Method Detail

getDocument

public Document getDocument(File filename,
                   boolean validate)
                     throws IOException,
                            JDOMException

This creates a new Document from an existing InputStream by letting a DOM parser handle parsing using the supplied stream.

Specified by:

getDocument in interface DOMAdapter

Parameters:

filename - file to parse.

validate - boolean to indicate if validation should occur.

Returns:

Document - instance ready for use.

Throws:

IOException - when I/O error occurs.

JDOMException - when errors occur in parsing.

getDocument

public abstract Document getDocument(InputStream in,
                   boolean validate)
                              throws IOException,
                                     JDOMException

This creates a new Document from an existing InputStream by letting a DOM parser handle parsing using the supplied stream.

Specified by:

getDocument in interface DOMAdapter

Parameters:

in - InputStream to parse.

validate - boolean to indicate if validation should occur.

Returns:

Document - instance ready for use.

Throws:

IOException - when I/O error occurs.

JDOMException - when errors occur in parsing.

createDocument

public abstract Document createDocument()
                                 throws JDOMException

This creates an empty Document object based on a specific parser implementation.

Specified by:

createDocument in interface DOMAdapter

Returns:

Document - created DOM Document.

Throws:

JDOMException - when errors occur.

createDocument

public Document createDocument(DocType doctype)
                        throws JDOMException

This creates an empty Document object based on a specific parser implementation with the given DOCTYPE. If the doctype parameter is null, the behavior is the same as calling createDocument().

Specified by:

createDocument in interface DOMAdapter

Parameters:

doctype - Initial DocType of the document.

Returns:

Document - created DOM Document.

Throws:

JDOMException - when errors occur.

setInternalSubset

protected void setInternalSubset(DocumentType dt,
                     String s)

This attempts to change the DocumentType to have the given internal DTD subset value. This is not a standard ability in DOM, so it's only available with some parsers. Subclasses can alter the mechanism by which the attempt is made to set the value.

Parameters:

dt - DocumentType to be altered

s - String to use as the internal DTD subset
