public class NewArray_c
A NewArray
represents a new array expression such as new
File[8][] { null }
. It consists of an element type (e.g.,
File
), a list of dimension expressions (e.g., 8), 0 or more
additional dimensions (e.g., 1 for []), and an array initializer. The
dimensions of the array initializer must equal the number of additional "[]"
dimensions.

The expected type is determined by the context in that the child occurs
(e.g., for x = e
, the expected type of e
is

The expected type should impose the least constraints on the child's
type that are allowed by the parent node.
