mode :string

One of "normal", "edit", or "uiBuilder". "normal" renders a regular filter used to update a search model in a DataCatalogViewWithFilters. "edit" creates a filter that cannot update a search model, but which has an "EDIT" button that opens a modal with an interface for editing the filter model's properties (e.g. fields, model type, etc.). "uiBuilder" is the view of the filter within this editing modal; it has inputs that are overlaid above the filter elements where a user can edit the placeholder text, label, etc. in a WYSIWYG fashion.

Methods

defocus()

Helper function which defocuses the dropdown portion of the SearchableSelectView used by this View's AnnotationFilterView. When the user clicks an item in the NCBOTree widget, we want the SearchableSelectView's dropdown to go away and I couldn't find any API to do that so we have this code. See the render() method to see how it's called. Note: This isn't really a stable API and is really something we might remove in the future if we refactor the NCBOTree widget.

hideInputError(input, messageContainer)

input HTMLElement The input that had an error associated with its value
messageContainer HTMLElement The element in which the error message was inserted

render()

Render an instance of a Semantic Filter View. Note that this View doesn't have a template and instead delegates to the AnnotationFilterView which renders a SearchableSelectView which renders an NCBOTree.
Since:
  • 2.22.0
Overrides:
Source:

setLabelMapping(term, label)

Set the human-readable label for a term URI. For most uses of the Filter model, the value(s) set on the model can be shown directly in the UI. But for Semantic searches, we need to be able to display a human-readable label for the value because the value is likely an opaque URI. Rather than fetch and/or store all the possible labels for all possible URIs, we store a label for whichever terms the user chooses and keep that around until we need it in the UI.
Parameters:
Name Type Description
term string The term URI to set a label for
label string The label to set

message string The error message to show
