public class FieldAccess
- extends
Expression
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:
- An expression like "foo.this" can only be represented as a this
expression (
ThisExpression) containing a simple name.
"this" is a keyword, and therefore invalid as an identifier.
- An expression like "this.foo" can only be represented as a field
access expression (
FieldAccess) containing a this expression
and a simple name. Again, this is because "this" is a keyword, and
therefore invalid as an identifier.
- An expression with "super" can only be represented as a super field
access expression (
SuperFieldAccess). "super" is a also
keyword, and therefore invalid as an identifier.
- An expression like "foo.bar" can be represented either as a
qualified name (
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).
- Other expressions ending in an identifier, such as "foo().bar" can
only be represented as field access expressions
(
FieldAccess).
