ConnectionStringTable Class Reference

#include <connectionStringTable.h>

Detailed Description

Maintain a table of strings which are shared across the network.

This allows us to reference strings in our network streams more efficiently.

Public Types

enum Constants {
  EntryCount = 32,
  EntryBitSize = 5,
  InvalidEntryId = 32
}

Public Member Functions

ConnectionStringTable (NetConnection *parent)

Initialize the connection string table.

void confirmStringReceived (StringHandle &string, U32 index)

Has the specified string been received on the other side?

U32 checkString (StringHandle &stringTableId, bool *stringOnOtherSide=NULL)

Checks if the global string ID is currently valid for this connection and returns the table ID.

U32 getNetSendId (StringHandle &stringTableId)

Same return value as checkString but will assert if the string is not valid.

void mapString (U32 netId, StringHandle &string)

Maps a string that was just sent over the net to the corresponding net ID.

StringHandle lookupString (U32 netId)

Demo functionality

void readDemoStartBlock (BitStream *stream)

void writeDemoStartBlock (ResizeBitStream *stream)

Private Member Functions

void pushBack (Entry *entry)

Private Attributes

Entry mEntryTable [EntryCount]

Entry * mHashTable [EntryCount]

StringHandle mRemoteStringTable [EntryCount]

Entry mLRUHead

Entry mLRUTail

NetConnection * mParent

Connection over which we are maintaining this string table.

Data Structures

struct Entry

Enumerator:

ConnectionStringTable::ConnectionStringTable ( NetConnection * parent )

Initialize the connection string table.

Parameters:

parent

Connection over which we are maintaining this string table.

void ConnectionStringTable::pushBack ( Entry * entry ) [inline, private]

void ConnectionStringTable::confirmStringReceived	(	StringHandle &	string,
		U32	index
	)			`[inline]`

Has the specified string been received on the other side?

U32 ConnectionStringTable::checkString	(	StringHandle &	stringTableId,
		bool *	stringOnOtherSide = `NULL`
	)

Checks if the global string ID is currently valid for this connection and returns the table ID.

Sends a string event to the other side if it is not active. It will fill in stringOnOtherSide.

U32 ConnectionStringTable::getNetSendId ( StringHandle & stringTableId )

Same return value as checkString but will assert if the string is not valid.

void ConnectionStringTable::mapString	(	U32	netId,
		StringHandle &	string
	)

Maps a string that was just sent over the net to the corresponding net ID.

StringHandle ConnectionStringTable::lookupString ( U32 netId ) [inline]

the global string table ID for that string.

Parameters:

netId

looks up the string ID and returns

void ConnectionStringTable::readDemoStartBlock ( BitStream * stream )

void ConnectionStringTable::writeDemoStartBlock ( ResizeBitStream * stream )

Connection over which we are maintaining this string table.
