- this is principally for cases where reduced indentation is desired,
such as when streaming to a memory location. If the indentation size
is zero or one, only a single space will be used to separate the
key/value.
This change does not affect the stream allocation size, since the
extra data falls within the padding.
ENH: relocate label/scalar sizes from Istream to IOstream.
- could allow future use for output streams as well?
Due to padding, reorganization has no effect on allocated size
of output streams.
STYLE: add read/write name qualifier to beginRaw, endRaw
- removes ambiguity for bi-directional streams
STYLE: fix inconsistent 'const' qualifier on std::streamsize
- base Ostream was without const, some derived streams with const
- allows full recovery of allocated space, not just addressable range.
This can be particularly useful for code patterns that repeatedly
reuse the same buffer space. For example,
DynamicList<char> buf(1024);
// some loop
{
OListStream os(std::move(buf));
os << ...
os.swap(buf);
}
Can read back from this buffer as a second operation:
{
UIListStream is(buf);
is >> ...
}
This class is largely a pre-C++11 holdover. It is now possible to
simply use move construct/assignment directly.
In a few rare cases (eg, polyMesh::resetPrimitives) it has been
replaced by an autoPtr.
- more consistent naming:
* Versions that hold and manage their own memory:
IListStream, OListStream
* Versions that reference a fixed size external memory:
UIListStream, UOListStream
- use List storage instead of DynamicList within OListStream.
Avoids duplicate bookkeeping, more direct handling of resizing.
