## com.sleepycat.bind.tuple
Class BooleanBinding

    java.lang.Object
      com.sleepycat.bind.tuple.TupleBinding
          com.sleepycat.bind.tuple.BooleanBinding

All Implemented Interfaces:
  EntryBinding

public class BooleanBinding
extends TupleBinding

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)` method.

Constructor Summary
`BooleanBinding()`

Method Summary
`static void` | `booleanToEntry(boolean val, DatabaseEntry entry)` Converts a simple `boolean` value into an entry buffer.
`static boolean` | `entryToBoolean(DatabaseEntry entry)` Converts an entry buffer into a simple `boolean` value.
`Object` | `entryToObject(TupleInput input)` Constructs a key or data object from a `TupleInput` entry.
`void` | `objectToEntry(Object object, DatabaseEntry entry)` Converts an Object into a entry buffer.
`void` | `objectToEntry(Object object, TupleOutput output)` Converts a key or data object to a tuple entry.

Method Detail

### entryToObject

    public Object entryToObject(TupleInput input)

  Description copied from class: `TupleBinding`
  Constructs a key or data object from a `TupleInput` entry.

  Specified by:
    `entryToObject` in class `TupleBinding`
  Parameters:
    `input` - is the tuple key or data entry.
  Returns:
    the key or data object constructed from the entry.

### objectToEntry

    public void objectToEntry(Object object,
                              TupleOutput output)

  Description copied from class: `TupleBinding`
  Converts a key or data object to a tuple entry.

  Specified by:
    `objectToEntry` in class `TupleBinding`
  Parameters:
    `object` - is the key or data object.
    `output` - is the tuple entry to which the key or data should be written.

### objectToEntry

    public void objectToEntry(Object object,
                              DatabaseEntry entry)

  Description copied from interface: `EntryBinding`
  Converts an Object into a entry buffer.

  Specified by:
    `objectToEntry` in interface `EntryBinding`
  Overrides:
    `objectToEntry` in class `TupleBinding`

### 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.
