On scala 2.
On scala 2.9 with -Xexperimental enabled, produces a dynamically
typed view of this JValue which can be descended using dot-notation
for field names or apply-type syntax for arrays. It can be turned back
into a JValue with the static method. On scala 2.8, calling this is
not an error but using it to descend into fields is a compile-time error.
Note that certain field-names (the names common to all objects plus static,
apply, and applyDynamic cannot be accessed with simple field-notation.
Instead, pass them as strings to the apply method.
Forces this JValue to be fully evaluated.
Forces this JValue to be fully evaluated. In particular, the compound JsonCodecs will produce views of their inputs instead of fully-evaluated JValues. This can be problematic if the underlying structure can be mutated before this object is used, or if this object is passed to another thread.
What is or is not copied is not defined; the only postcondition is that there are no lazy values left in the returned tree.
An equal JValue with strict values.
Null.
