- in some circumstances we need to pass a bool value upwards to the
caller and know if the true/false value was set based on real input
or is a default value.
Eg, in the object::read() we might normally have
enabled_(dict.readIfPresent(key, true));
but would lose information about why the value is true/false.
We can change that by using
enabled_(dict.readIfPresent<Switch>(key, Switch::DEFAULT_ON));
After which we can use this information is testing.
if
(
child.enabled().nonDefault()
? child.enabled()
: parent.enabled()
)
{ ... }
And thus enable output if the parent requested it explicitly or by
default and it has not been explicitly disabled in the child.
No difference when testing as a bool and the text representation
of DEFAULT_ON / DEFAULT_OFF will simply be "true" / "false".
ENH: add construction of Switch from dictionary (similar to Enum)
- similar to word::validate to allow stripping of invalid characters
without triggering a FatalError.
- use this validated fileName in Foam::readDir to avoid problems when
a directory contains files with invalid characters in their names
- adjust rmDir to handle filenames with invalid characters
- fileName::equals() static method to compare strings while ignoring
any differences that are solely due to duplicate slashes
- The problem occurs when using atof to parse values such as "1e-39"
since this is out of range for a float and _can_ set errno to
ERANGE.
Similar to parsing of integers, now parse with the longest floating
point representation "long double" via strtold (guaranteed to be
part of C++11) and verify against the respective VGREAT values for
overflow. Treat anything smaller than VSMALL to be zero.
- used in various places to test if the input can be parsed as a
label/scalar, so warnings tend to flood the output.
- be more explicit when encountering range errors
- Any trailing whitespace when parsing from strings or character buffers
is ignored rather than being treated as an error. This is consistent
with behaviour when reading from an Istream and with leading whitespace
being ignored in the underlying atof/atod, strtof/strtod... functions.
- Allow parsing directly from a std::string instead of just from a 'char*'.
This reflects the C++11 addition of std::stod to complement the C
functions strtod. This also makes it easier to parse string directly
without using an IStringStream.
- Two-parameter parsing methods return success/failure.
Eg,
if (readInt32(str, &int32Val)) ...
- One-parameter parsing methods return the value on success or
emit a FatalIOError.
Eg,
const char* buf;
int32Val = readInt32(buf, &);
- Improved consistency when parsing unsigned ints.
Use strtoimax and strtoumax throughout.
- Rename readDoubleScalar -> readDouble, readFloatScalar -> readFloat.
Using the primitive name directly instead of the Foam typedef for
better consistency with readInt32 etc.
- Clean/improve parseNasScalar.
Handle normal numbers directly, reduce some operations.
