Constructor Summary

protected	DocType() Default, no-args constructor for implementations to use if needed.
	DocType(java.lang.String elementName) This will create the DocType with the specified element name
	DocType(java.lang.String elementName, java.lang.String systemID) This will create the DocType with the specified element name and reference to an external DTD.
	DocType(java.lang.String elementName, java.lang.String publicID, java.lang.String systemID) This will create the DocType with the specified element name and a reference to an external DTD.

Method Summary

DocType	clone() Returns a deep, unattached copy of this child and its descendants detached from any parent or document.
DocType	detach() Detaches this child from its parent or does nothing if the child has no parent.
java.lang.String	getElementName() This will retrieve the element name being constrained.
java.lang.String	getInternalSubset() This returns the data for the internal subset.
Document	getParent() Return this child's parent, or null if this child is currently not attached.
java.lang.String	getPublicID() This will retrieve the public ID of an externally referenced DTD, or an empty String if none is referenced.
java.lang.String	getSystemID() This will retrieve the system ID of an externally referenced DTD, or an empty String if none is referenced.
java.lang.String	getValue() Returns the empty string since doctypes don't have an XPath 1.0 string value.
DocType	setElementName(java.lang.String elementName) This will set the root element name declared by this DOCTYPE declaration.
void	setInternalSubset(java.lang.String newData) This sets the data for the internal subset.

Constructor Detail

DocType

protected DocType()

Default, no-args constructor for implementations to use if needed.

DocType

public DocType(java.lang.String elementName,
               java.lang.String publicID,
               java.lang.String systemID)

This will create the DocType with the specified element name and a reference to an external DTD.

Parameters:

elementName - String name of element being constrained.

publicID - String public ID of referenced DTD

systemID - String system ID of referenced DTD

Throws:

IllegalDataException - if the given system ID is not a legal system literal or the public ID is not a legal public ID.

IllegalNameException - if the given root element name is not a legal XML element name.

DocType

public DocType(java.lang.String elementName,
               java.lang.String systemID)

This will create the DocType with the specified element name and reference to an external DTD.

Parameters:

elementName - String name of element being constrained.

systemID - String system ID of referenced DTD

Throws:

IllegalDataException - if the given system ID is not a legal system literal.

IllegalNameException - if the given root element name is not a legal XML element name.

DocType

public DocType(java.lang.String elementName)

This will create the DocType with the specified element name

Parameters:
