Method Detail

getCar

public SchemeObject getCar()

Description copied from class: SchemeObject

Dealing with the static type system of Java is not convenient when manipulating SchemeObjects because Scheme itself is denamically typed. To make manipulating Scheme objects and lists in particular more convenient we make all SchemeObjects provide a getCar() and getCdr() method. If the object is not a SchemePair then these methods should through a ClassCastException. As such, the following are equivalent:

 SchemeObject o = ...;

 System.out.println(o.getCar());
 

and

 SchemeObject o = ...;

 Scheme.out.println(((SchemePair)o).getCar());
 

Overrides:

getCar in class SchemeObject

Following copied from class: SchemeObject

Returns:

The car of the SchemePair.

Throws:

ClassCastException - if this object does not override this method.
