Method Details

newMap

protected SlotMap<T> newMap(SlotMapOwner<T> owner,
 int expansion)

add

public void add(SlotMapOwner<T> owner,
 Slot<T> newSlot)

Description copied from interface: SlotMap

Insert a new slot to the map. Both "name" and "indexOrHash" must be populated. Note that ScriptableObject generally adds slots via the "modify" method.

Specified by:

add in interface SlotMap<T extends PropHolder<T>>

compute

public <S extends Slot<T>> S compute(SlotMapOwner<T> owner,
 CompoundOperationMap<T> mutableMap,
 Object key,
 int index,
 SlotMap.SlotComputer<S,T> compute)

Specified by:

compute in interface SlotMap<T extends PropHolder<T>>

isEmpty

public boolean isEmpty()

Description copied from interface: SlotMap

Return whether the map is empty.

Specified by:

isEmpty in interface SlotMap<T extends PropHolder<T>>

modify

public Slot<T> modify(SlotMapOwner<T> owner,
 Object key,
 int index,
 int attributes)

Description copied from interface: SlotMap

Return the Slot that matches EITHER "key" or "index". (It will use "key" if it is not null, and otherwise "index".) If no slot exists, then create a default slot class.

Specified by:

modify in interface SlotMap<T extends PropHolder<T>>

key - The key for the slot, which should be a String or a Symbol.

index - if key is zero, then this will be used as the key instead.

attributes - the attributes to be set on the slot if a new slot is created. Existing slots will not be modified.

Returns:

a Slot, which will be created anew if no such slot exists.

query

public Slot<T> query(Object key,
 int index)

Description copied from interface: SlotMap

Retrieve the slot at EITHER key or index, or return null if the slot cannot be found.

Specified by:

query in interface SlotMap<T extends PropHolder<T>>

Parameters:

key - The key for the slot, which should be a String or a Symbol.

index - if key is zero, then this will be used as the key instead.

Returns:

either the Slot that matched the key and index, or null

size

public int size()

Description copied from interface: SlotMap

Return the size of the map.

Specified by:

size in interface SlotMap<T extends PropHolder<T>>

iterator

public Iterator<Slot<T>> iterator()

Specified by:

iterator in interface Iterable<T extends PropHolder<T>>
