### Remarks

Use this method to access every node in the graph. Nodes are returned in the order they were created.

The list includes:

* Your own [Node](/engine/6000.7/script-reference/unity/graphtoolkit/editor/node.md)s

* [ContextNode](/engine/6000.7/script-reference/unity/graphtoolkit/editor/contextnode.md)s

* [IVariableNode](/engine/6000.7/script-reference/unity/graphtoolkit/editor/ivariablenode.md)s

* [IConstantNode](/engine/6000.7/script-reference/unity/graphtoolkit/editor/iconstantnode.md)s

* [ISubgraphNode](/engine/6000.7/script-reference/unity/graphtoolkit/editor/isubgraphnode.md)s

It excludes [BlockNode](/engine/6000.7/script-reference/unity/graphtoolkit/editor/blocknode.md)s, which are only accessible through their parent [ContextNode](/engine/6000.7/script-reference/unity/graphtoolkit/editor/contextnode.md).
