Type Parameters:

T - The type of the matched target.

All Known Implementing Classes:

MemberSubstitution.Substitution.Chain, MemberSubstitution.Substitution.ForFieldAccess, MemberSubstitution.Substitution.ForMethodInvocation, MemberSubstitution.Substitution.ForValue, MemberSubstitution.Substitution.Stubbing

Enclosing class:

MemberSubstitution
```
public static interface MemberSubstitution.Substitution<T extends MemberSubstitution.Target>
```
A substitution replaces or enhances an interaction with a field or method within an instrumented method.

Nested Class Summary

Nested Classes
Modifier and Type	Interface	Description
`static class`	`MemberSubstitution.Substitution.Chain<S extends MemberSubstitution.Target>`	A substitution chain allows for chaining multiple substitution steps for a byte code element being replaced.
`static interface`	`MemberSubstitution.Substitution.Factory<S extends MemberSubstitution.Target>`	A factory for creating a substitution for an instrumented method.
`static class`	`MemberSubstitution.Substitution.ForFieldAccess`	A substitution with a field access.
`static class`	`MemberSubstitution.Substitution.ForMethodInvocation`	A substitution with a method invocation.
`static class`	`MemberSubstitution.Substitution.ForValue`	A substitution that loads a fixed value.
`static class`	`MemberSubstitution.Substitution.Stubbing`	A substitution that drops any field or method access and returns the expected return type's default value, i.e `null` or zero for primitive types.

  - resolve
```
StackManipulation resolve(T target,
                          TypeList.Generic parameters,
                          TypeDescription.Generic result,
                          JavaConstant.MethodHandle methodHandle,
                          StackManipulation stackManipulation,
                          int freeOffset)
```
    Resolves this substitution into a stack manipulation.
    
    Parameters:
    
    target - The targeted member that is substituted.
    
    parameters - All parameters that serve as input to this access.
    
    result - The result that is expected from the interaction or void if no result is expected.
    
    methodHandle - A method handle describing the substituted expression.
    
    stackManipulation - The original byte code expression that is being executed.
    
    freeOffset - The first free offset of the local variable array that can be used for storing values.
    
    Returns:
    
    A stack manipulation that represents the access.
