Field Detail

runnableQueue

protected RunnableQueue runnableQueue
The RunnableQueue which runs the method calls.

domImplementation

protected DOMImplementation domImplementation
The wrapped DOMImplementation object.
Constructor Detail

DOMImplementationWrapper

public DOMImplementationWrapper(RunnableQueue rq,
                                DOMImplementation di)
Creates a new DOMImplementationWrapper associated with the given RunnableQueue thread.
Method Detail

hasFeature

public boolean hasFeature(java.lang.String feature,
                          java.lang.String version)
DOM: Implements DOMImplementation.hasFeature(String,String).
Specified by:
hasFeature in interface DOMImplementation
Following copied from interface: org.w3c.dom.DOMImplementation
Parameters:
featureThe - name of the feature to test (case-insensitive). The values used by DOM features are defined throughout the DOM Level 2 specifications and listed in the section. The name must be an XML name. To avoid possible conflicts, as a convention, names referring to features defined outside the DOM specification should be made unique by reversing the name of the Internet domain name of the person (or the organization that the person belongs to) who defines the feature, component by component, and using this as a prefix. For instance, the W3C SVG Working Group defines the feature "org.w3c.dom.svg".
versionThis - is the version number of the feature to test. In Level 2, the string can be either "2.0" or "1.0". If the version is not specified, supporting any version of the feature causes the method to return true.
Returns:
true if the feature is implemented in the specified version, false otherwise.

createDocumentType

public DocumentType createDocumentType(java.lang.String qualifiedName,
                                       java.lang.String publicId,
                                       java.lang.String systemId)
                                throws DOMException
DOM: Implements DOMImplementation.createDocumentType(String,String,String).
Specified by:
createDocumentType in interface DOMImplementation
Following copied from interface: org.w3c.dom.DOMImplementation
Parameters:
qualifiedNameThe - qualified name of the document type to be created.
publicIdThe - external subset public identifier.
systemIdThe - external subset system identifier.
Returns:
A new DocumentType node with Node.ownerDocument set to null.
Throws:
DOMException - INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character.
NAMESPACE_ERR: Raised if the qualifiedName is malformed.

createDocument

public Document createDocument(java.lang.String nsURI,
                               java.lang.String qName,
                               DocumentType doctype)
                        throws DOMException
DOM: Implements DOMImplementation.createDocument(String,String,DocumentType).
Specified by:
createDocument in interface DOMImplementation
Following copied from interface: org.w3c.dom.DOMImplementation
Parameters:
namespaceURIThe - namespace URI of the document element to create.
qualifiedNameThe - qualified name of the document element to be created.
doctypeThe - type of document to be created or null. When doctype is not null, its Node.ownerDocument attribute is set to the document being created.
Returns:
A new Document object.
Throws:
DOMException - INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character.
NAMESPACE_ERR: Raised if the qualifiedName is malformed, if the qualifiedName has a prefix and the namespaceURI is null, or if the qualifiedName has a prefix that is "xml" and the namespaceURI is different from " http://www.w3.org/XML/1998/namespace" .
WRONG_DOCUMENT_ERR: Raised if doctype has already been used with a different document or was created from a different implementation.

createEventWrapper

public Event createEventWrapper(DocumentWrapper dw,
                                Event ev)
                         throws DOMException
Creates an EventWrapper object.

invokeAndWait

protected void invokeAndWait(java.lang.Runnable r)
Invokes the given Runnable from the associated RunnableQueue thread.

invokeLater

protected void invokeLater(java.lang.Runnable r)
Invokes the given Runnable from the associated RunnableQueue thread.
