Merging multiple files
In some cases, the ability to merge files without the assist of a user
is desirable. The extension point
org.eclipse.team.core.storageMergers
allows you to contribute a class that merges three different files (or storage units) into a single output stream. Storage mergers
can be associated with file extensions or bound to a particular content type. The Platform defines a storage
merger for merging three files of plain text:
<extension
point="org.eclipse.team.core.storageMergers">
<storageMerger
extensions="txt"
class="org.eclipse.team.internal.ui.mapping.TextStorageMerger"
id="org.eclipse.team.ui.textStorageMerger">
</storageMerger>
<contentTypeBinding
contentTypeId="org.eclipse.core.runtime.text"
streamMergerId="org.eclipse.team.ui.textStorageMerger">
</contentTypeBinding>
</extension>
The storage merger itself is described in the storageMerger element. You must specify the id of the
merger and the class that implements it. You may also specify any file extensions for which the
the storage merger should be used.
You may also use the contentTypeBinding element to associate a
content type
with a storage merger.
Storage mergers must implement
IStorageMerger.
This simple interface merges the contents from three different storage units into a single output stream.
The not-so-simple implementation depends upon your plug-in and its content types.
