Method Summary

Modifier and Type	Method	Description
static <E extends Enum<E>> Enum.EnumDesc<E>	of(ClassDesc enumClass, String constantName)	Returns a nominal descriptor for the specified enum class and name
E	resolveConstantDesc(MethodHandles.Lookup lookup)	Resolves this descriptor reflectively, emulating the resolution behavior of JVMS 5.4.3 and the access control behavior of JVMS 5.4.4.

resolveConstantDesc

public E resolveConstantDesc(MethodHandles.Lookup lookup)
                      throws ReflectiveOperationException

Description copied from interface: ConstantDesc

Resolves this descriptor reflectively, emulating the resolution behavior of JVMS 5.4.3 and the access control behavior of JVMS 5.4.4. The resolution and access control context is provided by the MethodHandles.Lookup parameter. No caching of the resulting value is performed.

Specified by:

resolveConstantDesc in interface ConstantDesc

Overrides:

resolveConstantDesc in class DynamicConstantDesc<E extends Enum<E>>

Parameters:

lookup - The MethodHandles.Lookup to provide name resolution and access control context

Returns:

the resolved constant value

Throws:

ReflectiveOperationException - if a class, method, or field could not be reflectively resolved in the course of resolution

toString

public String toString()

Description copied from class: DynamicConstantDesc

Returns a compact textual description of this constant description, including the bootstrap method, the constant name and type, and the static bootstrap arguments.

Overrides:

toString in class DynamicConstantDesc<E extends Enum<E>>

Returns:

A compact textual description of this call site descriptor
