| Modifier and Type | Method | Description |
|---|---|---|
M |
changeParameterType |
Return a method descriptor that is identical to this one, except that a single parameter type has been changed to the specified type. |
M |
changeReturnType |
Return a method descriptor that is identical to this one, except that the return type has been changed to the specified type |
M |
dropParameterTypes |
Return a method descriptor that is identical to this one, except that a range of parameter types have been removed. |
M |
insertParameterTypes |
Return a method descriptor that is identical to this one, except that a range of additional parameter types have been inserted. |
F[] |
