public class FieldAccess
Field access expression AST node type.
FieldAccess: Expression . Identifier
Note that there are several kinds of expressions that resemble field access expressions: qualified names, this expressions, and super field access expressions. The following guidelines help with correct usage:
ThisExpression
) containing a simple name.
"this" is a keyword, and therefore invalid as an identifier.FieldAccess
) containing a this expression
and a simple name. Again, this is because "this" is a keyword, and
therefore invalid as an identifier.SuperFieldAccess
). "super" is a also
keyword, and therefore invalid as an identifier.QualifiedName
) or as a field access
expression (FieldAccess
) containing simple names. Either
is acceptable, and there is no way to choose between them without
information about what the names resolve to
(ASTParser
may return either).FieldAccess
).

Provisional API: This class/interface is part of an interim API that is still under development and expected to
change significantly before reaching stability. It is being made available at this early stage to solicit feedback
from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken
(repeatedly) as the API evolves.
