| 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
Summary
| Public methods |
| abstract M |
Return a method descriptor that is identical to this one, except that a single parameter type has been changed to the specified type.
|
| abstract M |
Return a method descriptor that is identical to this one, except that the return type has been changed to the specified type
|

Return a method descriptor that is identical to this one, except that a range of parameter types have been removed.
|
| abstract M |
Return a method descriptor that is identical to this one, except that a range of additional parameter types have been inserted.
|
| abstract Array<F>! |
Return an array of field descriptors for the parameter types of the method type described by this descriptor
|
| abstract Int |
Return the number of parameters in the method type
|
| abstract MutableList<F>! |
Return an immutable list of field descriptors for the parameter types of the method type described by this descriptor
|
| abstract F |

From class TypeDescriptor
String! |
descriptorString()
Returns the descriptor string for this TypeDescriptor object. If this TypeDescriptor object can be described in nominal form, then this method returns a type descriptor as specified in JVMS {@jvms 4.3}. The result descriptor string can be used to produce a java.lang.constant.ConstantDesc nominal descriptor. Otherwise, the result string is not a type descriptor. No java.lang.constant.ConstantDesc nominal descriptor can be produced from the result string.
