MethodInfo

All Superinterfaces:

MemberInfo

All Known Subinterfaces:

ModifiableMethod

All Known Implementing Classes:

MethodGenerator, MethodInfoBase, MethodInfoReflectiveImpl
```
public interface MethodInfo
extends MemberInfo
```
An interface that provides information about methods. This can be used to describe both MethodGenerators that are used to generate code and pre-existing Java classes.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`java.util.List<Variable>`	`arguments()`	Return a list of arguments for this method.
`java.util.List<Type>`	`exceptions()`	Return a list of all Exception types that are declared as being throwable from this method.
`java.lang.reflect.Constructor`	`getConstructor()`	Return the Constructor that is represented by this MethodInfo, or null if no such Constructor instance exists (because this MethodInfo represents a Constructor being generated, rather than a Constructor in a Class that is loaded into the VM).
`java.lang.reflect.Method`	`getMethod()`	Return the Method that is represented by this MethodInfo, or null if no such Method instance exists (because this MethodInfo represents a Method being generated, rather than a Method in a Class that is loaded into the VM).
`boolean`	`isConstructor()`	Returns true if this is a constructor, false if method.
`Type`	`returnType()`	Return the Type that is returned by this method.
`Signature`	`signature()`	Return the signature of this method.

- Method Detail
  - isConstructor
```
boolean isConstructor()
```
    Returns true if this is a constructor, false if method.
  - returnType
```
Type returnType()
```
    Return the Type that is returned by this method.
  - exceptions
```
java.util.List<Type> exceptions()
```
    Return a list of all Exception types that are declared as being throwable from this method.
  - arguments
```
java.util.List<Variable> arguments()
```
    Return a list of arguments for this method.
  - signature
```
Signature signature()
```
    Return the signature of this method.
  - getMethod
```
java.lang.reflect.Method getMethod()
```
    Return the Method that is represented by this MethodInfo, or null if no such Method instance exists (because this MethodInfo represents a Method being generated, rather than a Method in a Class that is loaded into the VM).
    
    Throws:
    
    java.lang.IllegalStateException - if isConstructor() is true.
  - getConstructor
```
java.lang.reflect.Constructor getConstructor()
```
    Return the Constructor that is represented by this MethodInfo, or null if no such Constructor instance exists (because this MethodInfo represents a Constructor being generated, rather than a Constructor in a Class that is loaded into the VM).
    
    Throws:
    
    java.lang.IllegalStateException - if isConstructor() is false.
