Detailed Description

Channel set. Multi-word bitmask with bits corresponding to enabled channels. Meaning of each channel is defined by ChannelLayout. Order of serialized channels is defined by ChannelOrder.

Definition at line 26 of file channel_set.h.

Constructor & Destructor Documentation

◆ ChannelSet() [1/2]

roc::audio::ChannelSet::ChannelSet ( )

Construct empty channel set.

◆ ChannelSet() [2/2]

roc::audio::ChannelSet::ChannelSet ( ChannelLayout  layout,
ChannelOrder  order,
ChannelMask  mask 
)

Construct with given layout and 32-bit channel mask.

Remarks
The mask defines only first 32 channels. All channels outside of 0-31 range will be disabled. If you need more channels, construct empty channel set and enable channels or channel ranges using setters.

Member Function Documentation

◆ bitwise_and()

void roc::audio::ChannelSet::bitwise_and ( const ChannelSet other)

Set channel set to result of bitwise AND operation with another set.

Remarks
Similar to "&=".

◆ bitwise_or()

void roc::audio::ChannelSet::bitwise_or ( const ChannelSet other)

Set channel set to result of bitwise OR operation with another set.

Remarks
Similar to "|=".

◆ bitwise_xor()

void roc::audio::ChannelSet::bitwise_xor ( const ChannelSet other)

Set channel set to result of bitwise XOR operation with another set.

Remarks
Similar to "^=".

◆ byte_at()

uint8_t roc::audio::ChannelSet::byte_at ( size_t  n) const

Get byte by index from bit mask.

◆ clear()

void roc::audio::ChannelSet::clear ( )

Unset all fields.

◆ first_channel()

size_t roc::audio::ChannelSet::first_channel ( ) const

Get index of first enabled channel.

Remarks
Panics if there are no enabled channels.

◆ has_channel()

bool roc::audio::ChannelSet::has_channel ( size_t  n) const

Check if specific channel is enabled.

◆ is_subset()

bool roc::audio::ChannelSet::is_subset ( ChannelMask  mask) const

Check if channel set is sub-set of given mask, or equal to it.

Remarks
The mask defines only first 32 channels. If any channels outside of 0-31 range are enabled in channel set, the method will fail.

◆ is_superset()

bool roc::audio::ChannelSet::is_superset ( ChannelMask  mask) const

Check if channel set is super-set of given mask, or equal to it.

Remarks
The mask defines only first 32 channels. If any channels outside of 0-31 range are enabled in channel set, the method will succeed.

◆ is_valid()

bool roc::audio::ChannelSet::is_valid ( ) const

Check if channel set has valid layout and order, and non-zero channels.

◆ last_channel()

size_t roc::audio::ChannelSet::last_channel ( ) const

Get index of last enabled channel.

Remarks
Panics if there are no enabled channels.

◆ layout()

ChannelLayout roc::audio::ChannelSet::layout ( ) const

Get channel layout.

Remarks
Defines meaning of channel numbers (e.g. that channel 0 is front-left).

◆ max_channels()

static size_t roc::audio::ChannelSet::max_channels ( )
static

Get maximum possible number of channels.

◆ num_bytes()

size_t roc::audio::ChannelSet::num_bytes ( ) const

Get number of bytes in bit mask.

◆ num_channels()

size_t roc::audio::ChannelSet::num_channels ( ) const

Get number of enabled channels.

◆ operator!=()

bool roc::audio::ChannelSet::operator!= ( const ChannelSet other) const

Check two channel sets for equality.

◆ operator==()

bool roc::audio::ChannelSet::operator== ( const ChannelSet other) const

Check two channel sets for equality.

◆ order()

ChannelOrder roc::audio::ChannelSet::order ( ) const

Get channel order.

Remarks
Defines order of serialized channels (e.g. that front-left goes before front-right).

◆ set_channel()

void roc::audio::ChannelSet::set_channel ( size_t  n,
bool  enabled 
)

Set given channel to be enabled or disabled.

◆ set_channel_mask()

void roc::audio::ChannelSet::set_channel_mask ( ChannelMask  mask)

Set enabled channels based on given mask.

Remarks
The mask defines only first 32 channels. All channels outside of 0-31 range will be disabled.

◆ set_channel_range()

void roc::audio::ChannelSet::set_channel_range ( size_t  from,
size_t  to,
bool  enabled 
)

Set all channels in inclusive range to be enabled or disabled.

◆ set_layout()

void roc::audio::ChannelSet::set_layout ( ChannelLayout  layout)

Set layout of the channel set.

◆ set_order()

void roc::audio::ChannelSet::set_order ( ChannelOrder  order)

Set order of the channel set.
