Constructor Detail

• MethodDescriptor

  public MethodDescriptor(Method method)

  Create a MethodDescriptor based on a method object. The parameters types will be listed with their canonical name.

  Parameters:

  method - The method that is converted to a MethodDescriptor.

• MethodDescriptor

  public MethodDescriptor(String methodDescriptor)

  Creates a MethodDescriptor based on its String representation.

  Parameters:

  methodDescriptor - The string representation of the MethodDescriptor. See toString().

  Throws:

  NullPointerException - if the methodDescriptor parameter is null.

  IllegalArgumentException - if the provided String representation cannot be parsed.

• MethodDescriptor

  public MethodDescriptor(String name,
                          String[] parameterTypeNames)

  Creates a method descriptor based on the name of the method and the name of the type of the parameters.

  Parameters:

  name - The name of the method.

  parameterTypeNames - The name of parameter types or null if the parameters are not defined. In case the parameters are not defined, the locate(Class, boolean) method will return with the first found method that has the specified name. The type names can be specified in the form of Class.getCanonicalName() or Class.getSimpleName().

  Throws:

  NullPointerException - if the name parameter is null or any of the element of parameterTypeNames is null.

Method Detail

• equals

  public boolean equals(Object obj)

  Overrides:

  equals in class Object

• getMethodName

  public String getMethodName()

  Returns the name of the method.

  Returns:

  The name of the method.

• getParameterTypeNames

  public String[] getParameterTypeNames()

  Returns a clone of the parameter type array. Modification of the returned array will not cause the modification of the array that is stored by the MethodDescriptor instance.

  Returns:

  The clone of the parameterTypeNames array.

• hashCode

  public int hashCode()

  Overrides:

  hashCode in class Object

• locate

  public Method locate(Class clazz,
                       boolean privateMethodAccepted)

  Searching the method in the provided class and in super classes. For more information see matches(Method) and MethodUtil.locateMethodByPreference(Class, boolean, MethodDescriptor...).

  Parameters:

  clazz - The class where the search starts.

  privateMethodAccepted - Whether to search private methods in the class that is passed in the clazz parameter.

  Returns:

  The matched method or null if no such method could be found.

  Throws:

  NullPointerException - if the clazz parameter is null.

• matches

  public boolean matches(Method method)

  Matches the provided method with this MethodDescriptor. A method matches to this descriptor if the method name is the same and if the parameters of the method match the getParameterTypeNames() array. If getParameterTypeNames() returns null, the method will return true if the passed method has the same name as the one that is specified in this MethodDescriptor.

  Parameters:

  method - The method object.

  Returns:

  True if the specified method matches with this MethodDescriptor.

• toString

  public String toString()

  Returns the String representation of this MethodDescriptor. The string representation contains the name of the method and if available, the list of parameter types enclosed with brackets. The String that is generated by this method can be passed to the MethodDescriptor(String) constructor. Parameter type names are listed as they are stored in the MethodDescriptor, the type name might be a Class.getCanonicalName() or a Class.getSimpleName(). Examples: "myMethod", myMethod(java.lang.String), myMethod(String).

  Overrides:

  toString in class Object
