Modifier and Type	Interface	Description
static enum	IGridNodeListener.State	Gives a reason for why the active state of the node might have changed.

Method Summary

Modifier and Type	Method	Description
default void	onGridChanged(T nodeOwner, IGridNode node)	called when the grid for the node has changed, the general grid state should not be trusted at this point.
default void	onInWorldConnectionChanged(T nodeOwner, IGridNode node)	Called by the IGridNode when the visible connections for the node have changed, useful for cable.
default void	onOwnerChanged(T nodeOwner, IGridNode node)	Called by the IGridNode when the node's owner has changed.
void	onSaveChanges(T nodeOwner, IGridNode node)	Called by the IGridNode when it's persistent state has changed and the host needs to ensure it is saved.
default void	onStateChanged(T nodeOwner, IGridNode node, IGridNodeListener.State state)	Called when one of the node's state properties has changed.

Method Details

onSaveChanges

void onSaveChanges(T nodeOwner,
 IGridNode node)

Called by the IGridNode when it's persistent state has changed and the host needs to ensure it is saved. Can be implemented on block entities by delegating to BlockEntity.setChanged() for example.

onInWorldConnectionChanged

default void onInWorldConnectionChanged(T nodeOwner,
 IGridNode node)

Called by the IGridNode when the visible connections for the node have changed, useful for cable.

onOwnerChanged

default void onOwnerChanged(T nodeOwner,
 IGridNode node)

Called by the IGridNode when the node's owner has changed. The node's state needs to be saved.

onGridChanged

default void onGridChanged(T nodeOwner,
 IGridNode node)

called when the grid for the node has changed, the general grid state should not be trusted at this point.

onStateChanged

default void onStateChanged(T nodeOwner,
 IGridNode node,
 IGridNodeListener.State state)

Called when one of the node's state properties has changed. Any of those changes might have potentially changed the active-state as well.

Parameters:

state - Indicates the node property that might have changed.
