Detailed Description
Priority Set of up to 64 elements for building various schedulers, but also useful as a general set of up to 64 elements of any kind.
The priority set represents the set of active objects that are ready to run and need to be considered by scheduling processing. The set is capable of storing up to 64 priority levels.
The priority set allows to build cooperative multitasking schedulers to manage up to 64 tasks. It is also used in the Quantum Kernel (QK) preemptive scheduler.
The inherited 8-bit set is used as the 8-elemtn set of of 8-bit subsets Each bit in the super.bits set represents a subset (8-elements) as follows:
bit 0 in this->m_bits is 1 when subset[0] is not empty
bit 1 in this->m_bits is 1 when subset[1] is not empty
bit 2 in this->m_bits is 1 when subset[2] is not empty
bit 3 in this->m_bits is 1 when subset[3] is not empty
bit 4 in this->m_bits is 1 when subset[4] is not empty
bit 5 in this->m_bits is 1 when subset[5] is not empty
bit 6 in this->m_bits is 1 when subset[6] is not empty
bit 7 in this->m_bits is 1 when subset[7] is not empty
