semantique.CollectionProxy

class semantique.CollectionProxy(obj)

Proxy object of an array collection.

This proxy object serves as a placeholder for a collection of multiple multi-dimensional arrays. All collection specific actions (i.e. verbs) can be called as methods of this object. However, the proxy object iself does not contain any data, and the actions are not applied. Instead, a textual recipe is constructed which will be executed only at the stage of query processing.

Parameters:

obj (dict) – Textual reference that can be solved by the query processor. Normally not constructed by hand, but obtained by calling one of the dedicated reference functions or by applying verbs to existing ArrayProxy or CollectionProxy instances.
