Method Details
-
dispatch
Dispatch an XML "event".- Specified by:
dispatch
in interfaceXMLDocumentFragmentScannerImpl.Dispatcher
- Parameters:
complete
- True if this dispatcher is intended to scan and dispatch as much as possible.- Returns:
- True if there is more to dispatch either from this or a another dispatcher.
- Throws:
IOException
- Thrown on i/o error.org.apache.xerces.xni.XNIException
- Thrown on parse error.
-
scanForDoctypeHook
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 "invalid input: '<!'" has been scanned.- Returns:
- True if the "DOCTYPE" was scanned; false if "DOCTYPE" was not scanned.
- Throws:
IOException
org.apache.xerces.xni.XNIException
-
elementDepthIsZeroHook
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.- 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:
IOException
org.apache.xerces.xni.XNIException
-
scanRootElementHook
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.- 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:
IOException
org.apache.xerces.xni.XNIException
-
endOfFileHook
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.- Throws:
IOException
org.apache.xerces.xni.XNIException
