Class JControlModel.MatchRule

java.lang.Object
  org.eclipse.emf.codegen.merge.java.JControlModel.MatchRule

Enclosing class:

JControlModel

public static class JControlModel.MatchRule
extends java.lang.Object

During the merge, the current state of the nodes of a tree is applied to the nodes of another tree. Pairing the nodes of each tree is one of the main activities of the process.

A Match Rule allows a developer to replace the default matching algorithm, based on qualified names, to better suite the needs of an specific application. Some examples:

   <merge:match markup="^gen$" get="Member/getName"/>
   <merge:match get="Method/getComment" signature="\s*@\s*uuid\s*(\S*)\s*\n"/>

The first match rule is applicable to any Member marked with the expression defined by the "^gen$" Dictionary Pattern. It defines that these members are matched by their names. The second rule is applicable to any method that has @uuid xyz on its comment. In this case, the string xyz is be used to match the nodes.

An important remark is that if there is a type conversion during the merge process, the match rules should not be used to pair different "kinds" of elements like fields and enumerator constants for example. See Jmerger.convert and NodeConverter for further details on conversions.
