Class CapabilityDispatcher

java.lang.Object

net.minecraftforge.common.capabilities.CapabilityDispatcher

All Implemented Interfaces:

ICapabilityProvider, INBTSerializable<NBTTagCompound>

public final class CapabilityDispatcher
extends java.lang.Object
implements INBTSerializable<NBTTagCompound>, ICapabilityProvider

A high-speed implementation of a capability delegator. This is used to wrap the results of the AttachCapabilitiesEvent. It is HIGHLY recommended that you DO NOT use this approach unless you MUST delegate to multiple providers instead just implement y our handlers using normal if statements. Internally the handlers are baked into arrays for fast iteration. The ResourceLocations will be used for the NBT Key when serializing.

Method Detail

hasCapability

public boolean hasCapability(Capability<?> capability,
                             @Nullable
                             EnumFacing facing)

Description copied from interface: ICapabilityProvider

Determines if this object has support for the capability in question on the specific side. The return value of this MIGHT change during runtime if this object gains or looses support for a capability. Example: A Pipe getting a cover placed on one side causing it loose the Inventory attachment function for that side. This is a light weight version of getCapability, intended for metadata uses.

Specified by:

hasCapability in interface ICapabilityProvider

Parameters:

capability - The capability to check

facing - The Side to check from: CAN BE NULL. Null is defined to represent 'internal' or 'self'

Returns:

True if this object supports the capability.

getCapability

public <T> T getCapability(Capability<T> capability,
                           @Nullable
                           EnumFacing facing)

Description copied from interface: ICapabilityProvider

Retrieves the handler for the capability requested on the specific side. The return value CAN be null if the object does not support the capability. The return value CAN be the same for multiple faces.

Specified by:

getCapability in interface ICapabilityProvider

Parameters:

capability - The capability to check

facing - The Side to check from: CAN BE NULL. Null is defined to represent 'internal' or 'self'

Returns:

True if this object supports the capability.
