      • scanForDoctypeHook

        protected boolean scanForDoctypeHook()
                                      throws java.io.IOException,
                                             org.apache.xerces.xni.XNIException
        Scan for DOCTYPE hook. This method is a hook for subclasses to add code to handle scanning for a the "DOCTYPE" string after the string "
        Overrides:
        scanForDoctypeHook in class XMLDocumentFragmentScannerImpl.FragmentContentDispatcher
        Returns:
        True if the "DOCTYPE" was scanned; false if "DOCTYPE" was not scanned.
        Throws:
        java.io.IOException
        org.apache.xerces.xni.XNIException
      • elementDepthIsZeroHook

        protected boolean elementDepthIsZeroHook()
                                          throws java.io.IOException,
                                                 org.apache.xerces.xni.XNIException
        Element depth iz zero. This methos is a hook for subclasses to add code to handle when the element depth hits zero. When scanning a document fragment, an element depth of zero is normal. However, when scanning a full XML document, the scanner must handle the trailing miscellanous section of the document after the end of the document's root element.
        Overrides:
        elementDepthIsZeroHook in class XMLDocumentFragmentScannerImpl.FragmentContentDispatcher
        Returns:
        True if the caller should stop and return true which allows the scanner to switch to a new scanning dispatcher. A return value of false indicates that the content dispatcher should continue as normal.
        Throws:
        java.io.IOException
        org.apache.xerces.xni.XNIException
      • scanRootElementHook

        protected boolean scanRootElementHook()
                                       throws java.io.IOException,
                                              org.apache.xerces.xni.XNIException
        Scan for root element hook. This method is a hook for subclasses to add code that handles scanning for the root element. When scanning a document fragment, there is no "root" element. However, when scanning a full XML document, the scanner must handle the root element specially.
        Overrides:
        scanRootElementHook in class XMLDocumentFragmentScannerImpl.FragmentContentDispatcher
        Returns:
        True if the caller should stop and return true which allows the scanner to switch to a new scanning dispatcher. A return value of false indicates that the content dispatcher should continue as normal.
        Throws:
        java.io.IOException
        org.apache.xerces.xni.XNIException
      • endOfFileHook

        protected void endOfFileHook​(java.io.EOFException e)
                              throws java.io.IOException,
                                     org.apache.xerces.xni.XNIException
        End of file hook. This method is a hook for subclasses to add code that handles the end of file. The end of file in a document fragment is OK if the markup depth is zero. However, when scanning a full XML document, an end of file is always premature.
        Overrides:
        endOfFileHook in class XMLDocumentFragmentScannerImpl.FragmentContentDispatcher
        Throws:
        java.io.IOException
        org.apache.xerces.xni.XNIException
      • resolveExternalSubsetAndRead

        protected void resolveExternalSubsetAndRead()
                                             throws java.io.IOException,
                                                    org.apache.xerces.xni.XNIException

        Attempt to locate an external subset for a document that does not otherwise have one. If an external subset is located, then it is scanned.

        Throws:
        java.io.IOException
        org.apache.xerces.xni.XNIException
