| Summary : Restricted, ordered hashes as arrays tied to a \"type\" (shared list of keys)
|
Description :
An instance of \'Hash::Type\' encapsulates a collection of field names, and
is used to generate tied hashes, implemented internally as arrayrefs, and
sharing the common list of fields.
The original motivation for this design was to spare memory, since the
field names are shared. As it turns out, benchmarks show that this goal is
not attained : memory usage is about 35% higher than Perl native hashes.
However, this module also implements *restricted hashes* (hashes with a
fixed set of keys that cannot be expanded) and of *ordered hashes* (the
list of keys or list values are returned in a fixed order); and for those
two functionalities, the performances of \'Hash::Type\' are very competitive
with respect to those of other similar modules, both in terms of CPU and
memory usage (see the \"BENCHMARKS\" section at the end of the
documentation). In addition, \'Hash::Type\' offers an API for *convenient and
very efficient sorting* of lists of tied hashes, and alternative methods
for \'keys\', \'values\' and \'each\', faster than the perltie API.
In conclusion, this module is well suited for any need of restricted and/or
ordered hashes, and for situations dealing with large collections of
homogeneous hashes, like for example data rows coming from spreadsheets or
databases.
