Example 46 with Iterator

use of java.util.Iterator in project groovy-core by groovy.

the class StatementWriter method writeSwitch.

public void writeSwitch(SwitchStatement statement) {
    controller.getAcg().onLineNumber(statement, "visitSwitch");
    writeStatementLabel(statement);
    statement.getExpression().visit(controller.getAcg());
    // switch does not have a continue label. use its parent's for continue
    Label breakLabel = controller.getCompileStack().pushSwitch();
    int switchVariableIndex = controller.getCompileStack().defineTemporaryVariable("switch", true);
    List caseStatements = statement.getCaseStatements();
    int caseCount = caseStatements.size();
    Label[] labels = new Label[caseCount + 1];
    for (int i = 0; i < caseCount; i++) {
        labels[i] = new Label();
    }
    int i = 0;
    for (Iterator iter = caseStatements.iterator(); iter.hasNext(); i++) {
        CaseStatement caseStatement = (CaseStatement) iter.next();
        writeCaseStatement(caseStatement, switchVariableIndex, labels[i], labels[i + 1]);
