Connect join objects to two or more streams, windows, or Flex operators. Join
objects can take input from two or more objects, but can produce only one
output.
Note: Streams, windows and delta streams can participate
in a join. However, a delta stream may participate in a join only if it has
a KEEP clause specified. Only one stream
can participate in a join. For details of supported joins, see the Programmers Guide.
Tip: To add multiple
connections, Shift+click and hold the Connector tool and add connections. To return to normal
selection, press Esc or click the Select tool in the Palette to release it.
