MethodConstant (Byte Buddy (without dependencies) 1.10.21 API)

java.lang.Object
- net.bytebuddy.implementation.bytecode.constant.MethodConstant

All Implemented Interfaces:

StackManipulation

Direct Known Subclasses:

MethodConstant.ForConstructor, MethodConstant.ForMethod
```
public abstract class MethodConstant
extends Object
implements StackManipulation
```
Represents the creation of a Method value which can be created from a given set of constant pool values and can therefore be considered a constant in the broader meaning.

Nested Class Summary

Nested Classes
Modifier and Type	Class and Description
`protected static class`	`MethodConstant.CachedConstructor` Represents a cached constructor for a `MethodConstant`.
`protected static class`	`MethodConstant.CachedMethod` Represents a cached method for a `MethodConstant`.
`static interface`	`MethodConstant.CanCache` Represents a `MethodConstant` that is directly loaded onto the operand stack without caching the value.
`protected static class`	`MethodConstant.CanCacheIllegal` Represents a method constant that cannot be represented by Java's reflection API.
`protected static class`	`MethodConstant.ForConstructor` Creates a `MethodConstant` for loading a `Constructor` instance onto the operand stack.
`protected static class`	`MethodConstant.ForMethod` Creates a `MethodConstant` for loading a `Method` instance onto the operand stack.
`protected static class`	`MethodConstant.PrivilegedLookup` Performs a privileged lookup of a method constant by using an `AccessController`.
