Storage Mergers

Identifier:
org.eclipse.team.core.storageMergers

Since:
3.2

Description:
This extension point allows a plug-in to register a storage merger for specific content types. The storage merger is expected to perform a three-way merge on three input storage and write the result to an output stream. The extension point must implement the interface org.eclipse.team.core.mapping.IStorageMerger.

Configuration Markup:

<!ELEMENT extension ( storageMerger* , contentTypeBinding*)>

<!ATTLIST extension

point CDATA #REQUIRED

id    CDATA #IMPLIED

name  CDATA #IMPLIED

>

  • point - a fully qualified identifier of the target extension point
  • id - an optional identifier of the extension instance
  • name - an optional name of the extension instance

<!ELEMENT storageMerger EMPTY>

<!ATTLIST storageMerger

id         CDATA #REQUIRED

class      CDATA #REQUIRED

extensions CDATA #IMPLIED

>

  • id - a unique identifier that can be used to reference the storage merger
  • class - a fully qualified name of a class that implements org.eclipse.team.core.mapping.IStorageMerger
  • extensions - a comma separated list of file extensions e.g. "java, properties"

<!ELEMENT contentTypeBinding EMPTY>

<!ATTLIST contentTypeBinding

contentTypeId   IDREF #REQUIRED

storageMergerId IDREF #REQUIRED

>

  • contentTypeId - The id of a content type defined using the org.eclipse.core.contenttype.contentTypes extension point.
  • storageMergerId -

Examples:
The following is an example of a storage merger for property files (extension "properties"):


<extension point = 
"org.eclipse.team.core.storageMergers"
> 
     <storageMerger 
         id=
"org.eclipse.team.internal.core.merge.PropertiesStorageMerger"
 
         class=
"org.eclipse.team.internal.core.merge.PropertiesStorageMerger"
 
         extensions=
"properties"
 
    /> 
</extension> 

Supplied Implementation:
The Team UI plugin defines a storage merger for line oriented text files.
