Specified by:

size in interface EntityList

Overrides:

size in class AbstractEntityListWrapper

Returns:

The number of entities.

getKeys

public PrimaryKey[] getKeys()

Description copied from interface: EntityList

Read in subclasses if this array can contain null values or not.

Specified by:

getKeys in interface EntityList

index - The index.

eager - true, if a page should be eagerly loaded, if the entity's state is hollow, false otherwise.

Returns:

The entity at the specified index potentially in unusable state, or null.

Throws:

PersistException

IndexOutOfBoundsException

getKey

public PrimaryKey getKey(int index)

Description copied from interface: EntityList

Returns the PrimaryKey at the specified position.

Specified by:

getKey in interface EntityList

Overrides:

getKey in class AbstractEntityListWrapper

indexOf
