reven2.types._integer.BigEndian(Integer) class documentationreven2.types._integer
(View In Hierarchy)
An integer type that wraps an inner integer type and forces its endianness to big-endian.
| Method | __init__ | Undocumented |
| Method | size_bytes | The minimal number of bytes necessary to hold an instance of this integer type. |
| Method | endianness | Property: The endianness of this integer type. Will always be big-endian. |
| Method | signedness | Property: The signedness of this integer type. |
| Method | inner | Property: The inner integer type. |
| Method | is_context_sensitive | Whether the context argument needed by some methods actually has an effect. |
Inherited from Type (via Integer):
| Method | parse | Parses the value of an instance of this type from a raw buffer, possibly depending on the context. |
Inherited from Type (via Integer):
| Method | parse | Parses the value of an instance of this type from a raw buffer, possibly depending on the context. |
The minimal number of bytes necessary to hold an instance of this integer type.
| Parameters | context | The context object. See package documentation. |
| Returns | An integer. | |
Property: The endianness of this integer type. Will always be big-endian.
| Returns | An Endianness.Big instance. | |
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.
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
