org.ek9lang.compiler.phase3.SymbolFromContextOrError

All Implemented Interfaces:

Function<org.antlr.v4.runtime.ParserRuleContext,ISymbol>

final class SymbolFromContextOrError
extends TypedSymbolAccess
implements Function<org.antlr.v4.runtime.ParserRuleContext,ISymbol>

Returns the appropriate symbol from the symbol and scope management component. But if it is null issues a semantic error. Not this is not looking up through scopes or anything, just looking directly as what symbol (if any) has been recorded against the context passed in.
