zl.lookup
Output elements of a list
Description
Outputs the elements of an input list. Element indexing begins at 0.
Arguments
initial-list[list]
optional
The object will accept a list in as an argument. A number in the right inlet will cause the object to output the element located at the list index specified by the number received in the left inlet. (if 6.2 3 5.6 5.3 3.8 2.4 is received in the right inlet, a 2 received in the left inlet will cause the object to output 5.6 out of the left output). Indexing begins at 0.
Attributes
fuzzy[atom]: 0.

zlmaxsize[atom_long]
Sets the maximum list length for all modes of operation. This is the equivalent to using an argument to the object, but allows the list length to be changed dynamically. The default list length is 256, and the maximum list length limit is 32,767.

Messages
bang
In left inlet: A bang message will output the most recent list or value calculated. Many modes of the zl object take inputs through their right inlet which will only set the input without triggering output. In these cases, a subsequent bang received in the left inlet will trigger the output.
int
In left inlet: Outputs the element located at the specified index. Indexing starts at 0.
In right inlet: Sets the list
float
See int message.
list
In left inlet: Output elements located at the specified indexes. Indexing starts at 0.
In right inlet: Set lookup list
anything
Allows for the recognition of lists that begin with symbols.
- input
[list]
mode
The word 'mode' followed by one of the following words will set the mode of the object:
change, compare, delace, ecils, group, indexmap, iter, join, lace, len, lookup, median, mth, nth, queue, reg, rev, rot, scramble, sect, slice, sort, stack, stream, sub, sum, swap, thin, union, or unique.
See the reference for the corresponding mode for more information.
