Uses of Interface
java.lang.constant.ConstantDesc
Package
Description
Provides classes that are fundamental to the design of the Java
programming language.
Classes and interfaces to represent nominal descriptors for run-time
entities such as classes or method handles, and classfile entities such as
constant pool entries or
invokedynamic
call sites.The
java.lang.invoke
package provides low-level primitives for interacting
with the Java Virtual Machine.-

A nominal descriptor for a dynamic constant (one described in the constant pool withConstant_Dynamic_info
.)Modifier and TypeFieldDescriptionstatic final ConstantDesc
ConstantDescs.NULL
Nominal descriptor representing the constantnull
Modifier and TypeMethodDescriptionDynamicCallSiteDesc.bootstrapArgs()
ReturnsConstantDesc
s describing the bootstrap arguments for theinvokedynamic
.DynamicConstantDesc.bootstrapArgs()
Returns the bootstrap arguments for this constant.static <T> ConstantDesc
DynamicConstantDesc.ofCanonical
(DirectMethodHandleDesc bootstrapMethod, String constantName, ClassDesc constantType, ConstantDesc[] bootstrapArgs) Returns a nominal descriptor for a dynamic constant, transforming it into a more specific type if the constant bootstrap is a well-known one and a more specific nominal descriptor type (e.g., ClassDesc) is available.Modifier and TypeMethodDescriptionDynamicConstantDesc.bootstrapArgsList()
Returns the bootstrap arguments for this constant as an immutableList
.Optional<? extends ConstantDesc>
Constable.describeConstable()
Modifier and TypeMethodDescriptionstatic DynamicCallSiteDesc
DynamicCallSiteDesc.of
(DirectMethodHandleDesc bootstrapMethod, String invocationName, MethodTypeDesc invocationType, ConstantDesc... bootstrapArgs) Creates a nominal descriptor for aninvokedynamic
call site.static <T> DynamicConstantDesc<T>
DynamicConstantDesc.of
(DirectMethodHandleDesc bootstrapMethod, ConstantDesc... bootstrapArgs) Returns a nominal descriptor for a dynamic constant whose name parameter isConstantDescs.DEFAULT_NAME
, and whose type parameter is always the same as the bootstrap method return type.static <T> ConstantDesc
DynamicConstantDesc.ofCanonical
(DirectMethodHandleDesc bootstrapMethod, String constantName, ClassDesc constantType, ConstantDesc[] bootstrapArgs) Returns a nominal descriptor for a dynamic constant, transforming it into a more specific type if the constant bootstrap is a well-known one and a more specific nominal descriptor type (e.g., ClassDesc) is available.static <T> DynamicConstantDesc<T>
DynamicConstantDesc.ofNamed
(DirectMethodHandleDesc bootstrapMethod, String constantName, ClassDesc constantType, ConstantDesc... bootstrapArgs) Returns a nominal descriptor for a dynamic constant.DynamicCallSiteDesc.withArgs
(ConstantDesc... bootstrapArgs) Returns a nominal descriptor for aninvokedynamic
call site whose bootstrap method, name, and invocation type are the same as this one, but with the specified bootstrap arguments.ModifierConstructorDescriptionprotected
