public class ClassInstanceCreation extends Expression
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.

Modifier and Type | Method and Description |
---|---|
List |
arguments()
Returns the live ordered list of argument expressions in this class
instance creation expression.
|
AnonymousClassDeclaration |
getAnonymousClassDeclaration()
Returns the anonymous class declaration introduced by this
class instance creation expression, if it has one.
|
Expression |
getExpression()
Returns the expression of this class instance creation expression, or
null if there is none. |
Name |
getName()
Deprecated.
In the JLS3 API, this method is replaced by
getType() , which returns a Type instead of a
Name . |
Type |
getType()
Returns the type instantiated in this class instance creation
expression (added in JLS3 API).
|
boolean |
isResolvedTypeInferredFromExpectedType()
Returns
true if the resolved class type has been inferred
from the assignment context (JLS4 15.12.2.8), false otherwise. |
static List |
propertyDescriptors(int apiLevel)
Returns a list of structural property descriptors for this node type.
|
IMethodBinding |
resolveConstructorBinding()
Resolves and returns the binding for the constructor invoked by this
expression.
|
void |
setAnonymousClassDeclaration(AnonymousClassDeclaration decl)
Sets whether this class instance creation expression declares
an anonymous class (that is, has class body declarations).
|
void |
setExpression(Expression expression)
Sets or clears the expression of this class instance creation expression.
|
void |
setName(Name name)
Deprecated.
In the JLS3 API, this method is replaced by
setType(Type) , which expects a Type instead of
a Name . |
void |
setType(Type type)
Sets the type instantiated in this class instance creation
expression (added in JLS3 API).
|
List |
typeArguments()
Returns the live ordered list of type arguments of this class
instance creation (added in JLS3 API).
