15.12.3. Compile-Time Step 3: Is the Chosen Method Appropriate?
If there is a most specific method declaration for a method invocation, it is called the
compile-time declaration
for the method invocation.
If the method invocation has, before the left parenthesis, a
MethodName
of the form
Iden-
tifier
, and the compile-time declaration is an instance method, then:
• If the method invocation occurs in a static context (§
8.1.3
), then a compile-time er-
ror occurs.
The reason is that a method invocation of this form cannot be used to invoke
• Otherwise, let
C
be the innermost enclosing class of which the compile-time de-
claration is a member.
If the invocation is not directly enclosed by
C
or an inner class of
C
, then a
compile-time error occurs.
If the method invocation has, before the left parenthesis, a
MethodName
of the form
TypeName
.
Identifier
, or if the method invocation, before the left parenthesis, has the form
TypeName
.
NonWildTypeArguments Identifier
, then the compile-time declaration must be
static
, or a compile-time error occurs.
The reason is that a method invocation of this form does not specify a reference to an
object that can serve as this within the instance method.
If the method invocation has, before the left parenthesis, the form
super .
NonWildTypeAr-
guments
opt
Identifier
, then:
• If the compile-time declaration is
abstract
, a compile-time error occurs.
• If the method invocation occurs in a static context, a compile-time error occurs.
If the method invocation has, before the left parenthesis, the form
ClassName
. super .
NonWildTypeArguments
opt
Identifier
, then:
• If the compile-time declaration is
abstract
, a compile-time error occurs.
• If the method invocation occurs in a static context, a compile-time error occurs.
• Otherwise, let
C
be the class denoted by
ClassName
.
If the invocation is not directly enclosed by
C
or an inner class of
C
, then a
compile-time error occurs.
