Check if a timed metadata represents an ad placement opportunity

You need to check if a timed metadata represents an ad placement opportunity.

@param timedMetadata is the timed metadata to be checked
@return true if the timed metadata is an ad placement
@return false if the timed metadata is not an ad placement

Add the following code:

private boolean isPlacementOpportunity(TimedMetadata timedMetadata) {
	Metadata metadata = timedMetadata.getMetadata();
	return timedMetadata.getName().equals(OPPORTUNITY_TAG_NAME)
		&& metadata != null
		&& metadata.containsKey(OPPORTUNITY_DURATION_KEY);
	}
}
