Inherits from RedlandWrappedObject : NSObject

Overview

A RedlandStream represents a stream of statements.

Streams are used as return values from parsers and query functions in the Redland library. It is recommended that you use the statementEnumerator function to access the stream, as it provides a more natural Cocoa interface using an NSEnumerator subclass.

Tasks

  • – wrappedStream

    Returns the underlying librdf_stream pointer of the receiver.
  • – next
    • Returns YES if there is a next statement. Note that the return value is the inverse of the corresponding C library function, which returns zero on success.
  • – object

    Returns the current object on the stream.
  • – context

    Returns the context of the current object on the stream.
  • – statementEnumerator
    • Returns a RedlandStreamEnumerator for the receiver. It is recommended that you use this enumerator interface instead of accessing the stream directly.

Instance Methods
