Package sulley :: Module blocks :: Class size

[show private | hide private]

Class size

This block type is kind of special in that it is a hybrid between a block and a primitive (it can be fuzzed). The user does not need to be wary of this fact.

Method Summary
	`__init__(self, block_name, request, length, endian, format, inclusive, signed, math, fuzzable, name)` Create a sizer block bound to the block with the specified name.
Boolean	`mutate(self)` Wrap the mutation routine of the internal bit_field primitive.
Integer	`num_mutations(self)` Wrap the num_mutations routine of the internal bit_field primitive.
	`render(self)` Render the sizer.
	`reset(self)` Wrap the reset routine of the internal bit_field primitive.

Method Details

init(self, block_name, request, length=4, endian='<', format='binary', inclusive=False, signed=False, math=None, fuzzable=False, name=None)
(Constructor)

Create a sizer block bound to the block with the specified name. You *can not* create a sizer for any currently open blocks.

Parameters:: block_name - Name of block to apply sizer to
(type=String); request - Request this block belongs to
(type=s_request); length - (Optional, def=4) Length of sizer
(type=Integer); endian - (Optional, def=LITTLE_ENDIAN) Endianess of the bit field (LITTLE_ENDIAN: <, BIG_ENDIAN: >)
(type=Character); format - (Optional, def=binary) Output format, "binary" or "ascii"
(type=String); inclusive - (Optional, def=False) Should the sizer count its own length?
(type=Boolean); signed - (Optional, def=False) Make size signed vs. unsigned (applicable only with format="ascii")
(type=Boolean); math - (Optional, def=None) Apply the mathematical operations defined in this function to the size
(type=Function); fuzzable - (Optional, def=False) Enable/disable fuzzing of this sizer
(type=Boolean); name - Name of this sizer field
(type=String)

mutate(self)

Wrap the mutation routine of the internal bit_field primitive.

Returns:: True on success, False otherwise.
(type=Boolean)

num_mutations(self)

Wrap the num_mutations routine of the internal bit_field primitive.

Returns:: Number of mutated forms this primitive can take.
(type=Integer)

render(self)

Render the sizer.

reset(self)

Wrap the reset routine of the internal bit_field primitive.
