Class CharacterBinding

java.lang.Object

com.sleepycat.bind.tuple.TupleBase<E>

com.sleepycat.bind.tuple.TupleBinding<java.lang.Character>

com.sleepycat.bind.tuple.CharacterBinding

All Implemented Interfaces:

EntryBinding<java.lang.Character>

public class CharacterBinding
extends TupleBinding<java.lang.Character>

A concrete TupleBinding for a Character primitive wrapper or a char primitive.

There are two ways to use this class:

1. When using the com.sleepycat.je package directly, the static methods in this class can be used to convert between primitive values and DatabaseEntry objects.
2. When using the com.sleepycat.collections package, an instance of this class can be used with any stored collection. The easiest way to obtain a binding instance is with the TupleBinding.getPrimitiveBinding(java.lang.Class<T>) method.

Method Detail

entryToObject

public java.lang.Character entryToObject(TupleInput input)

Description copied from class: TupleBinding

Constructs a key or data object from a TupleInput entry.

Specified by:

entryToObject in class TupleBinding<java.lang.Character>

Parameters:

input - is the tuple key or data entry.

Returns:

the key or data object constructed from the entry.

objectToEntry

public void objectToEntry(java.lang.Character object,
                 TupleOutput output)

Description copied from class: TupleBinding

Converts a key or data object to a tuple entry.

Specified by:

objectToEntry in class TupleBinding<java.lang.Character>

Parameters:

object - is the key or data object.

output - is the tuple entry to which the key or data should be written.

getTupleOutput

protected TupleOutput getTupleOutput(java.lang.Character object)

Description copied from class: TupleBase

Returns an empty TupleOutput instance that will be used by the tuple binding or key creator.

The default implementation of this method creates a new TupleOutput with an initial buffer size that can be changed using the TupleBase.setTupleBufferSize(int) method.

This method may be overridden to return a TupleOutput instance. For example, an instance per thread could be created and returned by this method. If a TupleOutput instance is reused, be sure to call its FastOutputStream.reset() method before each use.

Overrides:

getTupleOutput in class TupleBase<java.lang.Character>

Parameters:

object - is the object to be written to the tuple output, and may be used by subclasses to determine the size of the output buffer.

Returns:

an empty TupleOutput instance.

TupleBase.setTupleBufferSize(int)

entryToChar

public static char entryToChar(DatabaseEntry entry)

Converts an entry buffer into a simple char value.

Parameters:

entry - is the source entry buffer.

Returns:

the resulting value.

charToEntry

public static void charToEntry(char val,
               DatabaseEntry entry)

Converts a simple char value into an entry buffer.

Parameters:

val - is the source value.

entry - is the destination entry buffer.
