All Implemented Interfaces:

public final class SLLanguageView
extends Object
implements com.oracle.truffle.api.interop.TruffleObject

Language views are needed in order to allow tools to have a consistent perspective on primitive or foreign values from the perspective of this language. The interop interpretation for primitive values like Integer or String is not language specific by default. Therefore this language view calls routines to print such values the SimpleLanguage way. It is important to note that language views are not passed as normal values through the interpreter execution. It is designed only as a temporary helper for tools.

forValue
