public class XMLDTDScannerImpl
extends XMLScanner
implements XMLDTDScanner, XMLComponent, XMLEntityHandler

This class is responsible for scanning the declarations found in the internal and external subsets of a DTD in an XML document. The scanner acts as the sources for the DTD information which is communicated to the DTD handlers.

This component requires the following features and properties from the component manager that uses it:

• http://xml.org/sax/features/validation
• http://apache.org/xml/features/scanner/notify-char-refs
• http://apache.org/xml/properties/internal/symbol-table
• http://apache.org/xml/properties/internal/error-reporter
• http://apache.org/xml/properties/internal/entity-manager

Method Detail

setInputSource

public void setInputSource(XMLInputSource inputSource)
                    throws IOException

Deprecated.

Sets the input source.

Specified by:

setInputSource in interface XMLDTDScanner

Parameters:

inputSource - The input source or null.

Throws:

IOException - Thrown on i/o error.

scanDTDExternalSubset

public boolean scanDTDExternalSubset(boolean complete)
                              throws IOException,
                                     XNIException

Deprecated.

Scans the external subset of the document.

Specified by:

scanDTDExternalSubset in interface XMLDTDScanner

Parameters:

complete - True if the scanner should scan the document completely, pushing all events to the registered document handler. A value of false indicates that that the scanner should only scan the next portion of the document and return. A scanner instance is permitted to completely scan a document if it does not support this "pull" scanning model.

Throws:

IOException

XNIException

scanDTDInternalSubset

public boolean scanDTDInternalSubset(boolean complete,
                                     boolean standalone,
                                     boolean hasExternalSubset)

                                     XNIException

Deprecated.

Scans the internal subset of the document.

Specified by:

scanDTDInternalSubset in interface XMLDTDScanner

Parameters:

complete - True if the scanner should scan the document completely, pushing all events to the registered document handler. A value of false indicates that that the scanner should only scan the next portion of the document and return. A scanner instance is permitted to completely scan a document if it does not support this "pull" scanning model.

standalone - True if the document was specified as standalone. This value is important for verifying certain well-formedness constraints.

hasExternalDTD - True if the document has an external DTD. This allows the scanner to properly notify the handler of the end of the DTD in the absence of an external subset.

Throws:

IOException

XNIException
