.

childAddr - The array into which the addresses must be written.

nchildren - The #of valid values in the array. The values in indices [0:n-1] are defined and must be read from the buffer and written on the array.

Throws:

IOException

putChildAddresses

void putChildAddresses(IAddressManager addressManager,
                       DataOutputBuffer os,
                       long[] childAddr,
                       int nchildren)
                       throws IOException

Deprecated.

Serialize the child addresses for a node.

Parameters:

os - The output stream.

childAddr - The array of child addresses to be written.

nchildren - The #of valid values in the array. The values in indices [0:n-1] are defined and must be written.

Throws:

IOException
