offer Reference

Store one-time number pairs

offer

Description

Store two ints as an x, y pair, and access them by x value. When a pair is retrieved, it is deleted from the collection.

Examples

A pair of numbers can be stored, then recalled a single time

Discussion

offer was designed for use with algorithms that transform the pitch of an incoming note stream. By storing the original and transformed note together (the transformed may be sent in the right inlet, immediately followed by the original, or they can be sent as a list) when the pitch of the note-on is changed, the transformed pitch can be retrieved when the note-off is received.

Arguments

None.

Messages

bang

bang will cause offer to output every y-value received since the last clear message was received (or since the last initialization).

int

Arguments

x [int]
In left inlet: The number specifies the x value of an x,y pair. If a y value has been received in the right inlet, the two numbers are stored together in offer; otherwise, offer looks for an x value that matches the incoming number, sends out the corresponding y value, then deletes the stored pair. If there is no x value stored in offer that matches the number received, offer does nothing.

  (inlet1)

Arguments

y-value [int]
In right inlet: The number specifies a y value to be stored in offer. The next x value (int) received in the left inlet causes the two numbers to be stored together as an x,y pair.

clear

In left inlet: Deletes the entire contents of offer.

Output

int

If the number received in the left inlet matches the x value of an x,y pair stored in offer, the corresponding y value is sent out and the stored pair is deleted.
