Detailed Description

template<typename THandle, typename TStruct, int16_t size>
class wpi::hal::DigitalHandleResource< THandle, TStruct, size >

The DigitalHandleResource class is a way to track handles.

This version allows a limited number of handles that are allocated by index. The enum value is separate, as 2 enum values are allowed per handle Because they are allocated by index, each individual index holds its own mutex, which reduces contention heavily.

Template Parameters

THandle	The Handle Type (Must be typedefed from HAL_Handle)
TStruct	The struct type held by this resource
size	The number of resources allowed to be allocated
