Introduction

Content can represent the state of a topic.

It may also form the body of a message sent to or from a client. A content object is immutable.

Note: The use of this interface is being phased out in favor of specific data types. The only remaining places where it must be used is in implementations conforming to the older messaging delegate protocols PTDiffusionMessageDelegate and PTDiffusionMessageStreamDelegate, and in implementations conforming to the fetch delegate protocol PTDiffusionFetchStreamDelegate. In all other cases its use should be avoided.

- (BOOL) isEqualToContent: (nullable PTDiffusionContent *) content

Compares the receiver to the given content.

Parameters

content The content object with which to compare the receiver.

Returns: YES if the data in content is equal to the contents of the receiver, otherwise NO.

Note: Two content objects are equal if they hold the same number of data bytes, and if the bytes at the same position in the objects are the same.

- (nullable PTDiffusionRecordContent *) recordContentWithSchema:	(PTDiffusionRecordContentSchema *)	schema
error:	(NSError **)	error

Returns the data interpreted as records and transformed using associated metadata drawn from the given schema.

This method will return nil if an error occurred.

Parameters

schema	A schema to be applied to the data as it's interpreted.
