Release 10.1A: OpenEdge Development:
Java Open Clients

> ## ProChangeSummary class

> OpenEdge provides a Java class, `com.progress.open4gl.ProChangeSummary`, that tracks changes to a `ProDataGraph`. The `ProChangeSummary` class extends the Java SDO `ChangeSummary` class, which is contained within a `DataGraph`. It records changes to any of the underlying `DataObject` instances in a `DataGraph`, including modifications, deletions, and additions of `DataObject` instances from given starting state. At a later point in the update cycle of a `ProDataGraph`, when you invoke the `ProDataGraph.acceptChanges()` method, the contained `ProChangeSummary` object resets to begin tracking changes from a new starting state of the `ProDataGraph`.

> The `com.progress.open4gl.ProChangeSummary` class provides no constructor, because it is internally managed entirely by the `ProDataGraph` that contains it. It does provide the following inherited and extended methods.
