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
(AST.parseCompilationUnit
may return either).FieldAccess
).

public int getNodeType()
ASTNode
For each concrete node type there is a unique node type constant (name
and value). The unique node type constant for a concrete node type such as
CastExpression
is ASTNode.CAST_EXPRESSION
.
