Method Details [hide private]

__init__(self, location=None, allowRepeatedKeys=True)
(Constructor)

source code 

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Parameters:
  • location (str) - (Optional) Location of the crash database. If no location is specified, the container is volatile.

    If the location is a filename, it's an SQLite database file.

    Volatile containers are stored only in memory and destroyed when they go out of scope.

  • allowRepeatedKeys (bool) - If True all Crash objects are stored.

    If False any Crash object with the same key as a previously existing object will be ignored.

Overrides: object.__init__

add(self, crash)

source code 

Adds a new crash to the container.

Parameters:
  • crash (Crash) - Crash object to add.

Note: When the allowRepeatedKeys parameter of the constructor is set to False, duplicated crashes are ignored.

See Also: Crash.key

__iter__(self)

source code 
Returns: iterator
Iterator of the contained Crash objects.

__contains__(self, crash)
(In operator)

source code 
Parameters:
  • crash (Crash) - Crash object.
Returns: bool
True if the Crash object is in the container.

__len__(self)
(Length operator)

source code 
Returns: int
Count of Crash elements in the container.

__bool__(self)

source code 
Returns: bool
False if the container is empty.

__marshall_key(self, key)

source code 

Marshalls a Crash key to be used in the database.

Parameters:
  • key ((opaque object)) - Key to convert.
Returns: BLOB
Converted key.

__unmarshall_key(self, key)

source code 

Unmarshalls a Crash key read from the database.

Parameters:
  • key (str) - Key to convert.
Returns: (opaque object)
Converted key.

__marshall_value(self, value)

source code 

Marshalls a Crash object to be used in the database. The memoryMap member is NOT stored here.

Parameters:
  • value (Crash) - Object to convert.
Returns: BLOB
Converted object.

__unmarshall_value(self, value)

source code 

Unmarshalls a Crash object read from the database.

Parameters:
  • value (str) - Object to convert.
Returns: Crash
Converted object.
