public interface TypeComponent extends Mirror, Accessible
Field
and Method
. Type components of the same name declared in different classes (including those related by inheritance) have different TypeComponent objects. TypeComponents can be used alone to retrieve static information about their declaration, or can be used in conjunction with a ReferenceType
or ObjectReference
to access values or invoke, as applicable.Modifier and Type | Method | Description |

String name()
Note: for fields, this is the field name; for methods, this is the method name; for constructors, this is <init>; for static initializers, this is <clinit>.
String signature()
Field.typeName()
and Method.returnTypeName()
for ways to help get a more readable representation of the type.String genericSignature()
null
if there is no generic signature.ReferenceType declaringType()
ReferenceType
mirrors either a class or an interface in the target VM.ReferenceType
for the type that declared this type component.boolean isStatic()
true
if this type component was declared static; false otherwise.boolean isFinal()
true
if this type component was declared final; false otherwise.boolean isSynthetic()
Not all target VMs support this query. See VirtualMachine.canGetSyntheticAttribute()
to determine if the operation is supported.
true
if this type component is synthetic; false
otherwise.UnsupportedOperationException
- if the target VM cannot provide information on synthetic attributes.
