parameters object, or a Component
if no parameters required.

Properties
Name Type Attributes Default Description
componentSource baja.Component | module:nmodule/webEditors/rc/wb/table/model/ComponentSource

the source of components to build into table rows.
If a Component is given it will just be wrapped in a ComponentSource

setRowFilter(rowFilterFunction) → {Promise}

Description:

  • Filter the table's rows according to the given filter function. Setting
    the rowFilterFunction to null will remove the current filter and
    reset the table model to display all rows.

    Will trigger a rowsFiltered tinyevent.

    Remember that Array#filter is synchronous, so if the filter needs to use
    any data that is asynchronously retrieved, the async work must be performed
    before the filter so that the filter function can work synchronously.

Source:
Inherited From:
Parameters:
Name Type Description
rowFilterFunction function

standard array filter function
Throws:

if a non-Function is given

Type
Error
Returns:

to be resolved after any necessary post-filtering work (this does not make
the filtering itself asynchronous).

Type
Promise

sort(sortFunction) → {Promise}

Description:

  • Sort the table's rows according to the given sort function. Emits a
    rowsReordered event.

    Remember that Array#sort is synchronous, so if the sort needs to use
    any data that is asynchronously retrieved, the async work must be performed
    before the sort so that the sort function can work synchronously.

Source:
Inherited From:
Parameters:
Name Type Description
sortFunction function

standard array sort function to receive
two Row instances
Throws:

if a non-Function is given

Type
Error
Returns:

to be resolved after any necessary post-sorting work (this does not make
the sorting itself asynchronous).

Type
Promise

(inner) exec(updates) → {Promise}

Description:

  • This throttles the addition / removal of rows in the table.

Source:
Parameters:
