Class ProcessWhileControlVariable

java.lang.Object

org.ek9lang.compiler.common.RuleSupport

org.ek9lang.compiler.common.TypedSymbolAccess

org.ek9lang.compiler.phase3.ProcessWhileControlVariable

All Implemented Interfaces:

Consumer<EK9Parser.WhileStatementExpressionContext>

final class ProcessWhileControlVariable
extends TypedSymbolAccess
implements Consumer<EK9Parser.WhileStatementExpressionContext>

Deals with checking the 'while' or 'do/while control variable in the statement/expression. There is a check on an identifier for 'IdentifierAssignmentOrError' an assignment. This resets the 'referenced' flag on the variable. So for loop variables we must make a note that this is a loop variable to stop this resetting. Otherwise, it looks like the variable is not checked 'after' assignment.
