Class AtomContext

java.lang.Object

brown.tracingplane.impl.AtomContext

All Implemented Interfaces:

BaggageContext

public class AtomContext
extends java.lang.Object
implements BaggageContext

A minimal implementation of BaggageContext based on atoms and lexicographic merge, but providing no read or write methods to the atoms themselves.

Method Summary

Modifier and Type	Method and Description
AtomContext	branch()
java.util.List<java.nio.ByteBuffer>	getModifiableAtoms() Returns the List that backs this AtomContext object, so modifications to the list will be reflected by this context and vice versa.
java.util.List<java.nio.ByteBuffer>	getUnmodifiableAtoms() Returns the List that backs this AtomContext object.
AtomContext	merge(AtomContext other)
int	serializedSize()

Method Detail

branch

public AtomContext branch()

merge

public AtomContext merge(AtomContext other)

serializedSize

public int serializedSize()

getUnmodifiableAtoms

public java.util.List<java.nio.ByteBuffer> getUnmodifiableAtoms()

Returns the List that backs this AtomContext object. This method is only for observing the atoms, not for updating them.

Returns:

the atoms of this AtomContext

getModifiableAtoms

public java.util.List<java.nio.ByteBuffer> getModifiableAtoms()

Returns the List that backs this AtomContext object, so modifications to the list will be reflected by this context and vice versa. AtomContext uses reference counting as an optimization, so a call to this method might result in duplicating atoms if others currently hold a reference to them.

Returns:

the atoms of this AtomContext
