Detailed Description

Holds the file formats of detector events that can be read, selects the most suitable of them for a file, and opens the file with it.

register_builtin_formats adds the formats bundled with the library, and register_format adds any other. get_shared is a selector that already holds the bundled ones.

Thread safety

Every method may be called concurrently.

Member Function Documentation

get_most_suitable_format()

const detector_event_timeline_file_read_format * vitrio::detector_event_timeline_file_read_format_selector::get_most_suitable_format

(

const image_file_probe &

probe

)

const

Get the format that would open a file, without opening it.

Parameters

probe

The file under consideration.

Returns

const detector_event_timeline_file_read_format* The most suitable format, or nullptr when none recognizes probe.

get_shared()

static const std::shared_ptr< detector_event_timeline_file_read_format_selector > & vitrio::detector_event_timeline_file_read_format_selector::get_shared ( )

static

Get the selector every use may share.

It holds the formats bundled with the library. A format registered on it is seen by everyone that shares it.

Returns

const std::shared_ptr<...>& The selector. Never null.

open()

std::shared_ptr< detector_event_timeline_reader > vitrio::detector_event_timeline_file_read_format_selector::open

(

const std::string &

path

)

const

Open a file for reading with the most suitable format.

Reads the head of the file once and shows it to every registered format, then opens the file with whichever reported the highest suitability.

Parameters

path	Path to the file to open, or any other locator a registered format claims, such as the address of a remote file.

Returns

std::shared_ptr<detector_event_timeline_reader> The opened reader, never null.

Exceptions

image_file_error	If no registered format claims the path and no readable file exists there.
unsupported_operation_error	If no registered format recognizes the file, which exists.
image_file_format_error	If the file is malformed or truncated.

register_format()

bool vitrio::detector_event_timeline_file_read_format_selector::register_format

(

std::unique_ptr< detector_event_timeline_file_read_format >

format

)

Register a new format.

Parameters

format

The format to be registered.

Returns

true The format was successfully registered.

false The format was null.
