org.aspectj.org.eclipse.jdt.core.dom.ClassInstanceCreation
Class instance creation expression AST node type.
ClassInstanceCreation: [ Expression . ] new [ < Type { , Type } > ] Type ( [ Expression { , Expression } ] ) [ AnonymousClassDeclaration ]
Not all node arrangements 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.
QualifiedType
discusses typical representations of qualified type references.
