Constructor Detail

ParametersParameterAccessor

public ParametersParameterAccessor(Parameters<?,?> parameters,
                                   Object[] values)

Creates a new ParametersParameterAccessor.

Parameters:

parameters - must not be null.

values - must not be null.

Method Detail

getParameters

public Parameters<?,?> getParameters()

Returns the Parameters instance backing the accessor.

Returns:

the parameters will never be null.

getValues

protected Object[] getValues()

Returns the potentially unwrapped values.

Returns:

getPageable

public Pageable getPageable()

Description copied from interface: ParameterAccessor

Returns the Pageable of the parameters, if available. Returns null otherwise.

Specified by:

getPageable in interface ParameterAccessor

Returns:

getSort

public Sort getSort()

Description copied from interface: ParameterAccessor

Returns the sort instance to be used for query creation. Will use a Sort parameter if available or the Sort contained in a Pageable if available. Returns null if no Sort can be found.

Specified by:

getSort in interface ParameterAccessor

Returns:

getDynamicProjection

public Optional<Class<?>> getDynamicProjection()

Returns the dynamic projection type if available, null otherwise.

Specified by:

getDynamicProjection in interface ParameterAccessor

Returns:

findDynamicProjection

@Nullable
public Class<?> findDynamicProjection()

Returns the dynamic projection type if available, null otherwise.

Specified by:

findDynamicProjection in interface ParameterAccessor

Returns:

getValue

protected <T> T getValue(int index)

Returns the value with the given index.

Parameters:

index -

Returns:

getBindableValue

public Object getBindableValue(int index)

Description copied from interface: ParameterAccessor

Returns the bindable value with the given index. Bindable means, that Pageable and Sort values are skipped without noticed in the index. For a method signature taking String, Pageable , String, #getBindableParameter(1) would return the second String value.

Specified by:

getBindableValue in interface ParameterAccessor

Returns:

hasBindableNullValue

public boolean hasBindableNullValue()

Description copied from interface: ParameterAccessor

Returns whether one of the bindable parameter values is null.

Specified by:

hasBindableNullValue in interface ParameterAccessor

Returns:

iterator

public org.springframework.data.repository.query.ParametersParameterAccessor.BindableParameterIterator iterator()

Description copied from interface: ParameterAccessor

Returns an iterator over all bindable parameters. This means parameters implementing Pageable or Sort will not be included in this Iterator.

Specified by:

iterator in interface Iterable<Object>

Specified by:

iterator in interface ParameterAccessor
