Examples with PageActivationContextWorker org.apache.tapestry5.internal.transform.PageActivationContextWorker used on opensource projects

Example 1 with PageActivationContextWorker

use of org.apache.tapestry5.internal.transform.PageActivationContextWorker in project tapestry-5 by apache.

the class PageActivationContextWorker method transformFields.

private void transformFields(TransformationSupport support, List<PlasticField> fields) {
    List<PlasticField> sortedFields = CollectionFactory.newList(fields);
    Collections.sort(sortedFields, INDEX_COMPARATOR);
    validateSortedFields(sortedFields);
    PlasticField firstField = sortedFields.get(0);
    PageActivationContext firstAnnotation = firstField.getAnnotation(PageActivationContext.class);
    // these arrays reduce memory usage and allow the PlasticField instances to be garbage collected
    FieldHandle[] handles = new FieldHandle[sortedFields.size()];
    String[] typeNames = new String[sortedFields.size()];
    int i = 0;
    for (PlasticField field : sortedFields) {
        handles[i] = field.getHandle();
        typeNames[i] = field.getTypeName();
        ++i;
    }
    if (firstAnnotation.activate()) {
        support.addEventHandler(EventConstants.ACTIVATE, 1, "PageActivationContextWorker activate event handler", createActivationHandler(handles, typeNames));
    }
    if (firstAnnotation.passivate()) {
        support.addEventHandler(EventConstants.PASSIVATE, 0, "PageActivationContextWorker passivate event handler", createPassivateHandler(handles));
    }
// We don't claim the field, and other workers may even replace it with a FieldConduit.
}
