Method Details

isEnabled

default boolean isEnabled()

Returns true if the counter is enabled.

This allows callers to avoid unnecessary compute when nothing is consuming the data. Because the response is subject to change over the application, callers should call this before each call to add(double), add(double, Attributes), or add(double, Attributes, Context).
