Interface OrElseBlock

All Superinterfaces:
MultiverseConstants
All Known Implementing Classes:
GammaOrElseBlock
public interface OrElseBlock extends MultiverseConstants
The OrElse is responsible for executing the either block, or in case of a retry, the orelse block is executed.

Another useful features of this design is that for certain primitives it doesn't require any form of boxing. It also provides an atomicChecked for a TxnVoidCallable which doesn't force a developer to return something when nothing needs to be returned.

  • Method Details

    • execute

      <E> E execute(TxnCallable<E> either, TxnCallable<E> orelse)
      Executes the either, or when it is retried, the orelse block. This operation makes composable blocking operations possible.

      If in the execution of the closure a checked exception is thrown, the exception is wrapped in a InvisibleCheckedException. The original exception can be retrieved by calling the getCause method.

      Parameters:
      either -
      orelse -
      Returns:
      the result of the execution.
      Throws:
      NullPointerException - if either or orelse is null.
      TxnMandatoryException - if no transaction is found on the TxnThreadLocal.
      InvisibleCheckedException - if a checked exception is thrown by the closure.

    • executeChecked

      <E> E executeChecked(TxnCallable<E> either, TxnCallable<E> orelse) throws Exception
      Executes the either, or when it is retried, the orelse block. This operation makes composable blocking operations possible.
      Parameters:
      either -
      orelse -
      Returns:
      the result of the execution.
      Throws:
      NullPointerException - if either or orelse is null.
      TxnMandatoryException - if no transaction is found on the TxnThreadLocal.
      Exception - if the atomicChecked call fails.

    • execute

      int execute(TxnIntCallable either, TxnIntCallable orelse)
      Executes the either, or when it is retried, the orelse block. This operation makes composable blocking operations possible.

      If in the execution of the closure a checked exception is thrown, the exception is wrapped in a InvisibleCheckedException. The original exception can be retrieved by calling the getCause method.

      Parameters:
      either -
      orelse -
      Returns:
      the result of the execution.
      Throws:
      NullPointerException - if either or orelse is null.
      TxnMandatoryException - if no transaction is found on the TxnThreadLocal.
      InvisibleCheckedException - if a checked exception is thrown by the closure.

    • executeChecked

      int executeChecked(TxnIntCallable either, TxnIntCallable orelse) throws Exception
      Executes the either, or when it is retried, the orelse block. This operation makes composable blocking operations possible.
      Parameters:
      either -
      orelse -
      Returns:
      the result of the execution.

    • execute

      long execute(TxnLongCallable either, TxnLongCallable orelse)
      Executes the either, or when it is retried, the orelse block. This operation makes composable blocking operations possible.

      If in the execution of the closure a checked exception is thrown, the exception is wrapped in a InvisibleCheckedException. The original exception can be retrieved by calling the getCause method.

      Parameters:
      either -
      orelse -
      Returns:
      the result of the execution.

    • executeChecked

      long executeChecked(TxnLongCallable either, TxnLongCallable orelse) throws Exception
      Executes the either, or when it is retried, the orelse block. This operation makes composable blocking operations possible.
      Parameters:
      either -
      orelse -
      Returns:
      the result of the execution.

    • execute

      double execute(TxnDoubleCallable either, TxnDoubleCallable orelse)
      Executes the either, or when it is retried, the orelse block. This operation makes composable blocking operations possible.

      If in the execution of the closure a checked exception is thrown, the exception is wrapped in a InvisibleCheckedException. The original exception can be retrieved by calling the getCause method.

      Parameters:
      either -
      orelse -
      Returns:
      the result of the execution.

    • executeChecked

      double executeChecked(TxnDoubleCallable either, TxnDoubleCallable orelse) throws Exception
      Executes the either, or when it is retried, the orelse block. This operation makes composable blocking operations possible.
      Parameters:
      either -
      orelse -
      Returns:
      the result of the execution.

    • execute

      boolean execute(TxnBooleanCallable either, TxnBooleanCallable orelse)
      Executes the either, or when it is retried, the orelse block. This operation makes composable blocking operations possible.

      If in the execution of the closure a checked exception is thrown, the exception is wrapped in a InvisibleCheckedException. The original exception can be retrieved by calling the getCause method.

      Parameters:
      either -
