CArchiveStreamBase< STREAM > archiveFrom(STREAM &s)
Helper function to create a templatized wrapper CArchive object for a: MRPT&#39;s CStream, std::istream, std::ostream, std::stringstream.
Definition: CArchive.h:592
This CStream derived class allow using a memory buffer as a CStream.
#define DECLARE_TTYPENAME_CLASSNAME(_CLASSNAME)
Like DECLARE_CUSTOM_TTYPENAME(), but for use within the class declaration body.
Definition: TTypeName.h:104
uint64_t Seek(int64_t Offset, CStream::TSeekOrigin Origin=sFromBeginning) override
Introduces a pure virtual method for moving to a specified position in the streamed resource...
CArchive & operator>>(CArchive &s, mrpt::aligned_std_vector< float > &a)
Definition: CArchive.cpp:250
Virtual base class for "archives": classes abstracting I/O streams.
Definition: CArchive.h:54
EXPECT_EQ(out.image_pair_was_used.size(), NUM_IMGS)
CArchive & operator<<(CArchive &s, const mrpt::aligned_std_vector< float > &a)
Definition: CArchive.cpp:199
