## Class DOMImplementationImpl

- java.lang.Object
- - org.apache.xerces.dom.CoreDOMImplementationImpl
  - - org.apache.xerces.dom.DOMImplementationImpl

- All Implemented Interfaces:
    org.w3c.dom.DOMImplementation, org.w3c.dom.ls.DOMImplementationLS
  Direct Known Subclasses:
    ASDOMImplementationImpl, DeferredDOMImplementationImpl, PSVIDOMImplementationImpl

      public class DOMImplementationImpl
      extends CoreDOMImplementationImpl
      implements org.w3c.dom.DOMImplementation

  The DOMImplementation class is description of a particular implementation of the Document Object Model. As such its data is static, shared by all instances of this implementation.

  The DOM API requires that it be a real object rather than static methods. However, there's nothing that says it can't be a singleton, so that's how I've implemented it.

  Since:
    PR-DOM-Level-1-19980818.

- - ### Constructor Detail

    - #### DOMImplementationImpl

          public DOMImplementationImpl()

  - ### Method Detail

    - #### getDOMImplementation

          public static org.w3c.dom.DOMImplementation getDOMImplementation()

      NON-DOM: Obtain and return the single shared object

    - #### hasFeature

          public boolean hasFeature(java.lang.String feature,
                           java.lang.String version)

      Test if the DOM implementation supports a specific "feature" -- currently meaning language and level thereof.
      Specified by:
        `hasFeature` in interface `org.w3c.dom.DOMImplementation`
      Overrides:
        `hasFeature` in class `CoreDOMImplementationImpl`
      Parameters:
        `feature` - The package name of the feature to test. In Level 1, supported values are "HTML" and "XML" (case-insensitive). At this writing, org.apache.xerces.dom supports only XML.
        `version` - The version number of the feature being tested. This is interpreted as "Version of the DOM API supported for the specified Feature", and in Level 1 should be "1.0"
      Returns:
        true iff this implementation is compatable with the specified feature and version.

    - #### createDocument

          protected CoreDocumentImpl createDocument(org.w3c.dom.DocumentType doctype)

      Overrides:
        `createDocument` in class `CoreDOMImplementationImpl`
