org.eclipse.jpt.common.core.resource.xml
Class JptXmlResource

java.lang.Object
  TranslatorResourceImpl
      org.eclipse.jpt.common.core.resource.xml.JptXmlResource

All Implemented Interfaces:

ContentTypeReference, JptResourceModel, JptResourceTypeReference

public class JptXmlResource
extends TranslatorResourceImpl
implements JptResourceModel, ContentTypeReference

To retrieve the JPA XML resource corresponding to an Eclipse file:

 IFile file = (IFile) ResourcesPlugin.getWorkspace().getRoot().findMember("Foo.java");
 JptXmlResource jpaXmlResource = (JptXmlResource) file.getAdapter(JptXmlResource.class);
 

This is a non-blocking call; and as a result it will return null if the JPA XML resource or its JPA project is currently under construction.

See org.eclipse.jpt.jpa.core/plugin.xml:org.eclipse.core.runtime.adapters.

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

Since:

Field Detail

contentType

protected final IContentType contentType

cache the content type - if the content type changes, the JPA project will throw out the JPA file holding the xml resource and build a new one

rootTranslator

protected final Translator rootTranslator

resourceModelListenerList

protected final org.eclipse.jpt.common.utility.internal.ListenerList<JptResourceModelListener> resourceModelListenerList

Constructor Detail

JptXmlResource

public JptXmlResource(URI uri,
                      Renderer renderer,
                      IContentType contentType,
                      Translator rootTranslator)

Method Detail

getContentType

public IContentType getContentType()

Description copied from interface: ContentTypeReference

Return an Eclipse content type.

Specified by:

getContentType in interface ContentTypeReference

getVersion

public String getVersion()

getResourceType

public JptResourceType getResourceType()

The XML schema version is required.

Specified by:

getResourceType in interface JptResourceTypeReference

getResourceType

protected JptResourceType getResourceType(String version)

eNotify

public void eNotify(Notification notification)

Override to fire notification only when:

• the resource's state has actually changed; and
• the resource is loaded; and
• the resource's resource set is still present (EMF will fire an notification when the resource set is set to 'null', just before the resource is "unloaded" - we want to swallow this notification)

loadedFlagCleared

protected boolean loadedFlagCleared(Notification notification)

Return whether the specified notification indicates the resource has been unloaded. we could use this method to suppress some notifications; or we could just check whether 'resourceSet' is 'null' (which is what we do)

resultSetCleared

protected boolean resultSetCleared(Notification notification)

Return whether the specified notification indicates the resource's resource set was cleared. We could use this method to suppress some resource set notifications; or we could just check whether resourceSet is null (which is what we do)/

getDoctype

public String getDoctype()

only applicable for DTD-based files

getRootTranslator

public Translator getRootTranslator()

getDefaultPublicId

protected String getDefaultPublicId()

only applicable for DTD-based files

getDefaultSystemId

protected String getDefaultSystemId()

only applicable for DTD-based files

getDefaultVersionID

protected int getDefaultVersionID()

this seems to be the default version of the spec for this doc and the id 10 maps to the version 1.0

getRootObject

public org.eclipse.jpt.common.core.resource.xml.ERootObject getRootObject()

getEntityResolver

public EntityResolver getEntityResolver()

fileExists

Description copied from interface: JptResourceModel

Return the model's file.

Specified by:

getFile in interface JptResourceModel

getConvertedURIFile

protected IFile getConvertedURIFile()

getFile

protected IFile getFile(URI fileURI)

Return the Eclipse file for the specified URI. This URI is assumed to be absolute in the following format:

     platform:/resource/....
