SHSignature

An object that contains the opaque data and other information for a signature.

Declaration

class SHSignature

Overview

You can save signatures to files and share them with others. Use saved signatures to populate a custom catalog.

Check whether your captured query signature is long enough to search for a match by comparing duration to the minimumQuerySignatureDuration and maximumQuerySignatureDuration of a catalog.

For signatures longer than maximumQuerySignatureDuration, use slices(from:duration:stride:) to create multiple segments that meet the duration requirement.
