getAssignableTypes	back to summary
private static void getAssignableTypes(JClass t, Set<JClass> s) Returns the set of all classes/interfaces that a given type implements/extends, including itself. For example, if you pass java.io.FilterInputStream, then the returned set will contain java.lang.Object, java.lang.InputStream, and java.lang.FilterInputStream.

getCommonBaseType back to summary

public static JType getCommonBaseType(JCodeModel codeModel, Collection<? extends JType> types)

Computes the common base type of two types.

Parameters

types:Collection<? extends JType>: set of JType objects.

getCommonBaseType	back to summary
public static JType getCommonBaseType(JCodeModel codeModel, JType... t) Computes the common base type of types. Todo this is a very interesting problem. Since one type has possibly multiple base types, it's not an easy problem. The current implementation is very naive. To make the result deterministic across differente JVMs, we have to use a Set whose ordering is deterministic.

getType	back to summary
public static JType getType(JCodeModel codeModel, String typeName, ErrorReceiver errorHandler, Locator errorSource) Obtains a `JType` object for the string representation of a type.
