Questions

• Can the same dimension (type) be used as a row and column dimension at the same time?

Key Concepts

• A dimension is always passed around as its JSON representation.
• No two-way bindings on the settings data object itself!
• Dimension components only used to work with settings, nothing else.
• Composer only used to maintain lists of Dimension settings objects, nothing else.
• A Dimension can be valid or invalid.
• Only valid Dimensions are send to the application
• => only valid Dimensions are stored in/known to the Composer

Rules

• No function longer than 10 lines! Anywhere.

reporting-dimension

Actions Interface

• update send after valid settings change, passes this (?)
• delete send when dimension should be deleted, passes this

Actions

• edit toggles isEditing
• delete delegates to sendAction

Properties

• type type of dimension, override in subclass

• caption summary of current setting, override in subclass

• isValid boolean flag, result of validation

• isEditing boolean flag, state of editing

• settings object to hold all define-able dimension settings

Methods

• validate checks that all settings are valid, sets & returns isValid
• toJSON returns a consumable representation of this dimension in JSON

carries-dimension extends reporting-dimension (Example)

Properties

• type override, set to 'Carriers'
• caption override, set to CP based on settings to show summary

Methods

• validate override, check carriers-specific settings
• toJSON override, compose carriers-specific JSON representation

table-composer

Actions Interface

• save send when the current state of the composer should be saved
• update send when rows or cols changed, i.e. after add, update, delete

Actions

• add(where, type) (rows|cols), (dimension type). pushes a new dimension object
• update(dim) the dim settings object. updates its own copy in rows/cols with dim
• delete(dim) the dim settings object. removes dim from its rows/cols
• save gathers and concats all its rows/cols data, �delegates to sendAction

Properties

• rows array, all row dimension objects
• cols array, all column dimension objects
• dimensions array, all defined dimensions

Methods

• toJSON returns a nice representation of its current rows and cols
