External Interface

The external interface to DataPool is based on Viz messages sent to the DataPool plugin. Each message contains a series of data assignments to different DataFields.

The structure of the message is:

command1 command2 command3 ...

The structure of each command is as follows:

<Name>[items range] = datum1, datum2, datum3, ...;

Where name is the name of the DataField to assign data to and items range is a description of items to which the data is addressed.

Note: The semicolon is part of the command and should be added at all times. It is used to define the end of the command.

The "item ranges" is a comma-separated list of indexes, or a "from-to" index.

Examples

Send data to a field named VALUE:
```
VALUE=30; 
```
Send data to the first 5 values of a field called VALUES:
```
VALUES[0-4] = 0, 1, 2, 3, 4; 
```
The above is equivalent to sending:
```
VALUES[0]=0; VALUES[1]=1; VALUES[2]=2; VALUES[3]=3; VALUES[4]=4; 
```
Note: The indexes of the items are zero-based (start from 0).

Send data to the items 1-3, 55-57 and 101:

VALUES[1-3,55-57, 101] = 0, 1, 2, 3, 4, 5, 6;

This is equivalent to sending:

VALUES[1]=0; VALUES[2]=1; VALUES[3]=2; VALUES[55]=3; VALUES[56]=4; VALUES[57]=5; VALUES[101]=6;
