Class SLObject

java.lang.Object

com.oracle.truffle.api.object.DynamicObject

com.oracle.truffle.sl.runtime.SLObject

All Implemented Interfaces:

com.oracle.truffle.api.interop.TruffleObject

public final class SLObject
extends com.oracle.truffle.api.object.DynamicObject
implements com.oracle.truffle.api.interop.TruffleObject

Represents an SL object. This class defines operations that can be performed on SL Objects. While we could define all these operations as individual AST nodes, we opted to define those operations by using a Truffle library, or more concretely the InteropLibrary. This has several advantages, but the primary one is that it allows SL objects to be used in the interoperability message protocol, i.e. It allows other languages and tools to operate on SL objects without necessarily knowing they are SL objects. SL Objects are essentially instances of DynamicObject (objects whose members can be dynamically added and removed). We also annotate the class with ExportLibrary with value InteropLibrary.class. This essentially ensures that the build system and runtime know that this class specifies the interop messages (i.e. operations) that SL can do on SLObject instances.
