protected Parameter	createParameter(MethodParameter parameter)
Parameter	getBindableParameter(int bindableIndex) Returns a bindable parameter with the given index.
Parameters	getBindableParameters() Returns a Parameters instance with effectively all special parameters removed.

Parameter	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.

Method Detail

createParameter

protected Parameter createParameter(MethodParameter parameter)

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 Parameter 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 Parameters getBindableParameters()

Returns a Parameters instance with effectively all special parameters removed.

Returns:

Parameter.TYPES, Parameter.isSpecialParameter()

getBindableParameter

public Parameter 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<Parameter> iterator()

Specified by:

iterator in interface Iterable<Parameter>
