getClassByVMName

public JavaClass getClassByVMName(java.lang.String fqVMName)

Description copied from interface: JavaProvider

Fetch the JavaClass for the specified fully-qualified type name in VM notation. The type may denote an array type, a primitive type, or a class type.

If the qualified name specified represents an array type, the implementer should fetch the JavaClass for the underlying class first, then generate an array type for the class using getArrayType( class, dimensions ).

If the qualified name specifies a primitive type, the implementer is required to return the canonical PrimitiveType instance.

If the qualified name represents a class type, the implementation has the choice of fetching the class information from either a Java class (*.class) or source (*.java) file. The choice is given to implementations for performance reasons, though implementations are required to provide up-to-date information.

The '/' is a package delimiter, while the '$' can be treated literally as part of the class name, or as a class delimiter. Implementations must perform left-to-right resolution on the class name portion to determine whether '$' should be interpreted literally, or as a delimiter.

Although implementations are not required to return the same JavaClass instance each time, they are encouraged to do so as it will dramatically improve performance.

Specified by:

Parameters:

fqVMName - The fully qualified type name (different from the qualified source name and different from the descriptor) in VM notation. e.g. java/lang/Object, java/util/Map$Entry
