# Biber::UCollate(3pm)

Biber::UCollate objects

## NAME

Biber::UCollate - Biber::UCollate objects

### new

```
  Instantiate new Unicode::Collate::Locale object with some extra reporting checks.
  We need this also so that we can chain some things during sorting object construction.
  Without an object, we would need to call a regular subroutine but due to the special
  semantics of Schwartzian transforms, we need to chain all sorting elements so that they return
  a boolean value (see Biber.pm). This is much tidier with Foo->new()->change()->cmp than
  with something messy like "my $uc = create_uc_object; $uc->change()->cmp()" etc.
```
