- Type Parameters:
R
- the return type of this visitor's methods. UseVoid
for visitors that do not need to return results.P
- the type of the additional parameter to this visitor's methods. UseVoid
for visitors that do not need an additional parameter.
- All Implemented Interfaces:
ElementVisitor<R,
P>
- Direct Known Subclasses:
ElementKindVisitor6
,SimpleElementVisitor7
RELEASE_6
source version.
Visit methods corresponding to RELEASE_6
language
constructs call defaultAction
, passing their
arguments to defaultAction
's corresponding parameters.
For constructs introduced in RELEASE_7
and later,
visitUnknown
is called instead.- API Note:
- Methods in this class may be overridden subject to their general
contract.
WARNING: The
ElementVisitor
interface implemented by this class may have methods added to it in the future to accommodate new, currently unknown, language structures added to future versions of the Java programming language. Therefore, methods whose names begin with"visit"
may be added to this class in the future; to avoid incompatibilities, classes and subclasses which extend this class should not declare any instance methods with names beginning with"visit"
.When such a new visit method is added, the default implementation in this class will be to directly or indirectly call the
visitUnknown
method. A new simple element visitor class will also be introduced to correspond to the new language level; this visitor will have different default behavior for the visit method in question. When a new visitor is introduced, portions of this visitor class may be deprecated, including its constructors. - Since:

Method Details
-
defaultAction
The default action for visit methods.- Implementation Requirements:
- The implementation in this class just returns
DEFAULT_VALUE
; subclasses will commonly override this method. - Parameters:
e
- the element to processp
- a visitor-specified parameter- Returns:
DEFAULT_VALUE
unless overridden
-
visitPackage
Visits a package element.- Implementation Requirements:
- This implementation calls
defaultAction
. - Parameters:
e
- the element to visitp
- a visitor-specified parameter- Returns:
- a visitor-specified result
-
visitType
Visits a type element.- Implementation Requirements:
- This implementation calls
defaultAction
. - Parameters:
e
- the element to visitp
- a visitor-specified parameter- Returns:
- a visitor-specified result
-
visitVariable
Visits a variable element.- Implementation Requirements:
- This implementation calls
defaultAction
, unless the element is aRESOURCE_VARIABLE
in which casevisitUnknown
is called. - Parameters:
e
- the element to visitp
- a visitor-specified parameter- Returns:
- a visitor-specified result
-
visitExecutable
Visits an executable element.- Implementation Requirements:
- This implementation calls
defaultAction
. - Parameters:
e
- the element to visitp
- a visitor-specified parameter- Returns:
- a visitor-specified result
-
visitTypeParameter
Visits a type parameter element.- Implementation Requirements:
- This implementation calls
defaultAction
. - Parameters:
e
- the element to visitp
- a visitor-specified parameter- Returns:
- a visitor-specified result
