SchemaRequestTask

Overview

This class is an inheritor of RequestTask and is returned as a result of RemoteDataAdapter calls. It has a ""getSchema` method that provides a task result.

constructor (Callable<Schema>, Callback)  protected

 

constructor(aCallable: Callable<Schema>; aCallback: Callback)

 

SchemaRequestTask(Callable<Schema> aCallable, Callback aCallback)

Parameters:

  • aCallable:
  • aCallback:

constructor (Callable<Schema>, Callback)  protected    (declared in RequestTask<TResult,TCallback>)

 

constructor(aCallable: Callable<Schema>; aCallback: Callback)

 

SchemaRequestTask(Callable<Schema> aCallable, Callback aCallback)

Parameters:

  • aCallable:
  • aCallback:

constructor (Runnable, Schema, Callback)  protected    (declared in RequestTask<TResult,TCallback>)

 

constructor(aRunnable: Runnable; aResult: Schema; aCallback: Callback)

 

SchemaRequestTask(Runnable aRunnable, Schema aResult, Callback aCallback)

Parameters:

  • aRunnable:
  • aResult:
  • aCallback:

CallbackExecutor    (declared in RequestTask<TResult,TCallback>)

 

property CallbackExecutor: Executor read write;

 

Executor CallbackExecutor { __get; __set; }

cancel    (declared in RequestTask<TResult,TCallback>)

Attempts to cancel execution of this task. This attempt will fail if the task has already completed, already been cancelled, or could not be cancelled for some other reason. If successful, and this task has not started when cancel is called, this task should never run. If the task has already started, then the mayInterruptIfRunning parameter determines whether the thread executing this task should be interrupted in an attempt to stop the task.

 

method cancel(mayInterruptIfRunning: Boolean): Boolean

 

Boolean cancel(Boolean mayInterruptIfRunning)

Parameters:

  • mayInterruptIfRunning: TRUE if the thread executing this task should be interrupted; otherwise, in-progress tasks are allowed to complete

execute    (declared in RequestTask<TResult,TCallback>)

Executes the given command at some time in the future. The command may execute in a new thread, in a pooled thread, or in the calling thread, at the discretion of the Executor implementation.

 

method execute: RequestTask<TResult, TCallback>

 

RequestTask<TResult, TCallback> execute()

Executor    (declared in RequestTask<TResult,TCallback>)

 

property Executor: Executor read write;

 

Executor Executor { __get; __set; }

FailureCause    (declared in RequestTask<TResult,TCallback>)

 

property FailureCause: Throwable read write;

 

Throwable FailureCause { __get; __set; }

get    (declared in RequestTask<TResult,TCallback>)

Waits if necessary for the computation to complete, and then retrieves its result.

 

method get: Schema

 

Schema get()

get (Long, TimeUnit): Schema    (declared in RequestTask<TResult,TCallback>)

Waits if necessary for at most the given time for the computation to complete, and then retrieves its result, if available.

 

method get(aTimeout: Long; aUnit: TimeUnit): Schema

 

Schema get(Long aTimeout, TimeUnit aUnit)

Parameters:

  • aTimeout: the maximum time to wait

isCancelled    (declared in RequestTask<TResult,TCallback>)

Returns TRUE if this task was cancelled before it completed normally.

 

method isCancelled: Boolean
