public String typeName()
This type name is always available even if the type has not yet been created or loaded.
public Type type()
throws ClassNotLoadedException
For example, if a target class defines:
short s;
Date d;
byte[] ba;
And the JDI client defines these Field objects:
Field sField = targetClass.fieldByName("s");
Field dField = targetClass.fieldByName("d");
Field baField = targetClass.fieldByName("ba");
to mirror the corresponding fields, then sField.type()
is a ShortType, dField.type() is the
ReferenceType for java.util.Date and
((ArrayType)(baField.type())).componentType() is a
ByteType.
Note: if the type of this field is a reference type (class,
interface, or array) and it has not been created or loaded
by the declaring type's class loader - that is,
declaringType().classLoader(),
then ClassNotLoadedException will be thrown.
Also, a reference type may have been loaded but not yet prepared,
in which case the type will be returned
but attempts to perform some operations on the returned type
(e.g. fields()) will throw
a ClassNotPreparedException.
Use ReferenceType.isPrepared() to determine if
a reference type is prepared.
