```
public MethodInfo(String className,
                  String methodName,
                  int modifiers,
                  String typeDescriptor,
                  String[] parameterNames,
                  int[] parameterAccessFlags,
                  List<AnnotationInfo> methodAnnotationInfo,
                  AnnotationInfo[][] parameterAnnotationInfo)
```
- Method Detail
  - getModifiers
```
public String getModifiers()
```
    Get the method modifiers as a string, e.g. "public static final". For the modifier bits, call getAccessFlags().
  - isConstructor
```
public boolean isConstructor()
```
    Returns true if this method is a constructor. Constructors have the method name "<init>". This returns false for private static class initializer blocks, which are named "<clinit>".
  - getClassName
```
public String getClassName()
```
    Get the name of the class this method is part of.
  - getMethodName
```
public String getMethodName()
```
    Returns the name of the method. Note that constructors are named "<init>", and private static class initializer blocks are named "<clinit>".
  - getAccessFlags
```
public int getAccessFlags()
```
    Returns the access flags of the method.
  - getTypeDescriptor
```
public String getTypeDescriptor()
```
    Returns the internal type descriptor for the method, e.g. "Ljava/lang/String;V"
  - getReturnTypeStr
```
public String getReturnTypeStr()
```
    Returns the return type for the method in string representation, e.g. "char[]". If this is a constructor, the returned type will be "void".
  - getReturnType
```
public Class<?> getReturnType()
                       throws IllegalArgumentException
```
    Returns the return type for the method as a Class reference. If this is a constructor, the return type will be void.class. Note that this calls Class.forName() on the return type, which will cause the class to be loaded, and possibly initialized. If the class is initialized, this can trigger side effects.
    
    Throws:
    
    IllegalArgumentException - if the return type for the method could not be loaded.
  - getParameterTypeStrs
```
public String[] getParameterTypeStrs()
```
    Returns the parameter types for the method in string representation, e.g. ["int", "List", "com.abc.XYZ"]. If the method has no parameters, returns a zero-sized array.
  - getParameterTypes
```
public Class<?>[] getParameterTypes()
                             throws IllegalArgumentException
```
    Returns the parameter types for the method. If the method has no parameters, returns a zero-sized array.
    Note that this calls Class.forName() on the parameter types, which will cause the class to be loaded, and possibly initialized. If the class is initialized, this can trigger side effects.
    
    Throws:
    
    IllegalArgumentException - if the parameter types of the method could not be loaded.
  - isPublic
```
public boolean isPublic()
```
    Returns true if this method is public.
  - isPrivate
```
public boolean isPrivate()
```
    Returns true if this method is private.
  - isProtected
```
public boolean isProtected()
```
    Returns true if this method is protected.
  - isPackagePrivate
```
public boolean isPackagePrivate()
```
    Returns true if this method is package-private.
  - isStatic
```
public boolean isStatic()
```
    Returns true if this method is static.
  - isFinal
```
public boolean isFinal()
```
    Returns true if this method is final.
  - isSynchronized
```
public boolean isSynchronized()
```
    Returns true if this method is synchronized.
  - isBridge
```
public boolean isBridge()
```
    Returns true if this method is a bridge method.
  - isVarArgs

  - isNative
```
public boolean isNative()
```
    Returns true if this method is a native method.
  - getParameterNames
```
public String[] getParameterNames()
```
    Returns the method parameter names, if available (only available in classfiles compiled in JDK8 or above using the -parameters commandline switch), otherwise returns null. Note that parameters may be unnamed, in which case the corresponding parameter name will be null.
  - getParameterAccessFlags
```
public int[] getParameterAccessFlags()
```
    Returns the parameter access flags, if available (only available in classfiles compiled in JDK8 or above using the -parameters commandline switch), otherwise returns null. Flag bits:
    - 0x0010 (ACC_FINAL): Indicates that the formal parameter was declared final.
    - 0x1000 (ACC_SYNTHETIC): Indicates that the formal parameter was not explicitly or implicitly declared in source code, according to the specification of the language in which the source code was written (JLS §13.1). (The formal parameter is an implementation artifact of the compiler which produced this class file.)
    - 0x8000 (ACC_MANDATED): Indicates that the formal parameter was implicitly declared in source code, according to the specification of the language in which the source code was written (JLS §13.1). (The formal parameter is mandated by a language specification, so all compilers for the language must emit it.)
  - getParameterModifiers
```
public String[] getParameterModifiers()
```
    Returns the parameter modifiers as a string (e.g. ["final", ""], if available (only available in classfiles compiled in JDK8 or above using the -parameters commandline switch), otherwise returns null.
  - getParameterAnnotationNames
```
public String[][] getParameterAnnotationNames()
```
    Returns the unique annotation names for annotations on each method parameter, if any parameters have annotations, else returns null.
  - getParameterAnnotationTypes
```
public Class<?>[][] getParameterAnnotationTypes()
```
    Returns the unique annotation types for annotations on each method parameter, if any parameters have annotations, else returns null.
  - getParameterAnnotationInfo
```
public AnnotationInfo[][] getParameterAnnotationInfo()
```
    Returns the annotations on each method parameter (along with any annotation parameters, wrapped in AnnotationInfo objects) if any parameters have annotations, else returns null.
  - getAnnotationNames
```
public List<String> getAnnotationNames()
```
    Returns the names of annotations on the method, or the empty list if none.
  - getAnnotationTypes
```
public List<Class<?>> getAnnotationTypes()
                                  throws IllegalArgumentException
```
    Returns a list of Class references for the annotations on this method, or the empty list if none. Note that this calls Class.forName() on the annotation types, which will cause each annotation class to be loaded.
    
    Throws:
    
    IllegalArgumentException - if the annotation type could not be loaded.
  - getAnnotationInfo
```
public List<AnnotationInfo> getAnnotationInfo()
```
    Get a list of annotations on this method, along with any annotation parameter values, wrapped in AnnotationInfo objects, or the empty list if none.
  - equals

public boolean equals(Object obj)
```
    Test class name, method name and type descriptor for equals().
    
    Overrides:
    
    equals in class Object

```
public int hashCode()
```
    Use hash code of class name, method name and type descriptor.
    
    Overrides:
    
    hashCode in class Object

```
public int compareTo(MethodInfo other)
```
    Sort in order of class name, method name, then type descriptor.
    
    Specified by:
