-<b>WARNING: This extension point is DEPRECATED.</b><br>
-Do not use this extension point, it will be removed in future versions of this product.
-Instead, use the extension point <a href="org_eclipse_core_contenttype_contentTypes.html">org.eclipse.core.contenttype.contentTypes</a>
-</p>
-The content types extension point allows plug-ins to contribute to the platform content type catalog. There are two forms of contributions: <cite>content types</cite> and <cite>file associations</cite>.
-<ul>
-<li>
-a content type represents a file format and its naming conventions. Content types can be defined from scratch, or can inherit from existing ones, specializing them. Also, a content type can be made into an alias for another content type (see the <code>alias-for</code> attribute). When this feature is used:
- <ul><li>if the target is absent, the alias content type is processed
- as a normal content type;</li>
- <li>if the target is present, all references to the alias type are automatically
- transformed into references to the target type, and the alias type cannot be
- accessed nor is exposed through the API.</li></ul>
-</li>
-<li>
-a file association extends an existing content type by associating new file names and/or extensions to it</li>
-</ul>

-
-
- the default charset for this content type, or an empty string, if this content type should not have a default charset even if the parent has one. This is a convenience attribute, equivalent to specifying:

- <property name="org.eclipse.core.runtime.charset" default="charset-name"/>
- </content-type>
-</pre>
-
-

- the fully qualified identifier of the content type this content type is an alias for

-
- the fully qualified name of a class that implements <samp>org.eclipse.core.runtime.content.IContentDescriber</samp> or <samp>org.eclipse.core.runtime.content.ITextContentDescriber</samp>, or an empty string, if this content type should not have a describer even if the parent has one

-
- the name of this parameter made available to instances of the specified content describer class

-
-
-
-
- an arbitrary value associated with the given name and made available to instances of the specified content describer class
-
-
-
-
-
-
-
-
-
- Declares a property related to this content type, optionally assigning a default value. See <samp>org.eclipse.core.runtime.content.IContentDescription</samp> for more information on properties.
-
-
-
-
-
-
- the name of the property. If the property is being overridden and has been originally defined in a different namespace, a fully qualified property name must be used
-
-
-
-
-

- Following is an example of an XML-based content type declaration using <code>org.eclipse.core.runtime.content.XMLRootElementContentDescriber2</code>,
-a built-in describer:
-<p>
-<pre>
- <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>
-</pre>
-</p>
-Here is an example of a simple text-based content type that has a specific file extension:
-<p>
-<pre>
- <extension point="org.eclipse.core.runtime.contentTypes">
- <content-type id="MyText"
- base-type="org.eclipse.core.runtime.text"
- file-extensions="mytxt"/>
- </extension>
-</pre>
-</p>
-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.
-<p>
-<pre>
- <extension point="org.eclipse.core.runtime.contentTypes">
- <file-association
- content-type="org.eclipse.core.runtime.text"
- file-extensions="mytxt"/>
- </extension>
-</pre>
-</p>
-Here is an example of a content type that defines properties:
-<pre>
- <extension point="org.eclipse.core.runtime.contentTypes">
- <content-type id="MyContentType"
- file-extensions="dat">
- <property name="file-format" value="1"/>
- </content-type>
- </extension>
-</pre>
-</p>
-
-
-
-
-
-
-
-
- The value of the class attribute in the describer element must represent an
-implementor of
-<samp>org.eclipse.core.runtime.content.IContentDescriber</samp> or <samp>org.eclipse.core.runtime.content.ITextContentDescriber</samp>.
-
-<samp>org.eclipse.core.runtime.content.IContentDescription</samp> objects returned by the <samp>org.eclipse.core.runtime.content</samp> API
-
-
-
-
-
-
-
-
- <p>The org.eclipse.core.runtime plug-in provides the following content types:<ul>
-<li>org.eclipse.core.runtime.text</li>
-<li>org.eclipse.core.runtime.xml</li>
-</ul>
-Other plug-ins in the platform contribute other content types.
-</p>
-<p>
-Also, the org.eclipse.core.runtime plug-in provides ready-to-use implementations of content describers:<ul>
-<li>org.eclipse.core.runtime.content.XMLRootElementContentDescriber2</li>
-<li>org.eclipse.core.runtime.content.BinarySignatureDescriber</li>
-</ul>
-</p>
