class BitmapInval(builtins.Exception)¶

Exception for an invalid bit number

class ByteHex(builtins.int)¶

Byte integer object which is displayed in hex

Methods defined here:
---------------------

__repr__ = __str__(self)

__str__(self)
Return str(self).

class DateStr(builtins.float)¶

Floating point object which is displayed as a date

Methods defined here:
---------------------

__str__(self)
Return str(self).

class Enum(builtins.int)¶

Enum base object
This should only be used as a base class where the class attributes
should be initialized

Methods defined here:
---------------------

__repr__(self)
Official string representation, display value using the mapping
dictionary provided as a class attribute when ENUM_REPR is False

__str__(self)
Informal string representation, display value using the mapping
dictionary provided as a class attribute

Static methods defined here:
----------------------------

__new__(cls, unpack)
Constructor which checks if integer is a valid enum value

class EnumInval(builtins.Exception)¶

Exception for an invalid enum value

class IntHex(builtins.int)¶

Integer object which is displayed in hex

Methods defined here:
---------------------

__repr__ = __str__(self)

__str__(self)
Return str(self).

class LongHex(builtins.int)¶

Long integer object which is displayed in hex

Methods defined here:
---------------------

__repr__ = __str__(self)

__str__(self)
Return str(self).

class OptionFlags(baseobj.BaseObj)¶

OptionFlags base object
This base class is used to have a set of raw flags represented by an
integer and splits every bit into an object attribute according to the
class attribute _bitnames where the key is the bit number and the value
is the attribute name.
This should only be used as a base class where the class attribute
_bitnames should be initialized. The class attribute _reversed can
also be initialized to reverse the _bitnames so the first bit becomes
the last, e.g., _reversed = 31, bits are reversed on a 32 bit integer
so 0 becomes 31, 1 becomes 30, etc.
Usage:


    from packet.utils import OptionFlags


    class MyFlags(OptionFlags):


        _bitnames = {0:"bit0", 1:"bit1", 2:"bit2", 3:"bit3"}


    x = MyFlags(10) # 10 = 0b1010


    The attributes of object are:


        x.rawflags = 10, # Original raw flags


        x.bit0     = 0,


        x.bit1     = 1,


        x.bit2     = 0,


        x.bit3     = 1,

Methods defined here:
---------------------

__init__(self, options)
Initialize object's private data.

str_flags(self)
Display the flag names which are set, e.g., in the above example
the output will be "bit1,bit3" (bit1=1, bit3=1)
Use "__str__ = OptionFlags.str_flags" to have it as the default
string representation

class RDMAbase(baseobj.BaseObj)¶

RDMA base object
Base class for an RDMA reduced payload object having RDMA write
chunks. An application having a DDP (direct data placement) item
must inherit this class and use the rdma_opaque method as a
dissecting function.
Usage:


    from packet.utils import RDMAbase


    # For an original class definition with DDP items


    class APPobj(BaseObj):


        def __init__(self, unpack):


            self.test = nfs_bool(unpack)


            self.data = unpack.unpack_opaque()


    # Class definition to access RDMA chunk writes


    class APPobj(RDMAbase):


        def __init__(self, unpack):


            self.test = self.rdma_opaque(nfs_bool, unpack)


            self.data = self.rdma_opaque(unpack.unpack_opaque)

Methods defined here:
---------------------

rdma_opaque(self, func, *kwts, **kwds)


    Dissecting method for a DDP item


    The first positional argument is the original dissecting


    function to be called when there is no RDMA write chunks.


    The rest of the arguments (positional or named) are passed


    directly to the dissecting function.
Data and other attributes defined here:
rdma_write_chunks = []

class RPCload(baseobj.BaseObj)¶

RPC load base object
This is used as a base class for an RPC payload object

Methods defined here:
---------------------

__str__(self)
Informal string representation

main_op(self)
Get the main NFS operation

rpc_str(self, name=None)
Display RPC string

Methods defined here:
---------------------

__repr__ = __str__(self)

__str__(self)
Return str(self).

class StrHex(builtins.bytes)¶

String object which is displayed in hex

Methods defined here:
---------------------

__str__(self)
Return str(self).
