MPSGraphWhileBeforeBlock

The block that executes before the condition evaluates for each iteration.

Declaration

typealias MPSGraphWhileBeforeBlock = ([MPSGraphTensor], NSMutableArray) -> MPSGraphTensor

Parameters

  • inputTensors:

    Input tensors to the whileConditionBlock, for the first iteration will be same as initialInputs passed to the while loop.

  • resultTensors:

    A valid MPSGraphTensor array with results forwarded to after block or returned from the while loop depending on the predicate tensor. It will be empty and the caller block should fill it up before returning.

Return Value

Tensor MUST be set and have a single scalar value, used to decide between executing the body block or returning from the while loop.
