Class AssignmentStatement

java.lang.Object
  org.teatrove.tea.parsetree.Node
      org.teatrove.tea.parsetree.Statement
          org.teatrove.tea.parsetree.AssignmentStatement

All Implemented Interfaces:

Serializable, Cloneable

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;
