class BinaryDataNotification:
	"""
	``class BinaryDataNotification`` provides an interface for receiving event notifications. Usage requires inheriting
	from this interface, overriding the relevant event handlers, and registering the `BinaryDataNotification` instance
	with a `BinaryView` using the `register_notification` method.

	By default, a `BinaryDataNotification` instance receives notifications for all available notification types. It
	is recommended for users of this interface to initialize the `BinaryDataNotification` base class with specific
	callbacks of interest by passing the appropriate `NotificationType` flags into the `__init__` constructor.

	Handlers provided by the user should aim to limit the amount of processing within the callback. The
	callback context holds a global lock, preventing other threads from making progress during the callback phase.
	While most of the API can be used safely during this time, care must be taken when issuing a call that can block,
	as waiting for a thread requiring the global lock can result in deadlock.

	The `NotificationBarrier` is a special `NotificationType` that is disabled by default. To enable it, the
	`NotificationBarrier` flag must be passed to `__init__`. This notification is designed to facilitate efficient
	batch processing of other notification types. The idea is to collect other notifications of interest into a cache,
	which can be very efficient as it doesn't require additional locks. After some time, the core generates a
	`NotificationBarrier` event, providing a safe context to move the cache for processing by a different thread.

	To control the time of the next `NotificationBarrier` event, return the desired number of milliseconds until
	the next event from the `NotificationBarrier` callback. Returning zero quiesces future `NotificationBarrier`
	events. If the `NotificationBarrier` is quiesced, the reception of a new callback of interest automatically
	generates a new `NotificationBarrier` call after that notification is delivered. This mechanism effectively
	allows throttling and quiescing when necessary.

	.. note:: Note that the core generates a `NotificationBarrier` as part of the `BinaryDataNotification` registration \
	process. Registering the same `BinaryDataNotification` instance again results in a gratuitous `NotificationBarrier` \
	event, which can be useful in situations requiring a safe context for processing due to some other asynchronous \
	event (e.g., user interaction).

	:Example:

	>>> class NotifyTest(binaryninja.BinaryDataNotification):
	... 	def __init__(self):
	... 		super(NotifyTest, self).__init__(binaryninja.NotificationType.NotificationBarrier | binaryninja.NotificationType.FunctionLifetime | binaryninja.NotificationType.FunctionUpdated)

class MemoryMap:
	r"""
	The MemoryMap object is used to describe a system level MemoryMap for which a BinaryView is loaded into. A loaded
	BinaryView has a view into the MemoryMap which is described by the Segments defined in that BinaryView. The MemoryMap
	object allows for the addition of multiple, arbitrary overlapping regions of memory. Segmenting of the address space is
	automatically handled when the MemoryMap is modified and in the case where a portion of the system address space has
	multiple defined regions, the default ordering gives priority to the most recently added region. This feature is
	experimental and under active development.

		- `bytes` or `bytearray`: Directly loaded into memory as a `DataMemoryRegion`.

class BinaryView:
	"""
	``class BinaryView`` implements a view on binary data, and presents a queryable interface of a binary file. One key
	job of BinaryView is file format parsing which allows Binary Ninja to read, write, insert, remove portions
	of the file given a virtual address. For the purposes of this documentation we define a virtual address as the
	memory address that the various pieces of the physical file will be loaded at.

	A binary file does not have to have just one BinaryView, thus much of the interface to manipulate disassembly exists
	within or is accessed through a BinaryView. All files are guaranteed to have at least the ``Raw`` BinaryView. The
	``Raw`` BinaryView is simply a hex editor, but is helpful for manipulating binary files via their absolute addresses.

	BinaryViews are plugins and thus registered with Binary Ninja at startup, and thus should **never** be instantiated
	directly as this is already done. The list of available BinaryViews can be seen in the BinaryViewType class which
	provides an iterator and map of the various installed BinaryViews::

		>>> list(BinaryViewType)
		[<view type: 'Raw'>, <view type: 'ELF'>, <view type: 'Mach-O'>, <view type: 'PE'>]
		>>> BinaryViewType['ELF']
		<view type: 'ELF'>

	To open a file with a given BinaryView the following code is recommended:

		>>> with load("/bin/ls") as bv:
		...   bv
		<BinaryView: '/bin/ls', start 0x100000000, len 0x142c8>

	`By convention in the rest of this document we will use bv to mean an open and, analyzed, BinaryView of an executable file.`
	When a BinaryView is open on an executable view analysis is automatically run unless specific named parameters are used
	to disable updates. If such a parameter is used, updates can be triggered using the :py:func:`update_analysis_and_wait` method
	which disassembles the executable and returns when all disassembly and analysis is complete::

		>>> bv.update_analysis_and_wait()
		>>>

	Since BinaryNinja's analysis is multi-threaded (depending on version) this can also be done in the background
	by using the :py:func:`update_analysis` method instead.

	By standard python convention methods which start with '_' should be considered private and should not
	be called externally. Additionally, methods which begin with ``perform_`` should not be called directly
	either and are used explicitly for subclassing a BinaryView.

	.. note:: An important note on the ``*_user_*()`` methods. Binary Ninja makes a distinction between edits \
	performed by the user and actions performed by auto analysis. Auto analysis actions that can quickly be recalculated \
	are not saved to the database. Auto analysis actions that take a long time and all user edits are stored in the \
	database (e.g. :py:func:`remove_user_function` rather than :py:func:`remove_function`). Thus use ``_user_`` methods if saving \
	to the database is desired.

		Evaluates a string expression to an integer value.

		The parser uses the following rules:

			- Symbols are defined by the lexer as ``[A-Za-z0-9_:<>][A-Za-z0-9_:$\-<>]+`` or anything enclosed in either single or double quotes
			- Symbols are everything in ``bv.symbols``, unnamed DataVariables (i.e. ``data_00005000``), unnamed functions (i.e. ``sub_00005000``), or section names (i.e. ``.text``)
			- Numbers are defaulted to hexadecimal thus `_printf + 10` is equivalent to `printf + 0x10` If decimal numbers required use the decimal prefix.
			- Since numbers and symbols can be ambiguous its recommended that you prefix your numbers with the following:

				- ``0x`` - Hexadecimal
				- ``0n`` - Decimal
				- ``0`` - Octal

			- In the case of an ambiguous number/symbol (one with no prefix) for instance ``12345`` we will first attempt
			  to look up the string as a symbol, if a symbol is found its address is used, otherwise we attempt to convert
			  it to a hexadecimal number.
			- The following operations are valid: ``+, -, \*, /, %, (), &, \|, ^, ~, ==, !=, >, <, >=, <=``

				- Comparison operators return 1 if the condition is true, 0 otherwise.

			- In addition to the above operators there are dereference operators similar to BNIL style IL:

				- ``[<expression>]`` - read the `current address size` at ``<expression>``
				- ``[<expression>].b`` - read the byte at ``<expression>``
				- ``[<expression>].w`` - read the word (2 bytes) at ``<expression>``
				- ``[<expression>].d`` - read the dword (4 bytes) at ``<expression>``
				- ``[<expression>].q`` - read the quadword (8 bytes) at ``<expression>``

			- The ``$here`` (or more succinctly: ``$``) keyword can be used in calculations and is defined as the ``here`` parameter, or the currently selected address
			- The ``$start``/``$end`` keyword represents the address of the first/last bytes in the file respectively
			- Arbitrary magic values (name-value-pairs) can be added to the expression parser via the
			  :py:func:`add_expression_parser_magic_value` API. Notably, the debugger adds all register values into the
			  expression parser so they can be used directly when navigating. The register values can be referenced like
			  `$rbp`, `$x0`, etc. For more details, refer to the related
			  `debugger docs <https://docs.binary.ninja/guide/debugger/index.html#navigating-the-binary>`_.
