Overview

Base class for bit operations (AND, OR, XOR). Please note that each bit operation creates a new key prefixed with ‘bitanalytics_bitop_`. These temporary keys can be deleted with `delete_temporary_bitop_keys`. You can even nest bit operations.

Example

active_2_months = @bit_analytics.bit_op_and(
    @bit_analytics.month_events('active', last_month.year, last_month.month),
    @bit_analytics.month_events('active', now.year, now.month)
)
active_2_months = @bit_analytics.bit_op_and(
    @bit_analytics.bit_op_and(
        @bit_analytics.month_events('active', last_month.year, last_month.month),
        @bit_analytics.month_events('active', now.year, now.month)
    ),
    @bit_analytics.month_events('active', now.year, now.month)
)
