#This class is an initializer and can be used with all the objects that inherit the Component class. It allows to initialize an object from a dictionary.
|
|
#It could be a simple key/value dictionary where each variable (key) has a certain value (value) like, for instance
|
|
#\verbatim
|
|
# dictionary = {'VARIABLE1':value1,'VARIABLE2':value2}
|
|
#\endverbatim
|
|
#or more in general a dictionary of
|
|
#dictionaries where each variable (key) has several attributes like value,doc,units etc. like for instance
|
|
#\verbatim
|
|
# dictionary = {'VARIABLE1':{'value':value1,'doc':'documentation for variable1,'units':m/s},'VARIABLE2':{'value':value2,'doc':'documentation for variable2}}
|
|
#\endverbatim
|
|
#If some of the names in the adopted in the initializing dictionary differ from the names adopted in the object to be initialized,
|
|
# one could provide a translator, i.e. a dictionary where the key is to name of the variable as known in the
|
|
#initialinzing dictionary and the value is the name of the variable as known in the object to be initialized. The name of the variables are the ones
|
|
#specified in the self.dictionaryOfVariables of each object (see Component).
|
|
|
|
# Once an instance of this class is created (say obj), the object that needs to be initialized invokes the initComponent(obj) method (inherited from the Component class) passing the instance as argument.
