Member Function Documentation

◆ GetDuration() [1/2]

static std::chrono::microseconds r_code::Utils::GetDuration ( const Atom * iptr )

inlinestatic

Interpret iptr[1] and iptr[2] as an signed 64-bit integer and return it as a duration. This assumes that the caller has already checked iptr[0] == Atom::DURATION, if needed.

Parameters

iptr	A pointer into the Atom array.

Returns: The duration.

Definition at line 242 of file r_code/utils.h.

◆ GetDuration() [2/2]

template<class O >

static std::chrono::microseconds r_code::Utils::GetDuration	(	const O *	object,
		uint16	index
	)

inlinestatic

Get the duration pointed to by the I_PTR at index. This assumes that the caller has already checked that the code pointed to is Atom::DURATION, if needed.

Parameters

object	The object with the Code array.
index	The index in the Code array of the I_PTR to the duration structure (like SetDuration<Code>() but not the index of the duration structure itself as in SetDurationStruct()).

Returns: The duration.

Definition at line 274 of file r_code/utils.h.

◆ GetInt64()

static int64 r_code::Utils::GetInt64	(	const Atom *	code,
		size_t	index
	)

inlinestatic

Get the signed 64-bit integer at code[index] and code[index + 1].

Parameters

code	The Atom array.
index	The index in code of the first uint32 value.

Returns: The signed 64-bit integer.

Definition at line 138 of file r_code/utils.h.

◆ GetTimestamp() [1/2]

Timestamp r_code::Utils::GetTimestamp ( const Atom * iptr )

static

Interpret iptr[1] and iptr[2] as an signed 64-bit integer and return it as time stamp. This assumes that the caller has already checked iptr[0] == Atom::TIMESTAMP, if needed.

Parameters

iptr	A pointer into the Atom array.

Returns: The time stamp.

Definition at line 129 of file code_utils.cpp.

◆ GetTimestamp() [2/2]

template<class O >

static Timestamp r_code::Utils::GetTimestamp	(	const O *	object,
		uint16	index
	)

inlinestatic

Get the time stamp pointed to by the I_PTR at index.

Parameters

object	The object with the Code array.
index	The index in the Code array of the I_PTR to the time stamp structure (like SetTimestamp<Code>() but not the index of the time stamp structure itself as in SetTimestampStruct()).

Returns: The time stamp.

Definition at line 204 of file r_code/utils.h.

◆ has_reference()

bool r_code::Utils::has_reference	(	const Atom *	code,
		uint16	index
	)

static

Check the code at index has a reference, also following I_PTR and recursing into sets.

Parameters

code	The code to check.
index	start checking at code[index].

Returns: True if the element has a reference.

Definition at line 254 of file code_utils.cpp.

◆ SetDuration() [1/2]

static void r_code::Utils::SetDuration	(	Atom *	iptr,
		std::chrono::microseconds	duration
	)

inlinestatic

Set iptr[0] to Atom::Duration() and set iptr[1] and iptr[2] to the signed 64-bit value of the duration.

Parameters

iptr	A pointer into the Atom array.
duration	The duration.

Definition at line 251 of file r_code/utils.h.

◆ SetDuration() [2/2]

template<class O >

static void r_code::Utils::SetDuration	(	O *	object,
		uint16	index,
		std::chrono::microseconds	duration
	)

inlinestatic

Set the Code array values at index with the structure for the duration.

Parameters

object	The object with the Code array.
index	The index in the Code array of the I_PTR to the duration structure (like GetDuration() but not the index of the time stamp structure itself as in SetDurationStruct()).
duration	The duration to put in the structure at the index.

Definition at line 287 of file r_code/utils.h.

◆ SetDurationStruct()

void r_code::Utils::SetDurationStruct	(	Code *	object,
		uint16	index,
		std::chrono::microseconds	duration
	)

static

Set the Code array values at index with the structure for the duration.

Parameters

object	The object with the Code array. This expands object->code to allocate atoms.
index	The index in the Code array to place the duration structure (not the index of the I_PTR to the structure as in SetDuration<Code>() or GetDuration()).
duration	The duration to put in the structure at the index.

Definition at line 168 of file code_utils.cpp.

◆ SetInt64()

static void r_code::Utils::SetInt64	(	Atom *	code,
		size_t	index,
		int64	value
	)

inlinestatic

Set the uint32 values at code[index] and code[index + 1] to the big-endian of value.

Parameters

code	The Atom array. You must make sure the array has room up to code[index + 1].
index	The index in code for the first uint32 value.
value	The signed 64-bit integer to set.

Definition at line 149 of file r_code/utils.h.

◆ SetTimestamp() [1/2]

void r_code::Utils::SetTimestamp	(	Atom *	iptr,
		Timestamp	timestamp
	)

static

Set iptr[0] to Atom::Timestamp() and set iptr[1] and iptr[2] to the signed 64-bit value of the time stamp.

Parameters

iptr	A pointer into the Atom array.
timestamp	The time stamp.

Definition at line 134 of file code_utils.cpp.

◆ SetTimestamp() [2/2]

template<class O >

static void r_code::Utils::SetTimestamp	(	O *	object,
		uint16	index,
		Timestamp	timestamp
	)

inlinestatic

Set the Code array values at index with the structure for the timestamp.

Parameters

object	The object with the Code array.
index	The index in the Code array of the I_PTR to the time stamp structure (like GetTimestamp() but not the index of the time stamp structure itself as in SetTimestampStruct()).
timestamp	The time stamp to put in the structure at the index.

Definition at line 217 of file r_code/utils.h.

◆ SetTimestampStruct()

void r_code::Utils::SetTimestampStruct	(	Code *	object,
		uint16	index,
		Timestamp	timestamp
	)

static

Set the Code array values at index with the structure for the timestamp.

Parameters

object	The object with the Code array.
index	The index in the Code array to place the time stamp structure (not the index of the I_PTR to the structure as in SetTimestamp<Code>() or GetTimestamp()).
timestamp	The time stamp to put in the structure at the index.

Definition at line 140 of file code_utils.cpp.

◆ ToString_s_ms_us()

string r_code::Utils::ToString_s_ms_us	(	Timestamp	timestamp,
		Timestamp	time_reference
	)

static

Make a string from (timestamp - time_reference) in the form XXXs:YYYms:ZZZus, with a minus sign if it is negative.

Parameters

timestamp	The time stamp.
time_reference	The reference time to subtract from timestamp, usually the session start time. We do this because timestamp is seconds since 01/01/1970, so the seconds would be very large.

Returns: The formatted time string.

Definition at line 148 of file code_utils.cpp.

◆ ToString_us()

string r_code::Utils::ToString_us ( std::chrono::microseconds duration )

static

Make a string from duration in the form XXXus, with a minus sign if it is negative. However if the microseconds portion is zero, then use YYYms. Or if the microseconds and milliseconds portions are zero, then use ZZZs. (This is the complement to how the compiler parses durations.)

Parameters

duration The duration.

Returns: The formatted time string.
