All Implemented Interfaces:

SaffronType

Enclosing class:

OJTypeFactoryImpl

private class OJTypeFactoryImpl.OJScalarType

extends SaffronTypeFactoryImpl.TypeImpl

Type based upon an OJClass.

Use this class only if the class is a 'pure' OJClass:

• If the OJClass is based upon a Java class, call SaffronTypeFactoryImpl.createJavaType(java.lang.Class) instead.
• If the OJClass is synthetic, call SaffronTypeFactoryImpl.createProjectType(net.sf.saffron.core.SaffronType[], java.lang.String[]) or SaffronTypeFactoryImpl.createJoinType(net.sf.saffron.core.SaffronType[]) instead.
