Enumeration Type Documentation

enum ROOT::EAxisCompatibility

strong

Enumerator
kIdentical	Source and target axes are identical.
kContains	The source is a subset of bins of the target axis.
kSampling	The bins of the source axis have finer granularity, but the bin borders are compatible. Example: source: 0., 1., 2., 3., 4., 5., 6.; target: 0., 2., 5., 6. Note that this is not a symmetrical property: only one of CanMerge(source, target), CanMap(target, source) can return kContains.
kIncompatible	The source axis and target axis have different binning. Example: source: 0., 1., 2., 3., 4., target: 0., 0.1, 0.2, 0.3, 0.4

template<typename T >

EFromHumanReadableSize ROOT::FromHumanReadableSize	(	std::string_view	str,
		T &	value
	)

Convert strings like the following into byte counts 5MB, 5 MB, 5M, 3.7GB, 123b, 456kB, 3.7GiB, 5MiB with some amount of forgiveness baked into the parsing.

For this routine we use the official SI unit where the [i] is reserved for the 'legacy' power of two units. 1KB = 1000 bytes, 1KiB = 1024 bytes.

Parameters

str	the string to be parsed
value	will be updated with the result if and only if the parse is sucessfull and does not overflow for the type of value.

Returns: return a EFromHumanReadableSize enum value indicating the success or failure of the parse.
