sDtdName - the name of the DTD (public identifier); may be null

Method Detail

getDtdUri

public java.lang.String getDtdUri()

Specified by:

getDtdUri in interface XmlDocument

Returns:

the document type URI

setDtdUri

public void setDtdUri(java.lang.String sUri)

Set the URI of the DTD (DOCTYPE) for the document. This is referred to as the System Identifier by the XML specification.

setDtdUri in interface XmlDocument

Parameters:

sUri - the document type URI

getDtdName

public java.lang.String getDtdName()

Get the public identifier of the DTD (DOCTYPE) for the document. For example: -//Sun Microsystems, Inc.//DTD Web Application 1.2//EN

Specified by:

getDtdName in interface XmlDocument

Returns:

the encoding set for the document

setEncoding

public void setEncoding(java.lang.String sEncoding)

Set the encoding string for the XML document.

Specified by:

setEncoding in interface XmlDocument

Parameters:

sEncoding - the encoding that the document will use

getDocumentComment

public java.lang.String getDocumentComment()

Get the XML comment that appears outside of the root element. This differs from the Comment property of this object, which refers to the comment within the root element.

Specified by:

getDocumentComment in interface XmlDocument

Returns:

the document comment

setDocumentComment

public void setDocumentComment(java.lang.String sComment)

Set the XML comment that appears outside of the root element. This differs from the Comment property of this object, which refers to the comment within the root element.

Specified by:

setDocumentComment in interface XmlDocument

Parameters:

sComment - the document comment

writeXml

public void writeXml(java.io.PrintWriter out,
                     boolean fPretty)

Parameters:

out - a PrintWriter object to use to write to

fPretty - true to specify that the output is intended to be as human readable as possible

hashCode

public int hashCode()

Provide a hash value for this XML document and all of its contained information. Note that this overrides the contract of the hashCode method in the super interface XmlElement. The hash value is defined as a xor of the following:
