Projector

com.ossuminc.riddl.language.AST.Projector
case class Projector(loc: At, id: Identifier, contents: ArrayBuffer[ProjectorContents], metadata: ArrayBuffer[MetaData]) extends Processor[ProjectorContents], WithOptions[ProjectorContents]

Projectors get their name from Euclidean Geometry but are probably more analogous to a relational database view. The concept is very simple in RIDDL: projectors gather data from entities and other sources, transform that data into a specific record type, and support querying that data arbitrarily.

Value parameters

contents

The content of this Projectors' definition

id

The unique identifier for this Projector

loc

Location in the source of the Projector
