This file contains an abstract base class for serializing clash data AbstractClashDataSerializer.

AbstractClashDataSerializer Class#

class AbstractClashDataSerializer#

An abstract base class for serializing clash data.

This class defines the interface for clash data serialization and deserialization.

Any serializer must fully implement this abstract class.

Constructor#

__init__()

Initializes a new instance of the AbstractClashDataSerializer class.

Methods#

open(file_path_name: str) → None

The file path as a string.

Returns:

The file size in bytes.

data_structures_compatible() → bool#

Checks if the serializer has no compatibility issues with data structures or tables.

True if compatible, False otherwise.

deferred_file_creation_until_first_write_op() → bool#

Determines if file creation is postponed until the first write operation.

Returns:

True if file creation is deferred, False otherwise.

set_deferred_file_creation_until_first_write_op(value: bool)#

Sets whether file creation should be postponed until the first write operation.

Parameters:

value (bool) – True to enable deferred file creation, False otherwise.

Returns:

None

set_on_modified_fnc(on_modified_fnc: Callable[[str], None])#

Sets the function to be called when the file is modified.

Parameters:

on_modified_fnc (Callable[[str], None]) – The function to call on modification.

Returns:

None

on_modified_fnc#

Gets the function that is called when the file is modified.

Returns:

The function as a callable.

is_open() → bool

Checks if the serializer is ready for operations.

Returns:

True if the serializer is open, False otherwise.

save() → bool

Saves data to the target file.

Returns:

True if the data was successfully saved, False otherwise.

close() → None

Closes the opened file.

Returns:

None

commit() → None

Writes any unwritten data to the file. Committing bigger batches is advised.

Returns:

None
