TypeDescriptor

MethodType |
A method type represents the arguments and return type accepted and
returned by a method handle, or the arguments and return type passed
and expected by a method handle caller.
|
|
An entity that has a method type descriptor
Method descriptors conforming to JVMS {@jvms 4.3.3} can be described

Public methods
changeParameterType
public abstract M changeParameterType (int index,
F paramType)
Return a method descriptor that is identical to this one,
except that a single parameter type has been changed to the specified type.
Parameters |
index |
int : the index of the parameter to change |
paramType |
F : a field descriptor describing the new parameter type |
Returns |
M |
the new method descriptor |
changeReturnType
public abstract M changeReturnType (F newReturn)
Return a method descriptor that is identical to this one, except that the return
type has been changed to the specified type
Parameters |
newReturn |
F : a field descriptor for the new return type |
Returns |
M |
the new method descriptor |
dropParameterTypes
public abstract M dropParameterTypes (int start,
int end)
Return a method descriptor that is identical to this one,
except that a range of parameter types have been removed.
Parameters |
start |
int : the index of the first parameter to remove |
end |
int : the index after the last parameter to remove |
Returns |
M |
the new method descriptor |
Throws |
IndexOutOfBoundsException |
if start is outside the half-open
range [0, parameterCount) , or end is outside the closed range
[0, parameterCount] , or if start > end |
insertParameterTypes
public abstract M insertParameterTypes (int pos,

to insert |
Returns |
