create FilterPredicate from string

[Gil Vernik]

Hello,

Is there any easy way to create FilterPredicate from String?  For example, 
I have a string 
?and(or(eq(ic, 7), eq(ic, 17)), eq(bc, Binary{?aaa"}))? and I want to 
create FilterPredicate form it.

Of course I can parse it into expression tree and then create 
FilterPredicate, but I wonder if there is an easier solution or may be it 
already exists.

Thanks,
Gil.
