All is a condition that evaluates to true if all of its child conditions evaluate to true.

Any is a condition that evaluates to true if any of its enclosed conditions evaluate to true.

Bool accesses the value held by key and type asserts it to a pointer to a bool.

Diff accesses the value held by key and type asserts it to a set.

Float64 accesses the value held by key and type asserts it to a pointer to a float64.

HasChange is a condition that evaluates to true if the value accessed has changed.

Int accesses the value held by key and type asserts it to a pointer to a int.

IsNewResource is a condition that evaluates to true if the resource access is new.

JSON accesses the value held by key and unmarshals it into a map.

List accesses the value held by key and returns an iterator able to go over its elements.

Map accesses the value held by key and type asserts it to a map.

Not is a condition that evaluates to true if its child condition evaluates to false.

Set accesses the value held by key, type asserts it to a set and returns an iterator able to go over its elements.

Slice accesses the value held by key and type asserts it to a slice.

String accesses the value held by key and type asserts it to a pointer to a string.

Iterator is used to iterate over a list or set.

ResourceData generalises schema.ResourceData so that we can reuse the accessor methods defined below.

Condition is a function that checks whether a condition holds true for a value being accessed.

MapData wraps a map satisfying the Data interface, so it can be used in the accessor methods defined below.
