All Implemented Interfaces:

Iterable<T>

Direct Known Subclasses:

DefaultParameters

Modifier and Type	Method and Description
`protected abstract S`	`createFrom(List<T> parameters)`
`protected abstract T`	`createParameter(MethodParameter parameter)` Creates a `Parameter` instance for the given `MethodParameter`.
`T`	`getBindableParameter(int bindableIndex)` Returns a bindable parameter with the given index.
`S`	`getBindableParameters()` Returns a `Parameters` instance with effectively all special parameters removed.
`int`	`getNumberOfParameters()` Returns the number of parameters.
`int`	`getPageableIndex()` Returns the index of the `Pageable` `Method` parameter if available.
`T`	`getParameter(int index)` Returns the parameter with the given index.
`int`	`getSortIndex()` Returns the index of the `Sort` `Method` parameter if available.
`boolean`	`hasPageableParameter()` Returns whether the method the `Parameters` was created for contains a `Pageable` argument.
`boolean`	`hasParameterAt(int position)` Returns whether we have a parameter at the given position.
`boolean`	`hasSortParameter()` Returns whether the method the `Parameters` was created for contains a `Sort` argument.
`boolean`	`hasSpecialParameter()` Returns whether the method signature contains one of the special parameters (`Pageable`, `Sort`).
`static boolean`	`isBindable(Class<?> type)` Returns whether the given type is a bindable parameter.
`Iterator<T>`	`iterator()`
`boolean`	`potentiallySortsDynamically()` Returns whether we potentially find a `Sort` parameter in the parameters.

    Creates a new instance of Parameters.
    
    Parameters:
    method -
  - Parameters
```
protected Parameters(List<T> originals)
```
    Creates a new Parameters instance with the given Parameters put into new context.
    
    Parameters:

- Method Detail
  - createParameter
```
protected abstract T createParameter(MethodParameter parameter)
```
    Creates a Parameter instance for the given MethodParameter.
    
    Parameters:
    parameter - will never be null.
    
    Returns:
  - hasPageableParameter
```
public boolean hasPageableParameter()
```
    Returns whether the method the Parameters was created for contains a Pageable argument.
    
    Returns:
  - getPageableIndex
```
public int getPageableIndex()
```
    Returns the index of the Pageable Method parameter if available. Will return -1 if there is no Pageable argument in the Method's parameter list.
    
    Returns:
    the pageableIndex
  - getSortIndex
```
public int getSortIndex()
```
    Returns the index of the Sort Method parameter if available. Will return -1 if there is no Sort argument in the Method's parameter list.
    
    Returns:
  - hasSortParameter
```
public boolean hasSortParameter()
```
    Returns whether the method the Parameters was created for contains a Sort argument.
    
    Returns:
  - potentiallySortsDynamically
```
public boolean potentiallySortsDynamically()
```
    Returns whether we potentially find a Sort parameter in the parameters.
    
    Returns:
  - getParameter
```
public T getParameter(int index)
```
    Returns the parameter with the given index.
    
    Parameters:
    index -
    
    Returns:
  - hasParameterAt
```
public boolean hasParameterAt(int position)
```
    Returns whether we have a parameter at the given position.
    
    Parameters:
    position -
    
    Returns:
  - hasSpecialParameter
```
public boolean hasSpecialParameter()
```
    Returns whether the method signature contains one of the special parameters (Pageable, Sort).
    
    Returns:
  - getNumberOfParameters
```
public int getNumberOfParameters()
```
    Returns the number of parameters.
    
    Returns:
  - getBindableParameters
```
public S getBindableParameters()
```
    Returns a Parameters instance with effectively all special parameters removed.
    
    Returns:
    See Also:
    Parameter.TYPES, Parameter.isSpecialParameter()
  - createFrom
```
protected abstract S createFrom(List<T> parameters)
```
  - getBindableParameter
```
public T getBindableParameter(int bindableIndex)
```
    Returns a bindable parameter with the given index. So for a method with a signature of (Pageable pageable, String name) a call to #getBindableParameter(0) will return the String parameter.
    
    Parameters:
    bindableIndex -
    
    Returns:
  - isBindable
```
public static boolean isBindable(Class<?> type)
```
    Returns whether the given type is a bindable parameter.
    
    Parameters:
    type -
    
    Returns:
  - iterator
```
public Iterator<T> iterator()
```
    Specified by:
    
    iterator in interface Iterable<T extends Parameter>
