Class AssignExpressionToSymbol

java.lang.Object

org.ek9lang.compiler.phase7.generator.AbstractGenerator

org.ek9lang.compiler.phase7.generator.AssignExpressionToSymbol

All Implemented Interfaces:

BiFunction<ISymbol, EK9Parser.AssignmentExpressionContext, List<IRInstr>>

final class AssignExpressionToSymbol
extends AbstractGenerator
implements BiFunction<ISymbol, EK9Parser.AssignmentExpressionContext, List<IRInstr>>

THE assignment of an assignmentExpression to a symbol (the expression is generated by generators.assignmentExprGenerator), in one of two AssignExpressionToSymbol.Modes - TWO per construct on the set, generators.assignToNewSymbol and generators.assignToExistingSymbol (IR tidy W3.9, EXPR-15), never one per assignment.
