Method Details

invokeFindAll

public Iterable<Object> invokeFindAll(Pageable pageable)

Description copied from interface: RepositoryInvoker

Invokes the find-all method of the underlying repository using the method taking a Pageable as parameter if available (i.e. the equivalent to PagingAndSortingRepository.findAll(Pageable)), using the method taking a Sort if available (i.e. the equivalent to PagingAndSortingRepository.findAll(Sort) by extracting the Sort contained in the given Pageable) or the plain equivalent to CrudRepository.findAll().

Specified by:

invokeFindAll in interface RepositoryInvoker

Parameters:

pageable - must not be null.

Returns:

the result of the invocation of the find-all method.

invokeFindAll

public Iterable<Object> invokeFindAll(Sort sort)

Description copied from interface: RepositoryInvoker

Invokes the find-all method of the underlying repository using the method taking a Sort as parameter if available (i.e. the equivalent to PagingAndSortingRepository.findAll(Sort)) or the plain equivalent to CrudRepository.findAll().

Specified by:

invokeFindAll in interface RepositoryInvoker

Parameters:

sort - must not be null.

Returns:

the result of the invocation of the find-all method.

hasDeleteMethod

public boolean hasDeleteMethod()

Description copied from interface: RepositoryInvocationInformation

Returns whether the repository has a method to delete objects.

Specified by:

hasDeleteMethod in interface RepositoryInvocationInformation

Returns:

hasFindAllMethod

public boolean hasFindAllMethod()

Description copied from interface: RepositoryInvocationInformation
