org.eclipse.core.runtime.content.XMLRootElementContentDescriber2
,
a built-in describer:
<extension point="org.eclipse.core.runtime.contentTypes"> <content-type id="ABC" base-type="org.eclipse.core.runtime.xml" file-extensions="a,b,c"> <describer class="org.eclipse.core.runtime.content.XMLRootElementContentDescriber2"> <parameter name="element" value="abc"/> </describer> </content-type> </extension>Here is an example of a simple text-based content type that has a specific file extension:
<extension point="org.eclipse.core.runtime.contentTypes"> <content-type id="MyText" base-type="org.eclipse.core.runtime.text" file-extensions="mytxt"/> </extension>When there is need to associate new file names/extensions to an existing content type (as opposed to defining a new content type), a plug-in can contribute a file association as seen below. This has the effect of enhancing the definition of the text content type to include files with names following the "*.mytxt" pattern.
<extension point="org.eclipse.core.runtime.contentTypes"> <file-association content-type="org.eclipse.core.runtime.text" file-extensions="mytxt"/> </extension>Here is an example of a content type that defines properties:
<extension point="org.eclipse.core.runtime.contentTypes"> <content-type id="MyContentType" file-extensions="dat"> <property name="file-format" value="1"/> </content-type> </extension>
The org.eclipse.core.runtime plug-in provides the following content types:
Also, the org.eclipse.core.runtime plug-in provides ready-to-use implementations of content describers:
