PDComm.GemReportBinding

Class

Represents a binding from a report variable ID (VID) to the source of its value.

public sealed record GemReportBinding

Different VIDs can bind to the same source, but each VID can appear only once. Nonnegative signed and unsigned constant IDs compare equal.

Parameters

Name	Description
Vid	The variable ID (VID) used in report definitions.
SourceKind	The kind of value source.
SourceId	The status variable ID or data variable ID; must be 0 for GemDataSourceKind.Constant.
ConstantId	For GemDataSourceKind.Constant, the equipment constant ID (ECID) as an ASCII item or a single-element integer item; otherwise null. The configuring call copies the item; the caller keeps ownership.
