Class CFSheet

A ProjectionSheet providing access to the ConnectionFields in its CFProjections.

CFSheet is a Sheet built from units indexed by Sheet coordinates (x,y). Each unit can have one or more ConnectionFields on another Sheet (via this sheet's CFProjections). Thus CFSheet is a more concrete version of a ProjectionSheet; a ProjectionSheet does not require that there be units or weights of any kind. Unless you need access to the underlying ConnectionFields for visualization or analysis, CFSheet and ProjectionSheet are interchangeable.

measure_maps = param.Boolean(True, doc= ...
Whether to include this Sheet when measuring various maps to create SheetViews.

Method Details

update_unit_view(self, x, y, proj_name=`''`)

Creates the list of UnitView objects for a particular unit in this CFSheet. (There is one UnitView for each Projection to this CFSheet).

Each UnitView is then added to the sheet_views of its source sheet. It returns the list of all UnitViews for the given unit.

Class Variable Details

measure_maps

Whether to include this Sheet when measuring various maps to create SheetViews.

Value:

param.Boolean(True, doc= """
        Whether to include this Sheet when measuring various maps to create SheetV
iews.""")

precedence

Allows a sorting order for Sheets, e.g. in the GUI.

Value:

param.Number(0.5)
