Example 1 with Serializer

use of org.reflections.serializers.Serializer in project reflections by ronmamo.

the class Reflections method collect.

/**
     * collect saved Reflections resources from all urls that contains the given packagePrefix and matches the given resourceNameFilter
     * and de-serializes them using the default serializer {@link org.reflections.serializers.XmlSerializer} or using the optionally supplied optionalSerializer
     * <p>
     * it is preferred to use a designated resource prefix (for example META-INF/reflections but not just META-INF),
     * so that relevant urls could be found much faster
     * @param optionalSerializer - optionally supply one serializer instance. if not specified or null, {@link org.reflections.serializers.XmlSerializer} will be used
