Class LhsFromPreFlowOrError

java.lang.Object

org.ek9lang.compiler.common.RuleSupport

org.ek9lang.compiler.common.TypedSymbolAccess

org.ek9lang.compiler.common.LhsFromPreFlowOrError

All Implemented Interfaces:

Function<EK9Parser.PreFlowStatementContext, ISymbol>

public final class LhsFromPreFlowOrError
extends TypedSymbolAccess
implements Function<EK9Parser.PreFlowStatementContext, ISymbol>

Access the Symbol for the lhs of the preflow statement. i.e. what is the subject of the preflow. This can be a declaration or an assignment.

  preFlowStatement
    : (variableDeclaration | assignmentStatement) (WITH|THEN)?
    ;

While this is in the common package, it does expect symbols to be defined and 'typed'. So use after phase three onwards.
