Structure Creators

Identifier:
org.eclipse.compare.structureCreators

Description:
This extension point allows a plug-in to register a structure creator for specific content types. The structure creator is expected to create a tree of IStructureComparators for a given content. This tree is used as the input for the structural compare. The extension point must implement the interface org.eclipse.compare.structuremergeviewer.IStructureCreator.

Configuration Markup:

<!ELEMENT extension ( structureCreator* , 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 structureCreator EMPTY>

<!ATTLIST structureCreator

id         CDATA #REQUIRED

class      CDATA #REQUIRED

extensions CDATA #IMPLIED

>

  • id - a unique identifier that can be used to reference the structure creator
  • class - a fully qualified name of a class that implements org.eclipse.compare.structuremergeviewer.IStructureCreator
  • extensions - a comma separated list of file extensions e.g. "java, properties"

<!ELEMENT contentTypeBinding EMPTY>

<!ATTLIST contentTypeBinding

contentTypeId      IDREF #REQUIRED

structureCreatorId IDREF #REQUIRED

>

A contentTypeBinding binds a structure creator to a content type.


  • contentTypeId - The id of a content type defined using the org.eclipse.core.contenttype.contentTypes extension point.
  • structureCreatorId - The id of a structure creator defined using the structureCreator element of this extension point (i.e. org.eclipse.compare.structureCreators)

Examples:
The following is an example of a structure creator for java files (extension "java"):


<extension point = 
"org.eclipse.compare.structureCreators"
> 
     <structureCreator 
         id=
"org.eclipse.compare.JavaStructureCreator"
 
         class=
"org.eclipse.compare.JavaStructureCreator"
 
         extensions=
"java"
 
    /> 
</extension> 

Supplied Implementation:
The Compare UI plugin defines a structure creator for zip archives.
