Invoked by right clicking on a relation class in the legend tab box. Not shown as an option for the current containmentship relation. When creating relations initially assign them to this indicated class.

Forms hierarchy

Invoked by right clicking on a relation class in the legend tab box. This action brings up a dialog permitting further relation classes to be named as subordinate ones that are to contribute to the process of forming a spanning tree of the Landscape graph. Set the relation classes used to implement a containment hierarchy.

The containment hierarchy is formed as a spanning tree over the landscape graph, where spanning tree edges are constrained to be relations in the graph of the specified relation classes. Relations associated with earlier named relation classes will always be chosen as the preferred spanning edges forming part of the spanning tree

The constructed spanning tree that determines containment will be constructed even if the relations of the specified relation classes do not form a tree. Warnings will be given in the results tab of relations not included in the spanning tree because either (a) they formed a cycle or (b) they were redundant; the destination node reached from them already having been placed in the spanning tree by some earlier considered relation of the correct class.

Spanning relation classes in order of priority will be shown in the legend and query box, except when they are not the primary spanning relation class, and do not contribute to the construction of the actual spanning tree formed.

When multiple relation class contribute to forming a containment heirarchy the tool tip message associated with an entity will include the name of the class of the spanning relation that resulted in it being contained within its parent container.

Create Entity Class

Invoked by right clicking on a blank region of the legend tab box. Create a new entity class.

This operation resets the IO points in all active entities under the draw root that are associated with active relation classes.

AA Cluster (P)

The AA clusterer clusters entities on user specified patterns.

ACDC Cluster (shift P)

The ACDC clusterer clusters entities on specific attributes contained within them.

Bunch Cluster (shift R)

The bunch clusterer (documentation available here) contains within itself a wide variety of methods by which entities may be clustered. Note that use of this option requires access to the java wrapper named "clue", and to the bunch.jar files.

Cluster using program (I)

This option permits an arbitrary external program to be presented with TA that conveys the entities to be clustered, and to emit TA that subsequently tells LSEdit how to cluster these entities. However the lack of any ability to easily configure such a clusterer within lsedit suggests that should additional clusterers be used within LSEdit, then LSEdit should be extended to understand the capabilities of these clusterers, so that it can permit information about them to be configured through dialogs rather than through a command line interface.

Redistribute (shift W)

This option redistributes selected entities or entities connected by selected relations, so as to maximise the internal connectivity of the resulting clusters. It is a useful operation that may be performed subsequent to any clustering operation, to refine the resulting clusters.

Group unconnected (W)

Marks those entities as selected which have no edges into or out of them, so that these entities can subsequently be manipulated as a group.

Cluster metrics (Q)

Generates various clustering metrics. These may be remembered and compared to later computed metrics.

Reconfigure layouters (alt J)

This option permits all of the layout and clustering algorithms to be configured. Configuration information is remembered between invocations of LSEdit. This option also permits the default layout algorithm to be applied to diagrams lacking layout information to be changed.

Sync TOC with diagram (alt P)

Invoked either from the main menu or by right clicking on the TOC tab box. Syncing the TOC with the diagram causes precisely those entities on the path back to the root node within the graph containment hierarchy to be opened, thus providing a visual indication of the path through this containment hierarchy to the currently visible items within the diagram.

This structure can itself consume considerable memory, and since it must be kept in sync with the diagram involves updating as the diagram changes. If desired this structure can be discarded by merely electing to hide the contents of this tab box. Having hidden the contents of this tab box, updates become slightly more efficient, and considerable memory may be recovered. The contents of this tab box can later be reconstructed on demand.

Reset I/O points

The position at which relations of a given class connect to entities can be determined either by lsedit directly; by specifying a class_iofactor attribute in the range 0.0 to 1.0 associated with the relation class; or for each of the four sides of an entity individually tailored by moving the cursor over the connection point until the cursor changes to a + and then dragging the connection point to an arbitrary location on the edge of the entity. To clear any manual settings for a given relation class right click on that relation class in the legend box and select this action. To clear all manual settings, right click on the legend box itself and select this action.
