                                                 EntityInfo entityInfo,
                                                 java.lang.Class<C> entityClass)

getAll

public java.util.Collection<T> getAll()

Specified by:

getAll in interface ObjectCursor<T>

Returns:

a new mutable Collection containing all elements contained in this ObjectCursor. If the ObjectCursor is empty an empty Collection is returned.

getCurrent

public T getCurrent()

Specified by:

getCurrent in interface ObjectCursor<T>

Returns:

the element at the current position of the ObjectCursor.
If the Cursor is before the first element, the position is changed to the first position, if the Cursor is after the last element, the position is changed to the last elements position

getFirst

public T getFirst()

Specified by:

getFirst in interface ObjectCursor<T>

Returns:

the element at the first position of the ObjectCursor.
The Cursor is moved to the first position.

getLast

public T getLast()

Specified by:

getLast in interface ObjectCursor<T>

Returns:

the element at the last position of the ObjectCursor.
The Cursor is moved to the last position.

getNext

public T getNext()

Description copied from interface: ObjectCursor

Returns the element at the next position of the ObjectCursor.
The Cursor is moved to the next position.

Specified by:

getNext in interface ObjectCursor<T>

Returns:

Element at next position

See Also:

ObjectCursor.hasNext()

getNext

public java.util.Collection<T> getNext(int amount)

Specified by:

getNext in interface ObjectCursor<T>

Parameters:

amount - Number of positions to move forward

Returns:

a new mutable Collection containing the next amount elements contained in this ObjectCursor. If the ObjectCursor contains less than amount elements following the current position a collection with less than amount elements is returned.

getOne

public T getOne()

Specified by:

getOne in interface ObjectCursor<T>

Returns:

the element at the first position of the ObjectCursor. It is expected, that the Cursor contains exactly one element.

getPrevious

public T getPrevious()

Specified by:

getPrevious in interface ObjectCursor<T>

Returns:

the element at the position before the current position of the ObjectCursor.
The Cursor is moved to the previous position.

See Also:

ObjectCursor.hasPrevious()

getPrevious

public java.util.Collection<T> getPrevious(int amount)

Specified by:

getPrevious in interface ObjectCursor<T>

Parameters:

amount - Number of positions to move backwards

Returns:

a new mutable Collection containing the previous amount elements contained in this ObjectCursor. If the ObjectCursor contains less than amount elements preceding the current position a collection with less than amount elements is returned.

hasNext

public boolean hasNext()

Specified by:

hasNext in interface ObjectCursor<T>

Returns:

true if there is at least one more element after the current position, false otherwise.

See Also:

ObjectCursor.getNext()

hasPrevious

public boolean hasPrevious()

Specified by:

hasPrevious in interface ObjectCursor<T>

Returns:

true if there is at least one more element before the current position, false otherwise.

See Also:

iterator

public java.util.Iterator<T> iterator()

Specified by:

iterator in interface java.lang.Iterable<T>

Specified by:
