Detailed Description

Helper class associating a Varnode with the block where it is defined.

This class explicitly stores a Varnode with the index of the BlockBasic that defines it. If a Varnode does not have a defining PcodeOp it is assigned an index of 0. This facilitates quicker sorting of Varnodes based on their defining block.

Member Function Documentation

findFront()

int4 BlockVarnode::findFront ( int4  blocknum, const vector< BlockVarnode > &  list  )

static

Find the first Varnode defined in the BlockBasic of the given index.

A BlockVarnode is identified from a sorted list. The position of the first BlockVarnode in this list that has the given BlockBasic index is returned.

Parameters

blocknum	is the index of the BlockBasic to search for
list	is the sorted list of BlockVarnodes

Returns

the index of the BlockVarnode within the list or -1 if no Varnode in the block is found

set()

void BlockVarnode::set

(

Varnode *

v

)

Set this as representing the given Varnode.

This instance assumes the identity of the given Varnode and the defining index is cached to facilitate quick sorting.

Parameters

v	is the given Varnode
