String typeName()
This type name is always available even if the type has not yet been created or loaded.
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.
