packed_dynamic_channel_reference
[Models]


Detailed Description

Represents a reference proxy to a channel operating over a bit range whose offset is specified at run time. Models ChannelConcept.

Example:

// Reference to a 2-bit channel whose offset is specified at construction time
typedef const packed_dynamic_channel_reference<uint8_t,2,true> bits2_dynamic_ref_t;

uint16_t data=0;
bits2_dynamic_ref_t channel_ref(&data,1);
channel_ref = channel_traits<bits2_dynamic_ref_t>::max_value();     // == 3
assert(data == 6);                                                  // == (3<<1) == 6


Classes

class  packed_dynamic_channel_reference< BitField, NumBits, false >
 Models a constant subbyte channel reference whose bit offset is a runtime parameter. Models ChannelConcept Same as packed_channel_reference, except that the offset is a runtime parameter. More...
class  packed_dynamic_channel_reference< BitField, NumBits, true >
 Models a mutable subbyte channel reference whose bit offset is a runtime parameter. Models ChannelConcept Same as packed_channel_reference, except that the offset is a runtime parameter. More...
