What is considered hearsay evidence in the context of ineffective assistance of counsel claims?

" 'Hearsay evidence' is evidence of a statement that was made other than by a witness while testifying at the hearing and that is offered to prove the truth of the matter stated." (Evid. Code, 1200.) In assessing an ineffective assistance of counsel claim, "the question is not what the 'best lawyers would have done,' nor 'even what most good lawyers would have done,' but simply whether 'some reasonable lawyer' could have acted, in the circumstances, as defense counsel acted in the case at bar." (People v. Jones, supra, 186 Cal.App.4th at p. 235.)
