## Detailed Description

The TQDomDocumentType class is the representation of the DTD in the document tree.

The TQDomDocumentType class allows read-only access to some of the data structures in the DTD: it can return a map of all entities() and notations(). In addition the function name() returns the name of the document type as specified in the <!DOCTYPE name> tag. This class also provides the publicId(), systemId() and internalSubset() functions.

See also TQDomDocument and XML.

## Member Function Documentation

### TQDomDocumentType::TQDomDocumentType ()

Creates an empty TQDomDocumentType object.

### TQDomDocumentType::TQDomDocumentType ( const TQDomDocumentType & n )

Constructs a copy of n.

The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().

### TQDomDocumentType::~TQDomDocumentType ()

Destroys the object and frees its resources.

### TQDomNamedNodeMap TQDomDocumentType::entities () const`[virtual]`

Returns a map of all entities described in the DTD.

### TQString TQDomDocumentType::internalSubset () const`[virtual]`

Returns the internal subset of the document type or TQString::null if there is no internal subset.

See also publicId() and systemId().

### bool TQDomDocumentType::isDocumentType () const`[virtual]`

This function overloads TQDomNode::isDocumentType().

See also nodeType() and TQDomNode::toDocumentType().

Reimplemented from TQDomNode.

### TQString TQDomDocumentType::name () const`[virtual]`

Returns the name of the document type as specified in the <!DOCTYPE name> tag.

See also nodeName().

### TQDomNode::NodeType TQDomDocumentType::nodeType () const`[virtual]`

Returns DocumentTypeNode.

See also isDocumentType() and TQDomNode::toDocumentType().

Reimplemented from TQDomNode.

### TQDomNamedNodeMap TQDomDocumentType::notations () const`[virtual]`

Returns a map of all notations described in the DTD.

### TQDomDocumentType & TQDomDocumentType::operator= ( const TQDomDocumentType & n )

Assigns n to this document type.

The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().

### TQString TQDomDocumentType::publicId () const`[virtual]`

Returns the public identifier of the external DTD subset or TQString::null if there is no public identifier.

See also systemId(), internalSubset(), and TQDomImplementation::createDocumentType().

### TQString TQDomDocumentType::systemId () const`[virtual]`

Returns the system identifier of the external DTD subset or TQString::null if there is no system identifier.

See also publicId(), internalSubset(), and TQDomImplementation::createDocumentType().
