Class BooleanBinding

java.lang.Object

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

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

com.sleepycat.bind.tuple.BooleanBinding

All Implemented Interfaces:

EntryBinding<java.lang.Boolean>

public class BooleanBinding
extends TupleBinding<java.lang.Boolean>

A concrete TupleBinding for a Boolean primitive wrapper or a boolean primitive.

There are two ways to use this class:

1. When using the com.sleepycat.db 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.

entryToObject

public java.lang.Boolean 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.Boolean>

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.Boolean 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.Boolean>

Parameters:

object - is the key or data object.

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

entryToBoolean

public static boolean entryToBoolean(DatabaseEntry entry)

Converts an entry buffer into a simple boolean value.

Parameters:

entry - is the source entry buffer.

Returns:

the resulting value.

booleanToEntry

public static void booleanToEntry(boolean val,
                                  DatabaseEntry entry)

Converts a simple boolean value into an entry buffer.

Parameters:

val - is the source value.

entry - is the destination entry buffer.
