public interface ASTAssignableExpr
extends ASTPrimaryExpression

An expression that may be assigned by an assignment expression, or incremented or decremented. In the JLS, the result of such expressions is a variable, while other expressions evaluate to a value. The distinction is equivalent to C-world lvalue, rvalue.

 AssignableExpr ::= VariableAccess
                  | FieldAccess
                  | ArrayAccess

Method Detail

getAccessType

default @NonNull ASTAssignableExpr.AccessType getAccessType()

Returns how this expression is accessed in the enclosing expression. If this expression occurs as the left-hand-side of an assignment, or as the target of an increment or decrement expression, this method returns ASTAssignableExpr.AccessType.WRITE. Otherwise the value is just read.
