# Class StatsCache

source code

An object instantiated as a singleton for each statsfile that provides access to the database cache from a pool of StatsCache objects.

Instance Methods | [hide private]

a new object with type S, a subtype of T

__new__(cls, statsfile=None) | source code

create(self) Create all tables and indexes. | source code

_getfileid(self, filename, check_mod_info=True, store=None) return fileid representing the given file in the statscache. | source code

_getstoredcheckerconfig(self, checker) See if this checker configuration has been used before. | source code

_cacheunitstats(self, units, fileid, unitindex=None, file_totals_record=FileTotals.new_record()) Cache the statistics for the supplied unit(s). | source code

Method Details | [hide private]

### __new__(cls, statsfile=None)

source code

Returns: a new object with type S, a subtype of T
Overrides: object.__new__
  (inherited documentation)

### create(self)

source code

Create all tables and indexes.

Decorators:
  - `@transaction`

### _getfileid(self, filename, check_mod_info=True, store=None)

source code

return fileid representing the given file in the statscache.

if file not in cache or has been updated since last record update, recalculate stats.

optional argument store can be used to avoid unnessecary reparsing of already loaded translation files.

store can be a TranslationFile object or a callback that returns one.

Decorators:
  - `@transaction`

### _cacheunitstats(self, units, fileid, unitindex=None, file_totals_record=FileTotals.new_record())

source code

Cache the statistics for the supplied unit(s).

Decorators:
  - `@transaction`

### _cachestore(self, store, realpath, mod_info)

source code

Calculates and caches the statistics of the given store unconditionally.

Decorators:
  - `@transaction`

### _cacheunitschecks(self, units, fileid, configid, checker, unitindex=None)

source code

Helper method for cachestorechecks() and recacheunit()

Decorators:
  - `@transaction`

### _cachestorechecks(self, fileid, store, checker, configid)

source code

Calculates and caches the error statistics of the given store unconditionally.

Decorators:
  - `@transaction`

### recacheunit(self, filename, checker, unit)

source code

Recalculate all information for a specific unit. This is necessary for updating all statistics when a translation of a unit took place, for example.

This method assumes that everything was up to date before (file totals, checks, checker config, etc.

Decorators:
  - `@transaction`

### _get_config_id(self, fileid, checker)

source code

Decorators:
  - `@transaction`

### unitstats(self, filename, _lang=None, store=None)

source code

Return a dictionary of property names mapping to arrays which map unit indices to property values.

Please note that this is different from filestats, since filestats supplies sets of unit indices with a given property, whereas this method supplies arrays which map unit indices to given values.
