List of newStream() Examples

Examples of newStream()

cl.niclabs.skandium.Skandium.newStream()
Factory method is used to create a new {@link Stream}, which in turn can be used to input parameters for computation. @param < P> The type of skeleton program's input. @param < R> The type of the skeleton programs' result. @param skeleton The skeleton program which will be used to compute each parameter entered through the {@link Stream}. @return A new {@link Stream} associated with the specified {@link cl.niclabs.skandium.skeletons.Skeleton} program.
javax.mail.internet.SharedInputStream.newStream()
javax.mail.util.SharedFileInputStream.newStream()
Return a new InputStream representing a subset of the data from this InputStream, starting at start (inclusive) up to end (exclusive). start must be non-negative. If end is -1, the new stream ends at the same place as this stream. The returned InputStream will also implement the SharedInputStream interface. @param start the starting position @param end the ending position + 1 @return the new stream
