Example 18 with DoubleStream

use of java.util.stream.DoubleStream in project sis by apache.

the class DoubleStreamWrapper method delegate.

/**
 * Same as {@link #source()} but marks this stream is inactive.
 * All subsequent operations must be done on the returned stream.
 * This is used for {@code map(…)} and {@code flatMap(…)} operations.
 *
 * @return the stream containing actual data.
 * @throws IllegalStateException if this stream is no longer the active stream on which to apply operations.
