Usage

1. Copy the script code onto a file resource with "recJs" ending or use the impulse record examples.
2. Open the impulse viewer with the file resource (e.g. double-click the file in the eclipse explorer).

Script

The script create a struct, an integer and a float array signal. Additionally a plot template is added.

//-recjs (keep this line)
// generator   : Record generator (de.toem.impulse.samples.ISingleDomainRecordGenerator)
// file        : File object of the executed recJs file (java.io.File)
// p0..p9      : Parameters from the reader configuration (java.lang.String)
// progress    : Progress control (de.toem.impulse.cells.ports.IPortProgress)
// console     : Console output (de.toem.impulse.scripting.IScriptConsole)
 
// Init the record
