extension (clients: Vector[Client])
def matching(expr: Expr[JavaClient]): Vector[Client]

extension (panes: Vector[Pane])
def matching(expr: Expr[JavaPane]): Vector[Pane]

extension (sessions: Vector[Session])

```

The captured clients `expr` matches: a local filter over what is already held.

## Parameters

- `expr` (`Expr[JavaClient]`) (for `matching(expr) [overload 1]`)
- `expr` (`Expr[JavaPane]`) (for `matching(expr) [overload 2]`)
- `expr` (`Expr[JavaSession]`) (for `matching(expr) [overload 3]`)
- `expr` (`Expr[JavaWindow]`) (for `matching(expr) [overload 4]`)
