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
).
