Call (SwimOS)

All Superinterfaces:

Cont<T>
```
public interface Call<T>
extends Cont<T>
```
Handle used to eventually complete an asynchronous operation by invoking a Continuation. A Call abstracts over the execution context in which a Continuation runs. Think of a Call as a way to asynchronously invoke Cont.bind(T), and Cont#trap(Throwable). Use Stage.call(Cont) to get a Call that asynchronously executes a Continuation on an execution Stage.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`bind(T value)`	Completes this `Call` with a `value` by eventually invoking the `bind(T)` method of this `Call`'s `Cont`inuation.
`Cont<T>`	`cont()`	Returns the `Cont`inuation that this `Call` completes.
`void`	`trap(Throwable error)`	Completes this `Call` with an `error` by eventually invoking the `trap(Throwable)` method of this `Call`'s `Cont`inuation.
`boolean`	`tryBind(T value)`	Tries to complete this `Call` with a `value`, returning `true` if this operation caused the completion of the `Call`; returns `false` if this `Call` was already completed.
`boolean`	`tryTrap(Throwable error)`	Tries to complete this `Call` with an `error`, returning `true` if this operation caused the completion of the `Call`; returns `false` if this `Call` was already completed.

- Method Detail
  - cont
```
Cont<T> cont()
```
    Returns the Continuation that this Call completes.
  - bind
```
void bind(T value)
```
    Completes this Call with a value by eventually invoking the bind(T) method of this Call's Continuation.
    
    Specified by:
    
    bind in interface Cont<T>
    
    Throws:
    
    ContException - if this Call has already been completed.
  - trap
```
void trap(Throwable error)
```
    Completes this Call with an error by eventually invoking the trap(Throwable) method of this Call's Continuation.
    
    Specified by:
    
    trap in interface Cont<T>
    
    Throws:
    
    ContException - if this Call has already been completed.
  - tryBind
```
boolean tryBind(T value)
```
    Tries to complete this Call with a value, returning true if this operation caused the completion of the Call; returns false if this Call was already completed. If successful, the bind(T) method of this Call's Continuation will eventually be invoked.
  - tryTrap
```
boolean tryTrap(Throwable error)
```
    Tries to complete this Call with an error, returning true if this operation caused the completion of the Call; returns false if this Call was already completed. If successful, the trap(Throwable) method of this Call's Continuation will eventually be invoked.
