OfField
interface OfField<F : TypeDescriptor.OfField<F>!> : TypeDescriptor
Known Direct Subclasses
| Class |
Instances of the class represent classes and interfaces in a running Java application.
|
|
An entity that has a field type descriptor. Field descriptors conforming to JVMS {@jvms 4.3.2} can be described
Summary
| Public methods |
| abstract F |
Return a descriptor for the array type whose component type is described by this descriptor
|
| abstract F |
If this field descriptor describes an array type, return a descriptor for its component type, otherwise return null.
|
| abstract Boolean |
Does this field descriptor describe an array type?
|
| abstract Boolean |
Does this field descriptor describe a primitive type (including void.)
|
| Inherited functions |
From class TypeDescriptor
String! |
descriptorString()
Returns the descriptor string for this TypeDescriptor object. If this TypeDescriptor object can be described in nominal form, then this method returns a type descriptor as specified in JVMS {@jvms 4.3}. The result descriptor string can be used to produce a java.lang.constant.ConstantDesc nominal descriptor. Otherwise, the result string is not a type descriptor. No java.lang.constant.ConstantDesc nominal descriptor can be produced from the result string.
