Method Summary

void	addSlot(ISlot slot) Adds a slot
IChunk	addSourceChunk(IChunk sourceChunk) ensure that all chunks added are copies
int	bind(SlotBasedRequest request, java.util.Map<java.lang.String,java.lang.Object> bindings, boolean isIterative) Required to permit status buffers to participate in the variable binding process of production instantiation.
void	dispose() clean up resources, called by the module that created the buffer
IChunk	getBusyChunk()
IChunk	getEmptyChunk()
IChunk	getErrorChunk()
IChunk	getFreeChunk()
IChunk	getFullChunk()
IChunk	getRequestedChunk()
ISlot	getSlot(java.lang.String name) return the actual named slot.
java.util.Collection<? extends ISlot>	getSlots() return a duplicate copy of all the slots
java.util.Collection<ISlot>	getSlots(java.util.Collection<ISlot> slots)
IChunk	getUnrequestedChunk()
void	initialize() must be called after the model has started so that we can ensure that the status slot values are properly initialized
boolean	isBufferEmpty() this actually checks the contents of the buffer slot which might not be the best test in the case of buffers that share a common set of state slots (i.e.
boolean	isBufferFull()
boolean	isBufferRequested()
boolean	isBufferUnrequested()
boolean	isStateBusy()
boolean	isStateError()
boolean	isStateFree()
void	removeSlot(ISlot slot) remove a slot

AbstractActivationBuffer6

public AbstractActivationBuffer6(java.lang.String name,
                                 IModule module)

Method Detail

dispose

public void dispose()

Description copied from interface: IActivationBuffer

clean up resources, called by the module that created the buffer

Specified by:

dispose in interface IActivationBuffer

Overrides:

dispose in class AbstractActivationBuffer

addSlot

public void addSlot(ISlot slot)

Description copied from interface: ISlotContainer

Adds a slot

Specified by:

addSlot in interface ISlotContainer

Parameters:

slot - The feature to be added to the ISlot attribute

removeSlot

public void removeSlot(ISlot slot)

Description copied from interface: ISlotContainer

remove a slot

Specified by:

removeSlot in interface ISlotContainer

Parameters:

slot - Description of Parameter

getSlot

public ISlot getSlot(java.lang.String name)

Description copied from interface: IUniqueSlotContainer

return the actual named slot. this is the backing slot, changes to it are propogated throughout the model

Specified by:

getSlot in interface IUniqueSlotContainer

Returns:

getSlots

public java.util.Collection<? extends ISlot> getSlots()

Description copied from interface: ISlotContainer

return a duplicate copy of all the slots

Specified by:

getSlots in interface ISlotContainer

Returns:

The slots value

getSlots

public java.util.Collection<ISlot> getSlots(java.util.Collection<ISlot> slots)

Specified by:

getSlots in interface ISlotContainer

isStateFree

public boolean isStateFree()

Specified by:

isStateFree in interface IStatusBuffer

isStateBusy

public boolean isStateBusy()

Specified by:

isStateBusy in interface IStatusBuffer

isStateError

public boolean isStateError()

Specified by:

isStateError in interface IStatusBuffer

isBufferUnrequested

public boolean isBufferUnrequested()

Specified by:

isBufferUnrequested in interface IStatusBuffer

public boolean isBufferRequested()

Specified by:

isBufferRequested in interface IStatusBuffer

isBufferFull

public boolean isBufferFull()

Specified by:

isBufferFull in interface IStatusBuffer

isBufferEmpty

public boolean isBufferEmpty()

this actually checks the contents of the buffer slot which might not be the best test in the case of buffers that share a common set of state slots (i.e. visual and visual-location)

Specified by:

isBufferEmpty in interface IStatusBuffer

See Also:

IStatusBuffer.isBufferEmpty()

setStateChunk

public void setStateChunk(IChunk chunk)

Specified by:

setStateChunk in interface IStatusBuffer

getErrorChunk

public IChunk getErrorChunk()

getRequestedChunk

public IChunk getRequestedChunk()

getUnrequestedChunk

public IChunk getUnrequestedChunk()

initialize

public void initialize()

must be called after the model has started so that we can ensure that the status slot values are properly initialized

Specified by:

initialize in interface IInitializable

Overrides:

initialize in class AbstractActivationBuffer

addSourceChunk

public IChunk addSourceChunk(IChunk sourceChunk)

ensure that all chunks added are copies

Specified by:

addSourceChunk in interface IActivationBuffer

Overrides:

addSourceChunk in class AbstractActivationBuffer

Parameters:

sourceChunk - chunk to be added

Returns:

the actual chunk added (in case a copy was made)

See Also:

IActivationBuffer.addSourceChunk(org.jactr.core.chunk.IChunk)

bind

public int bind(SlotBasedRequest request,
                java.util.Map<java.lang.String,java.lang.Object> bindings,
                boolean isIterative)
         throws CannotMatchException

Description copied from interface: IStatusBuffer

Required to permit status buffers to participate in the variable binding process of production instantiation. Since we don't know a priori what the slots the status buffers will contain or their possible values, it is up to the status buffers to attempt to bind variable values

Specified by:

bind in interface IStatusBuffer

Returns:

Throws:

CannotMatchException
