All Implemented Interfaces:

java.lang.Cloneable, java.io.Serializable

public class AssignmentStatement

extends Statement

AssignmentStatements can only assign values to variables, and not to array elements. AssignmentStatements are not expressions as they are in C or Java, and thus chaining is not allowed. i.e. a = b = c;
