Class EventAllocatorImpl

  • All Implemented Interfaces:
    javax.xml.stream.util.XMLEventAllocator, javax.xml.stream.XMLStreamConstants
    public final class EventAllocatorImpl
extends org.codehaus.stax2.ri.evt.Stax2EventAllocatorImpl
    Specialized event allocator implementation. Beyond additions needed to support DTD entities, implements non-location-preserving optimization.

      protected javax.xml.stream.Location getLocation​(javax.xml.stream.XMLStreamReader r)
      Method used to get the Location object to use for an event to create.
      javax.xml.stream.util.XMLEventAllocator newInstance()
      Default implementation assumes that the caller knows how to share instances, and so need not create new copies.

      • _cfgPreserveLocation

        protected final boolean _cfgPreserveLocation

      • _lastLocation

        protected javax.xml.stream.Location _lastLocation
        Last used location info; only relevant to non-accurate-location allocators.

    • Constructor Detail

      • EventAllocatorImpl

        protected EventAllocatorImpl​(boolean preserveLocation)
        Parameters:
        preserveLocation - If true, allocator will construct instances that have accurate location information; if false, instances will only have some generic shared Location info. Latter option will reduce memory usage/thrashing a bit, and may improve speed.

    • Method Detail

      • newInstance

        public javax.xml.stream.util.XMLEventAllocator newInstance()
        Default implementation assumes that the caller knows how to share instances, and so need not create new copies.

        Note: if this class is sub-classes, this method should be redefined if assumptions about shareability do not hold.

        Specified by:
        newInstance in interface javax.xml.stream.util.XMLEventAllocator
        Overrides:
        newInstance in class org.codehaus.stax2.ri.evt.Stax2EventAllocatorImpl

      • allocate

        public javax.xml.stream.events.XMLEvent allocate​(javax.xml.stream.XMLStreamReader r)
                                          throws javax.xml.stream.XMLStreamException
        Specified by:
        allocate in interface javax.xml.stream.util.XMLEventAllocator
        Overrides:
        allocate in class org.codehaus.stax2.ri.evt.Stax2EventAllocatorImpl
        Throws:
        javax.xml.stream.XMLStreamException

      • getLocation

        protected javax.xml.stream.Location getLocation​(javax.xml.stream.XMLStreamReader r)
        Method used to get the Location object to use for an event to create. Base implementation just calls stream reader's accessors, but sub-classes may choose to use other methods (esp. when not in "preserve location" mode).
        Overrides:
        getLocation in class org.codehaus.stax2.ri.evt.Stax2EventAllocatorImpl
