class ArchDependentInteger(Integer):

View In Hierarchy

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

Information

Parameters
signednessan element of the Signedness enum indicating whether instances of this type are signed
endiannessan element of the Endianness enum indicating the endianness of instances of this type
size32the size in a 32 bits context
size64the size in a 64 bits context
Raises
ValueErrorif 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.
def __init__(self, signedness, endianness, size32, size64):

Undocumented

def __str__(self):

Returns the nicely printable string representation of this instance.

Returns
strUndocumented
def is_context_sensitive(self):

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):

The minimal number of bytes necessary to hold an instance of this integer type, depending on the current context.

Information

Parameters
contextThe context object. See package documentation.
Returns
An integer.
Raises
ValueErrorIf called without a context.
