override |
Default destructor.
Member Function Documentation
◆ clearMxSectionData()
| void ml::R2SonicWC::WaterColumnM1OrM2::clearMxSectionData | ( | ) | const |
Unload magnitude and/or phase data from arrays and really try to unmap the array memory.
◆ getAsString()
| std::string ml::R2SonicWC::WaterColumnM1OrM2::getAsString | ( | const MLint | maxBeams = -1, |
| const MLint | maxSamplesPerBeam = -1, | ||
| std::string | prefix = "", | ||
| const std::string & | sep = " " ) const |
See WaterColumnDataSet.getAsString for documentation.
◆ getSectionName()
|
overridevirtual |
Get name of section as std::string.
Implements ml::R2SonicWC::WaterColumnSectionBase.
◆ mapMxSectionData()
| void ml::R2SonicWC::WaterColumnM1OrM2::mapMxSectionData | ( | ) | const |
Actually load the M1/M2 section data.
◆ read()
| MLuint64 ml::R2SonicWC::WaterColumnM1OrM2::read | ( | R2SonicWCLoader & | reader, |
| MLuint64 & | fileReadPos ) |
Read section from a file with help of ByteDataReader reader and increase fileReadPos appropriately.
◆ reset()
|
overridevirtual |
Resets all members to construction state.
Reimplemented from ml::R2SonicWC::WaterColumnSectionBase.
◆ unmapMxSectionDataHint()
| void ml::R2SonicWC::WaterColumnM1OrM2::unmapMxSectionDataHint | ( | ) | const |
If memory saving mode is enabled then unload magnitude and/or phase data from arrays; may be ignored if memory saving is off.
Member Data Documentation
◆ _reader
|
mutableprotected |
Pointer to the reader which loaded this file; it must (and must be valid during entire life time) to be able to perform a delayed (un/re)load of magnitude and/or phase data.
Otherwise we have no chance to limit memory usage on large files.
Definition at line 255 of file mlWaterColumnStructures.h.
◆ fileDataReadPos
| MLuint64 ml::R2SonicWC::WaterColumnM1OrM2::fileDataReadPos |
Location of M1/M2 data in file.
Definition at line 228 of file mlWaterColumnStructures.h.
◆ m1OrM2CommonHeader
| WaterColumnM1AndM2Header ml::R2SonicWC::WaterColumnM1OrM2::m1OrM2CommonHeader |
Common part of M1 and M2 section data.
Definition at line 225 of file mlWaterColumnStructures.h.
◆ magnitudeData
|
mutable |
Values 0 to 65535 map non-linearly (due to TVG scaling and possible gain compression) to signal amplitude magnitude data (typical example: 256 beams each containing 36 two-byte structs, 16 kilobytes) 16-bit magnitude data (present only during "magnitude-only" water column data mode, many per ping, you assemble them into complete ping data)
size=M1_Beams*M1_Samples if in M1 mode, otherwise empty.
Definition at line 234 of file mlWaterColumnStructures.h.
◆ magnitudePhaseData
|
mutable |
Magnitude and phase data (typical example: 256 beams each containing 36 four-byte structs, 36 kilobytes) 16-bit magnitude and phase data (present only during "magnitude and phase" water column data mode, many per ping, you assemble them into complete ping data)
size=M1_Beams*M1_Samples if in M2 mode, otherwise empty.
Definition at line 246 of file mlWaterColumnStructures.h.
◆ saveMemory
| bool ml::R2SonicWC::WaterColumnM1OrM2::saveMemory |
Flag to indicate whether memory save mode is enabled or not.
Definition at line 249 of file mlWaterColumnStructures.h.
