Class Method Details

.segment(segment_name) ⇒ Object

Creates a new segment which behaves almost the same as a Document class dynamically configured to access a segmented index.

It creates a new class in runtime that inherits from your defined class, allowing methods defined in your class to be callable from the dynamic class.
