The IBM Remote Systems Explorer Framework feature defines plug-in for the Eclipse project which provides a generic framework for accessing remote operating system artifacts such as file system objects, message queues, processes jobs and commands programs. This feature incorporates the concept of filtering remote information. End users can define a filter which is sent to the remote system and evaluated. The result is sent back to the Remote Systems Explorer end user and displayed in the graphical user interface. An eServer iSeries extension to the Remote Systems Explorer Framework feature allows filtering of both iSeries native file system objects and Integrated File System (IFS) objects. Filtering of remote file system objects is just a specific case of the more generic problem of displaying a subset of the information in a large model by applying some sort of filtering criteria over the model. This is often required when the model is so large that it cannot easily be viewed all at once. When modelling real world information in computer software, some internal representation needs to be used in order to preserve relationships in the information. A tree structure is frequently used to store the representation of a file system due to its hierarchical nature. In the case of the eServer iSeries extension to the Remote Systems Explorer Framework the entire model (a representation of the remote file system) is never loaded entirely into memory for the following reasons: The end user will typically only work with a small subset of the entire file system
