methodsDeclaredIn
Get all methods in a class hierarchy of the supplied classes. Both declared an non-declared (no duplicates).- Parameters:
cls
- The class whose methods to get.additionalClasses
- Additional classes whose methods to get.- Returns:
- All methods declared in this class hierarchy.
-
method
Get a method when it cannot be determined by methodName or parameter types only.The method will first try to look for a declared method in the same class. If the method is not declared in this class it will look for the method in the super class. This will continue throughout the whole class hierarchy. If the method is not found an
IllegalArgumentException
is thrown.- Parameters:
declaringClass
- The declaringClass of the class where the method is located.methodName
- The method names.parameterTypes
- All parameter types of the method (may benull
).- Returns:
- A
java.lang.reflect.Method
. - Throws:
MethodNotFoundException
- If a method cannot be found in the hierarchy.
-
method
Get a method without having to specify the method name.The method will first try to look for a declared method in the same class. If the method is not declared in this class it will look for the method in the super class. This will continue throughout the whole class hierarchy. If the method is not found an
IllegalArgumentException
is thrown. Since the method name is not specified anIllegalArgumentException
is thrown if two or more methods matches the same parameter types in the same class.- Parameters:
declaringClass
- The declaringClass of the class where the method is located.parameterTypes
- All parameter types of the method (may benull
).- Returns:
- A
java.lang.reflect.Method
. - Throws:
MethodNotFoundException
- If a method cannot be found in the hierarchy.TooManyMethodsFoundException
- If several methods were found.
-
methods
Get an array ofMethod
's that matches the supplied list of method names. Both instance and static methods are taken into account.- Parameters:
clazz
- The class that should contain the methods.methodName
- The name of the first method.additionalMethodNames
- Additional names of the methods that will be returned.- Returns:
- An array of Method's. May be of length 0 but not
null
. - Throws:
MethodNotFoundException
- If no method was found.
-
methods
Get an array ofField
's.- Parameters:
method
- The first field.additionalMethods
- Additional fields- Returns:
- An array of
Field
.
-
methods
Get an array ofMethod
's that matches the supplied list of method names. Both instance and static methods are taken into account.- Parameters:
clazz

- An array of Method's. May be of length 0 but not
null
. - Throws:
MethodNotFoundException
- If no method was found.
-
field
Get a field from a class.The method will first try to look for a declared field in the same class. If the method is not declared in this class it will look for the field in the super class. This will continue throughout the whole class hierarchy. If the field is not found an
IllegalArgumentException
is thrown.- Parameters:
declaringClass
- The declaringClass of the class where the method is located.fieldName
- The method names.- Returns:
- A
java.lang.reflect.Field
. - Throws:
FieldNotFoundException
- If a field cannot be found in the hierarchy.
-
fields
Get an array ofField

- An array of Field's. May be of length 0 but not
null
-
fields
