Method Details

constant

AnnotationConstantValueEntry constant()

Returns the constant pool entry backing this constant element.

API Note:: Different types of constant values may share the same type of entry because they have the same computational type. For example, AnnotationValue.OfInt and AnnotationValue.OfChar are both backed by IntegerEntry. Use resolvedValue() for a value of accurate type.
Returns:: the constant pool entry backing this constant element

resolvedValue

Constable resolvedValue()

Returns the resolved live constant value, as an object. The type of the returned value may be a wrapper class or String.

API Note:: The returned object, despite being Constable, may not describe the right constant for encoding the annotation value in a class file. For example, Character returned by AnnotationValue.OfChar describes itself as a DynamicConstantPoolEntry, but it is actually backed by IntegerEntry in annotation format. Use constant() for a correct constant pool representation.
Returns:: the resolved live constant value, as an object
