constructor (SAP Library - SAP Tree and Tree Model (BC-CI))

constructor

The constructor method is called automatically when you instantiate the class cl_column_tree_model . To do this, you must declare a reference variable as follows:

DATA column_model TYPE REF TO cl_column_tree_model.

You can then create an instance using the CREATE OBJECT statement.

CREATE OBJECT column_model
      EXPORTING node_selection_mode = node_selection_mode
                hide_selection      = hide_selection
                item_selection      = item_selection
                hierarchy_column_name = hierarchy_colunm_name
                hierarchy_header    = hierarchy_header.
