Introduction

Linksets may store up to 128KiB of data as key/value pairs available to LSL scripts. This data is attached to the root prim in the linkset and survives transfer, script reset and object copying, it does not count against the memory usage of any script. Once set, the only way to erase it is via either the llLinksetDataReset or the llLinksetDataDelete functions. Whenever a script successfully modifies the linkset data using the llLinksetDataReset, llLinksetDataWrite or llLinksetDataCreate functions a linkset_data event is fired in all scripts in the linkset describing the action taken and key name that was affected.

Linkset data is not visible outside of a linkset; a script may only access the linkset data for the linkset that it is running in. Linkset data is not applicable to avatars.

When merging two linksets, both with linkset data, the new root's data is preserved and the simulator makes an effort to move as many of the key value pairs from the old root to the new. If there is insufficient space for all data the simulator will discard some data from the old root. The data selected for preservation may be arbitrary.

Functions

Function: integer llLinksetDataWrite( string name, string value );


0.0	Forced Delay
10.0	Energy

Creates or updates a key/value pair in the linksets datastore.
Returns an integer indicating success or failure. 0 is success, a positive number indicates failure.

• string	name	–	key name for data to be stored.
• string	value	–	String data to be associated with this key.

Caveats

If value is an empty string, the key is deleted from the linkset data.

Function: string llLinksetDataRead( string name );


0.0	Forced Delay
10.0	Energy

Reads the value associated with a key from the linkset's key-value datastore.
Returns a string associated with the key. If the key does not exist, an empty string is returned.

• string

name

–

key name for data to be stored.key name for data to be read.

Function: llLinksetDataDelete( string name );


0.0	Forced Delay
10.0	Energy

Removes a key value pair from the linkset's datastore.

• string

name

–

key name for data to be stored.key name for data to be read.which is the key name for data to be read.

Function: llLinksetDataReset( );


0.0	Forced Delay
10.0	Energy

Erases all existing keys value pairs in the linkset's datastore.

Function: integer llLinksetDataAvailable( );


0.0	Forced Delay
10.0	Energy

The number of bytes available in the linkset's datastore
Returns an integer with the number of bytes free in the datastore.

Function: integer llLinksetDataCountKeys( );


0.0	Forced Delay
10.0	Energy

Returns the number of keys used in the datastore.
Returns an integer with the total number of keys in use.

Function: list llLinksetDataListKeys( integer first, integer count );


0.0	Forced Delay
10.0	Energy

Return a list of keys currently in use in the linkset data.
Returns a list of keys stored in the linkset data.

• integer	first	–	The (zero based) index of the first key to return.
• integer	count	–	The maximum number of key names to return in the list.

Function: list llLinksetDataFindKeys( string regex, integer first, integer count );


0.0	Forced Delay
10.0	Energy

Return a list of keys the linkset data which match the expression passed to the function.
Returns a list of keys matching regex stored in the linkset data.

• string	regex	–	A regex expression to search for.
• integer	first	–	The (zero based) index of the first key to return.The (zero based) index of the first key to return.
• integer	count	–	The maximum number of key names to return in the list.The maximum number of key names to return in the list.

Events

Function: linkset_data( integer action, string name, string value );


	Forced Delay
	Energy

• integer	action	–	The action taken on the linkset datastore. reset, update or delete.
• string	name	–	key name for data to be stored.key name for data to be read.which is the key name for data to be read.The name of key changed. Empty string for reset.
• string	value	–	String data to be associated with this key.The value associated with the key. Empty string for reset or delete.
