getConfigProperty

public final Object getConfigProperty(String namespace,
                                      Object o,
                                      Map defaultProperties,
                                      Object keyDeriver,
                                      String key)

Derive property config for modelId (if defined) else default from admin.properties
Class name . modelId ; for any custom config(s). Within the SpringStaticConfiguration, the value is a Map of key, values of the key matching whats in the admin config for default categories

Parameters:

namespace - as String

o - as Object for while overrides are being seeked. The Object is typically some UI component model.
o can also be a List; if its a List then it will search for configuration from left (first) to right (last). This is useful is scanning a hierarchy for properties, where a parent is to the right in sequence in the list.

keyDeriver - as String or Transformer which can be null, for the model this Panel instance represents for which we expect config overrides. It acts on the object (o).

defaultProperties - as Map (nullable)

key - as String, as the key property we wish to fetch

Returns:

Object

Note: With o or keyDeriver null; this method simply gets the key from the param defaultProperties.

The following code summarizes the essence:

                Map configValueAsMap = springStaticConfigSource.get(
                                namespace, 
                                (String)(keyDeriver instanceof Transformer?((Transformer)keyDeriver).transform(o):keyDeriver)
                );              
                if (configValueAsMap!=null) {
                        value = (String)configValueAsMap.get(key);
                }
 

TODO: All admin code should use this instead of a direct property access

getConfigProperty

public final <V> V getConfigProperty(String key,
                                     Map defaultProperties,
                                     V defaultValue)

A simple alternative that checks defaultProperties and if none found then applies a given default value

Parameters:

key - as String

defaultProperties - as Map of key to output type V

defaultValue - as output type V

Returns:

type V
