Detailed Description

Model class in the component selector Model-View-Adapter (mediated MVC) architecture.

The other pieces are in:

This model is populated from LIB_ALIASes; helper methods in the adapter can accept entire libraries.

Quick summary of methods used to populate this class:

  • CMP_TREE_NODE_ROOT::AddLib() - add a new, empty library to the root
  • CMP_TREE_NODE_LIB::AddAlias() - add an alias and its units from a given LIB_ALIAS*

Quick summary of methods used to drive this class:

The data in the model is meant to be accessed directly. Quick summary of data members:

  • Parent - parent node, or nullptr if root
  • Children - vector of unique_ptrs to children
  • Type - ROOT, LIB, ALIAS, or UNIT
  • IntrinsicRank - cached initial sort order
  • Score - score taking into account search terms. Zero means irrelevant and should be hidden.
  • Name - name of the library/alias/unit, to be displayed
  • Desc - description of the alias, to be displayed
  • MatchName - Name, normalized to lowercase for matching
  • SearchText - normalized composite of keywords and description
  • LibId - the LIB_ID this alias or unit is from, or not valid
  • Unit - the unit number, or zero for non-units

This is a fairly expensive sort (involving string compares) so it helps to store the result of that sort.
