public class ClassInstanceCreation
extends Expression

Class instance creation expression AST node type. For JLS2:

 ClassInstanceCreation:
        [ Expression . ] new Name
            ( [ Expression { , Expression } ] )
            [ AnonymousClassDeclaration ]
 
For JLS3, type arguments are added and the type name is generalized to a type so that parameterized types can be instantiated:
 ClassInstanceCreation:
        [ Expression . ]
            new [ < Type { , Type } > ]
            Type ( [ Expression { , Expression } ] )
            [ AnonymousClassDeclaration ]
 

Not all node arragements will represent legal JavaScript constructs. In particular, it is nonsense if the type is a primitive type or an array type (primitive types cannot be instantiated, and array creations must be represented with ArrayCreation nodes). The normal use is when the type is a simple, qualified, or parameterized type.

A type like "A.B" can be represented either of two ways:

  1. QualifiedType(SimpleType(SimpleName("A")),SimpleName("B"))
  2. SimpleType(QualifiedName(SimpleName("A"),SimpleName("B")))
The first form is preferred when "A" is known to be a type (as opposed to a package). However, a parser cannot always determine this. Clients should be prepared to handle either rather than make assumptions. (Note also that the first form became possible as of JLS3; only the second form existed in JLS2.)

Provisional API: This class/interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
