Call

All Implemented Interfaces:

kotlin.Cloneable
```
public interface Call<T extends Object>
 implements Cloneable
                    
```
An invocation of an SDK call that sends a request to Square servers and returns a response. Each call yields its own request and response. Use clone to make multiple calls with the same parameters to the same web server; this may be used to retry a failed call.
Calls may be executed synchronously with execute, or asynchronously with enqueue. In either case the call can be canceled at any time with cancel.

Method Summary

Modifier and Type	Method	Description
`abstract T`	`execute()`	Synchronously sends the request and returns the result.
`abstract Unit`	`enqueue(Callback<T> callback)`	Asynchronously sends the request and notifies callback of the result.
`abstract Boolean`	`isExecuted()`	True if this call has been either executed or enqueued.
`abstract Unit`	`cancel()`	Cancels this call.
`abstract Boolean`	`isCanceled()`	True if cancel was called.
`abstract Call<T>`	`clone()`	Creates a new, identical call to this one which can be enqueued or executed even if this call has already been executed.

- Method Detail
  - execute
```
 abstract T execute()
```
    Synchronously sends the request and returns the result.
  - enqueue
```
 abstract Unit enqueue(Callback<T> callback)
```
    Asynchronously sends the request and notifies callback of the result.
  - isExecuted
```
 abstract Boolean isExecuted()
```
    True if this call has been either executed or enqueued. It is an error to execute or enqueue a call more than once.
  - cancel
```
 abstract Unit cancel()
```
    Cancels this call. An attempt will be made to cancel in-flight calls, and if the call has not yet been executed it never will be.
  - isCanceled
```
 abstract Boolean isCanceled()
```
    True if cancel was called.
  - clone
```
 abstract Call<T> clone()
```
    Creates a new, identical call to this one which can be enqueued or executed even if this call has already been executed.
