reven2.types._integer.BigEndian

class documentation

class BigEndian(Integer):

An integer type that wraps an inner integer type and forces its endianness to big-endian.

Method	`__init__`	Undocumented
Method	`__str__`	Returns the nicely printable string representation of this instance.
Method	`is_context_sensitive`	Whether the context argument needed by some methods actually has an effect.
Method	`size_bytes`	The minimal number of bytes necessary to hold an instance of this integer type.
Property	`endianness`	Property: The endianness of this integer type. Will always be big-endian.
Property	`inner`	Property: The inner integer type.
Property	`signedness`	Property: The signedness of this integer type.
Method	`_possible_sizes`	Undocumented
Instance Variable	`_integer_type`	Undocumented

Inherited from Integer:

Method	`__eq__`	Compares the instance for equality with an object.
Method	`__hash__`	Returns the hash for this value.
Method	`__ne__`	Compares the instance for equality with an object.
Method	`_construct_type`	Return the underlying `construct` instance

Inherited from Type (via Integer):

Method	`description`	The short description of this type.
Method	`parse`	Parses the value of an instance of this type from a raw buffer, possibly depending on the context.
Method	`to_bytes`	Build a byte buffer from a value of this type.
Method	`_resolve`	Uses the resolver to return a resolved version of the type, if possible.

def __init__(self, integer_type):

Undocumented

Parameters
integer_type:`Integer`	Undocumented

def __str__(self):

Returns the nicely printable string representation of this instance.

Returns
`str`	Undocumented

def is_context_sensitive(self):

overrides reven2.types._type.Type.is_context_sensitive

Whether the context argument needed by some methods actually has an effect.

Types that return False to this method are context-insensitive types. You can safely pass any object as context parameter (including None) to the methods of such type.

Note that the context-sensitivity of a type may change in the future.

Examples

Getting the size of a type without needing a context for context-insensitive types: >>> types.U32.is_context_sensitive() False >>> types.U32.size_bytes(context=None) 4 >>> array32_12 = types.Array(types.U32, 12) >>> array32_12.is_context_sensitive() False >>> array32_12.size_bytes() # context=None by default 48

Context-sensitive types may raise errors when attempting to get the size without a context: >>> types.USize.is_context_sensitive() True >>> types.USize.size_bytes(context=None) ValueError: Please provide a context when using a context-sensitive type

Returns
`bool`	Undocumented

def size_bytes(self, context=None):

overrides reven2.types._integer.Integer.size_bytes

The minimal number of bytes necessary to hold an instance of this integer type.

Information

Parameters
context:`_Optional[Context]`	The context object. See package documentation.
Returns
`int`	An `integer`.
