Class ByteBufTuple

java.lang.Object

org.thales.punch.libraries.punchlang.impl.AbstractTupleImpl

org.thales.punch.libraries.punchlang.impl.TupleImpl

org.thales.punch.libraries.punchlang.resource.tuple.ByteBufTuple

All Implemented Interfaces:

Comparable<Tuple>, Tuple, IResourceTuple

public class ByteBufTuple
extends TupleImpl
implements IResourceTuple

This is the most efficient implementation. A single buffer is used using direct memory. Only offsets are kept for later lazy retrieval.

ByteBufTuple

public ByteBufTuple()

Method Detail

getStringFromByteBuf

protected String getStringFromByteBuf(String key)

set

public Tuple set(Object value)

Description copied from class: TupleImpl

Set a new value to a tuple

Specified by:

set in interface Tuple

Overrides:

set in class TupleImpl

Parameters:

value - the value to set

Returns:

this tuple

addKeyValue

public void addKeyValue(String key,
                        Tuple item)

Description copied from interface: IResourceTuple

Set or reset a value in a resource tuple

Specified by:

addKeyValue in interface IResourceTuple

onEnd

public Tuple onEnd()

Description copied from interface: IResourceTuple

This signal tells you the loading of a remote resource is now terminated. Do whatever you need to do to clean up your structures.

You must return the underlying Tuple resource object.

Specified by:

onEnd in interface IResourceTuple

Returns:

the underlying resource tuple implementation

isEmpty

public boolean isEmpty()

Description copied from interface: Tuple

Check if a tuple contains some value.

Specified by:

isEmpty in interface Tuple

Overrides:

isEmpty in class TupleImpl

Returns:

true if the tuple contains a leaf, map, set or array.

get

public Tuple get(String key)

Description copied from class: TupleImpl

Retrieve a child. If the child node does not exists, an empty one is returned. The rationale is to allow executing:

   tuple.get("a").get("b|).get("c").set("hello");
 

Without 'a' being there.

Specified by:

get in interface Tuple

Overrides:

get in class TupleImpl

Parameters:

key - the target value key

Returns:

the child tuple
