Uses of Interface
java.lang.constant.MethodTypeDesc
Package
Description
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.-
Uses of MethodTypeDesc in java.lang.constant
Modifier and TypeMethodDescriptionMethodTypeDesc.changeParameterType
(int index, ClassDesc paramType) Returns a MethodTypeDesc that is identical to this one, except that a single parameter type has been changed to the specified type.MethodTypeDesc.changeReturnType
(ClassDesc returnType) Returns a MethodTypeDesc that is identical to this one, except with the specified return type.MethodTypeDesc.dropParameterTypes
(int start, int end) Returns a MethodTypeDesc that is identical to this one, except that a range of parameter types have been removed.MethodTypeDesc.insertParameterTypes
(int pos, ClassDesc... paramTypes) Returns a MethodTypeDesc that is identical to this one, except that a range of additional parameter types have been inserted.DynamicCallSiteDesc.invocationType()
Returns aMethodTypeDesc
describing the invocation type that would appear in theNameAndType
operand of theinvokedynamic
.MethodHandleDesc.invocationType()
Returns aMethodTypeDesc
describing the invocation type of the method handle described by this nominal descriptor.static MethodTypeDesc
Returns a MethodTypeDesc given the return type and parameter types.static MethodTypeDesc
MethodTypeDesc.ofDescriptor
(String descriptor) Creates a MethodTypeDesc given a method descriptor string.Modifier and TypeMethodDescriptiondefault MethodHandleDesc
MethodHandleDesc.asType
(MethodTypeDesc type) Returns a MethodHandleDesc that describes this method handle adapted to a different type, as if byMethodHandle.asType(MethodType)
.static DynamicCallSiteDesc
DynamicCallSiteDesc.of
(DirectMethodHandleDesc bootstrapMethod, MethodTypeDesc invocationType) Creates a nominal descriptor for aninvokedynamic
call site whose bootstrap method has no static arguments and for which the name parameter isConstantDescs.DEFAULT_NAME
.static DynamicCallSiteDesc
DynamicCallSiteDesc.of
(DirectMethodHandleDesc bootstrapMethod, String invocationName, MethodTypeDesc invocationType) Creates a nominal descriptor for aninvokedynamic
call site whose bootstrap method has no static arguments.static DynamicCallSiteDesc
DynamicCallSiteDesc.of
(DirectMethodHandleDesc bootstrapMethod, String invocationName, MethodTypeDesc invocationType, ConstantDesc... bootstrapArgs) Creates a nominal descriptor for aninvokedynamic
call site.static DirectMethodHandleDesc
MethodHandleDesc.ofMethod
(DirectMethodHandleDesc.Kind kind, ClassDesc owner, String name, MethodTypeDesc lookupMethodType) Creates a MethodHandleDesc corresponding to an invocation of a declared method or constructor.DynamicCallSiteDesc.withNameAndType
(String invocationName, MethodTypeDesc invocationType) Returns a nominal descriptor for aninvokedynamic
call site whose bootstrap and bootstrap arguments are the same as this one, but with the specified invocationName and invocation invocationType -

Modifier and TypeMethodDescriptionMethodType.describeConstable()
Returns a nominal descriptor for this instance, if one can be constructed, or an emptyOptional
if one cannot be.
