Var.get_object_of_var()

Returns corresponding object of the variable.

The function returns the appropriate object for the Var, such as: LocalVariable, StateVariable, GlobalVariable, Argument.

It is essential to understand that Var represents not just a variable in general but a specific "placement" of that variable in the code while the classes like LocalVariable or StateVariable etc. represent the variable itself.

It is easy to see in an example:

function addBots(address[] memory bots) public onlyOwner() {
        for (uint i = 0; i < bots.length; i++) {
            if (bots[i] != uniswapV2Pair && bots[i] != address(uniswapV2Router)) {
                isBot[bots[i]] = true;
            }
        }
    }

Here the botsargument is used in different instructions, and each usage of the bots will be represented by a different Var, while the Argument object that can be retrieved using the get_object_of_var() function will represent the bots in general as an argument.

Example

from glider import *

def query():
	functions = Functions()\
		.with_one_property([MethodProp.HAS_STATE_VARIABLES_WRITTEN])\
		.exec(50,50)
	
	for function in functions:
		for instruction in function.instructions().exec():
			for operand in instruction.get_operands():
				vars = operand.get_local_vars()
				if len(vars)>0:
					for point in vars[0].forward_df():
						print("Var: "+vars[0].expression)
						local_var = vars[0].get_object_of_var()
						# lets use something specific to LocalVariable
						print(local_var.type)
						return [instruction]
	return []
