reven2.types._integer.ArchDependentInteger

class documentation

class ArchDependentInteger(Integer):

An integer type whose size depends on whether the current context is 32 or 64 bits.

Information

Parameters
signedness	an element of the `Signedness` enum indicating whether instances of this type are signed
endianness	an element of the `Endianness` enum indicating the endianness of instances of this type
size32	the size in a 32 bits context
size64	the size in a 64 bits context
Raises
`ValueError`	if one of the passed sizes is negative or null

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, depending on the current context.
Instance Variable	`size32`	Undocumented
Instance Variable	`size64`	Undocumented
Property	`endianness`	Property: The endianness of this integer type.
Property	`signedness`	Property: The signedness of this integer type.
Method	`_possible_sizes`	Undocumented
Instance Variable	`_endianness`	Undocumented
Instance Variable	`_signedness`	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.

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

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, depending on the current context.

Information

Parameters
context	The context object. See package documentation.
Returns
An `integer`.
Raises
`ValueError`	If called without a context.
