array.stream

Make an array of a certain size

Description

array.stream accepts a number in the right inlet which specifies the length of the output array. Following the receipt of this number, the object will collect this number of elements input through the left inlet. After the array-length is complete, and with each subsequent input, the array will be output from the left outlet. A 1 or a 0 will be output from the right outlet depending on whether the array-length has been reached or not. A 1 signifies that the array-length has been reached and that the object is now collecting the stream. Use the clear message to reset the array.

Arguments

None.
