Class Location<E extends Extent>

java.lang.Object

org.spongepowered.api.world.Location<E>

Type Parameters:

E - The type of extent containing this location

All Implemented Interfaces:

DataHolder, DataSerializable, PropertyHolder, CompositeValueStore<DataHolder,DataManipulator<?,?>>, ValueContainer<DataHolder>

public final class Location<E extends Extent>
extends Object
implements DataHolder

A position within a particular Extent.

This class is primarily a helper class to represent a location in a particular Extent. The methods provided are proxy methods to ones on Extent.

Each instance can be used to either represent a block or a location on a continuous coordinate system. Internally, positions are stored using doubles. When a block-related method is used, the components of the position are each rounded to an integer.

Locations are immutable. Methods that change the properties of the location create a new instance.

Furthermore, this allows for the Entity to be customized further prior to traditional "ticking" and processing by core systems.

Parameters:

type - The type

Returns:

An entity, if one was created

Throws:

IllegalArgumentException - If the position or entity type is not valid to create

IllegalStateException - If a constructor cannot be found

See Also:

EntityUniverse.createEntity(EntityType, Vector3d)

spawnEntity

public boolean spawnEntity(Entity entity)

Spawns an Entity using the already set properties (extent, position, rotation) and applicable DataManipulators with the specified Cause for spawning the entity.

Note that for the Cause to be useful in the expected SpawnEntityEvent, a SpawnType should be provided in the EventContext for other plugins to understand and have finer control over the event.

The requirements involve that all necessary setup of states and data is already preformed on the entity retrieved from the various EntityUniverse.createEntity(EntityType,Vector3d) methods. Calling this will make the now-spawned entity able to be processed by various systems.

If the entity was unable to spawn, the entity is not removed, but it should be taken note that there can be many reasons for a failure.

Parameters:

entity - The entity to spawn

Returns:

True if successful, false if not

See Also:

EntityUniverse.spawnEntity(Entity)

spawnEntities

public Collection<Entity> spawnEntities(Iterable<? extends Entity> entities)

Similar to spawnEntity(Entity) except where multiple entities can be attempted to be spawned with a customary Cause. The recommended use is to easily process the entity spawns without interference with the cause tracking system.

Parameters:

entities - The entities which spawned correctly, or empty if none

Returns:

True if any of the entities were successfully spawned

See Also:

EntityUniverse.spawnEntities(Iterable)

asHighestLocation

Description copied from interface: PropertyHolder

Attempts to retrieve a specific Property type of this PropertyHolder. If the property is not applicable, Optional.empty() is returned.

properties can define various immutable information about a PropertyHolder that is dependent on the instance of the holder. As properties cannot be changed, the PropertyHolder can not change the information about its own properties either.

Specified by:

T - The type of property

Parameters:

propertyClass - The property class

Returns:

The property, if available

getApplicableProperties

public Collection<Property<?,?>> getApplicableProperties()

validateRawData

public boolean validateRawData(DataView container)

Description copied from interface: DataHolder

Validates the container with known data required to set the raw data to this DataHolder. If the container is incomplete or contains invalid data, false is returned.

This validation should be checked prior to calling DataHolder.setRawData(DataView) to avoid exceptions.

Specified by:

validateRawData in interface DataHolder

Parameters:

container - The raw data to validate

Returns:

True if the data is valid

setRawData

public void setRawData(DataView container)
                throws InvalidDataException

Description copied from interface: DataHolder

This setter is used to provide setting custom data that is not represented by the Data API, including forge mods and other unknown data. Attempts at validating known DataManipulators contained in the data container are made with the assumption that all necessary data exists.

Specified by:

setRawData in interface DataHolder

Parameters:

container - A container containing all raw data to set on this data holder

Throws:

InvalidDataException - If the container is missing or has invalid data that this holder will refuse

getContentVersion

public int getContentVersion()

Description copied from interface: DataSerializable

Gets the content version of this DataSerializable. The version may differ between instances of plugins and implementations such that the DataView from DataSerializable.toContainer() may include different information, or remove other information as they are no longer deemed necessary. The version goes hand in hand with DataContentUpdater as it is required when there exists any DataView of this DataSerializable with an "older" version.

Specified by:

getContentVersion in interface DataSerializable

Returns:

The version of the content being serialized

toContainer

public DataContainer toContainer()

Description copied from interface: DataSerializable

Serializes this object into a comprehensible DataContainer.

Specified by:

toContainer in interface DataSerializable

Returns:

A newly created DataContainer

get

public <T extends DataManipulator<?,?>> Optional<T> get(Class<T> containerClass)

Description copied from interface: CompositeValueStore

Gets the desired ValueContainer of type H if the ValueContainer is compatible. Since the return type is an Optional, a short way of checking compatibility and presence of the requested data is to mimic the following:

// MyCompositeValueStore extends CompositeValueStore<MyCompositeValueStore, DataManipulator<?>>
MyCompositeValueStore valueStore;
final Optional<DisplayNameData> displayOptional = valueStore.get(DisplayNameData.class);
if (displayOptional.isPresent()) {
// We know that we have a present DataManipulator and it's supported
System.out.println(displayOptional.get().displayName().get().toString());
}

This is the equivalent to performing the following:

MyCompositeValueStore valueStore;
if (valueStore.supports(DisplayNameData.class)) {
System.out.println(valueStore.getOrNull(DisplayNameData.class ).displayName().get().toString());
}

The advantage of this returning an Optional is that the ValueContainer may be unsupported, the required data missing and ignoring the possibility of nulls, it is a guarantee that if the Optional.isPresent() is true, the ValueContainer not only is supported, but there is already pre- existing data for the ValueContainer.

If it is necessary to ignore the Optional, Optional.orElse(Object) can be used to return a potentially null ValueContainer.

Specified by:

get in interface CompositeValueStore<DataHolder,DataManipulator<?,?>>

Type Parameters:

T - The type of ValueContainer

Parameters:

containerClass - The container class

Returns:

The value container, if available

get

public <T> Optional<T> get(Key<? extends BaseValue<T>> key)

Description copied from interface: ValueContainer

Attempts to get the underlying value backed by a BaseValue linked to the provided Key. If the Key is not supported, Optional.empty() is returned. It is important to check for support of a Key by either calling ValueContainer.supports(BaseValue) or ValueContainer.supports(Key).

Specified by:

get in interface ValueContainer<DataHolder>

Type Parameters:

T - The type of value

Parameters:

key - The key linking the

Returns:

The value, if available

getOrCreate

public <T extends DataManipulator<?,?>> Optional<T> getOrCreate(Class<T> containerClass)

Description copied from interface: CompositeValueStore

Gets the desired ValueContainer of type H if the ValueContainer is compatible. If insufficient data is available to provide a ValueContainer with all Values preset, a new instance of the ValueContainer is returned with "default" values. Since the return type is an Optional, a short way of checking compatibility and presence of the requested data is to mimic the following:

// MyCompositeValueStore extends CompositeValueStore<MyCompositeValueStore, DataManipulator<?>>
MyCompositeValueStore valueStore;
final Optional<DisplayNameData> displayOptional = valueStore.getOrCreate(DisplayNameData.class);
if (displayOptional.isPresent()) {
// We know that we have a present DataManipulator and it's supported
System.out.println(displayOptional.get().displayName().get().toString() );
}

This is the equivalent to performing the following:

MyCompositeValueStore valueStore;
if (valueStore.supports(DisplayNameData.class)) {
System.out.println(valueStore.get(DisplayNameData.class ).get().displayName().get().toString());
}

The advantage of this returning an Optional is that the ValueContainer may be unsupported, the required data missing and ignoring the possibility of nulls, it is a guarantee that if the Optional.isPresent() is true, the ValueContainer not only is supported, but some default values can be generated to create the desired ValueContainer.

If it is necessary to ignore the Optional, Optional.orElse(Object) can be used to return a potentially null ValueContainer.
