java.lang.Objectorg.eclipse.jdt.core.dom.ASTNode
org.eclipse.jdt.core.dom.Expression
org.eclipse.jdt.core.dom.ClassInstanceCreation
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 Java 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:
QualifiedType(SimpleType(SimpleName("A")),SimpleName("B"))
SimpleType(QualifiedName(SimpleName("A"),SimpleName("B")))

Note: This API element is only needed for dealing with Java code that uses new language features of J2SE 1.5. It is included in anticipation of J2SE 1.5 support, which is planned for the next release of Eclipse after 3.0, and may change slightly before reaching its final form.
