MENull layout (MEOop receiver, METype layoutRelationship, METype fromRole,
METype toRole, string direction, boolean manhattan)
Creates a new diagram representation with automatic layout for
the graph denoted by the first MEOop argument. The auto-layout algorithm assumes
a directed acyclic graph (DAG) as its input and therefore the user must provide
the API call with rules according to which the DAG is built. Therefore, the
following argument, relationship, defines the relationship type which instances
appear as edges in the DAG. The two following arguments, parentRole and
childRole, define the directivity according to which the DAG is build. The fifth
argument, direction, provides the information how the layout is distributed and
can have either 'vertical' or 'horizontal' as values. The final argument,
manhattan, toggles the usage of orthogonal or diagonal lines between DAG nodes.
If the layout algorithm encounters cycle in the graph, it will proceed
automatically with a loose tree (as if the cycle had been broken).

|
MEOop addNewObjectRepFor (MEOop receiver, MEOop
addNewObjectRepFor, int beforeIndex, MEAny place)
Adds a new object representation to the receiver argument, a
diagram MEOop. The second argument is the MEOop of the object to represent. The
third argument is a 1-based integer before which to insert the new binding
representation in the Z-ordered collection of binding representations, 1 being
the backmost element (use 0 to place the object at the top of the Z-order). The
fourth argument is an MEAny containing the point position of the new object
representation. The return value is the MEOop of the new object
representation.
|
|
MEOop addNewBindingRepFor (MEOop receiver, MEOop addNewBindingRepFor, int
beforeIndex, MEAny place)
Adds a new binding representation to the receiver argument, a
diagram MEOop. The second argument is the MEOop of the binding to represent. The
third argument is a 1-based integer before which to insert the new binding
representation in the Z-ordered collection of binding representations, 1 being
the backmost element (use 0 to place the object at the top of the Z-order). The
fourth argument is an MEAny containg the point position of the relationship
representation. The return value is the MEOop of the new binding
representation.

id of the connection within this binding.
|
|
boolean isMovable (MEOop receiver, int isMovableWithId)
Returns a boolean indicating whether the target point offset
of a given binding connection should be interpreted as the offset for the whole
dynamic port (if connected to one) or just as the offset for the role's

MEOop. The second argument is the integer id of the connection within this
binding.
|
|
MENull setIsMovable (MEOop receiver, boolean isMovable, int id)
Sets the boolean indicating whether the target point offset of
a given binding connection should be interpreted as the offset for the whole
dynamic port (if connected to one) or just as the offset for the role's

whole dynamic port. The third argument is the integer id of the connection
within this binding.
