Connection between nondualism and idealism

[mochafrap]

Does nondualism necessarily leads to idealism? When answering, please define how you're using these terms if your definitions aren't what I list below - that way we'll be on the same page 

• Nondualism - all experience is one, and no experience can escape the large oneness of experience
• Idealism-  "the group of metaphysical philosophies that assert that reality, or reality as humans can know it, is fundamentally mental, mentally constructed, or otherwise immaterial" (taken from wikipedia)

PS: "Epistemologically, idealism manifests as a skepticism about the possibility of knowing any mind-independent thing." might or might not be important
