Interface XMLDTDScanner
- All Superinterfaces:
- XMLDTDContentModelSource, XMLDTDSource
- public interface XMLDTDScanner
- extends XMLDTDSource, XMLDTDContentModelSource
This interface defines a generic DTD scanner. This interface
allows a scanner to be used interchangably in existing parser
configurations.
If the parser configuration uses a DTD scanner that implements
this interface, components should be able to query the scanner
instance from the component manager using the following property
identifier:
"http://apache.org/xml/properties/internal/dtd-scanner"

setInputSource
public void setInputSource(XMLInputSource inputSource)
throws java.io.IOException

- Thrown on i/o error.
scanDTDInternalSubset
public boolean scanDTDInternalSubset(boolean complete,
boolean standalone,
boolean hasExternalSubset)
throws java.io.IOException,
XNIException
- Scans the internal subset of the document.
- 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.hasExternalSubset
- 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.- Returns:
- True if there is more to scan, false otherwise.
scanDTDExternalSubset
public boolean scanDTDExternalSubset(boolean complete)
throws java.io.IOException,
XNIException
- Scans the external subset of the document.
- 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.- Returns:
- True if there is more to scan, false otherwise.
