zl.lookup Reference

Output elements of a list

zl.lookup

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

zlmaxsize [atom_long]

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

Arguments

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.
