Class AddAction

java.lang.Object
  org.jactr.core.production.action.DefaultAction
      org.jactr.core.production.action.AddAction

All Implemented Interfaces:

IAction, IBufferAction, ISlotContainer

Direct Known Subclasses:

ProxyAction

public class AddAction
extends DefaultAction
implements IBufferAction, ISlotContainer

AddAction represents the consequence of adding a chunk to a buffer. It can add an existing chunk to a buffer, add a chunk that is referenced by a variable name, or to create a new chunk in the buffer.

Constructor Detail

AddAction

public AddAction()

default constructor equivalent to AddAction("goal", null)

Since:

AddAction

public AddAction(java.lang.String bufferName,
                 java.lang.Object ref,
                 java.util.Collection<? extends ISlot> slots)

add a chunk (ref) to bufferName buffer

Parameters:

bufferName - name of the buffer to insert into

ref - IChunk, IChunkType, chunkName, or variable name

Since:

AddAction

public AddAction(java.lang.String bufferName,
                 java.lang.Object ref)

Method Detail

toString

public java.lang.String toString()

Description of the Method

Overrides:

toString in class java.lang.Object

Returns:

Description of the Returned Value

Since:

dispose

public void dispose()

Description of the Method

Specified by:

dispose in interface IAction

Overrides:

dispose in class DefaultAction

Since:

getReferant

public java.lang.Object getReferant()

Gets the referant attribute of the AddAction object

Returns:

The referant value

Since:

setReferant

public void setReferant(java.lang.Object o)

Sets the referant attribute of the AddAction object

Parameters:

o - The new referant value

Since:

bind

public IAction bind(java.util.Map<java.lang.String,java.lang.Object> bindings)
             throws CannotInstantiateException

Description copied from interface: IAction

Bind is called during the creation of an instantiation of a produciton. By the time this gets called, we know that all the conditions are matched and all the variables have been assigned. This method merely creates a copy of this action and applies those bindings. the IAction returned by this method will be the actual one that is fired. Normally, an action should not change the contents of variableBindings

Specified by:

bind in interface IAction

Returns:

Throws:

CannotInstantiateException

getBufferName

public java.lang.String getBufferName()

return the name of the buffer that the chunk will be added to

Specified by:

getBufferName in interface IBufferAction

Returns:

The bufferName value

Since:

setBufferName

public void setBufferName(java.lang.String name)

override the constructor and set the buffer name

Specified by:

setBufferName in interface IBufferAction

Parameters:

name - The new bufferName value

Since:

setChunkType

public void setChunkType(IChunkType ct)

set the chunktype of the chunk to be created

Parameters:

ct - The new chunkType value

Since:

setChunkName

public void setChunkName(java.lang.String name)

set the variable name of the chunk to be added. This must be a valid variable name and must be previously defined by a condition or another action

Parameters:

name - The new chunkName value

Since:

setChunk

public void setChunk(IChunk c)

set the chunk that will be added to the buffer

Parameters:

c - The new chunk value

Since:

getChunkName

public java.lang.String getChunkName()

return the variable name of the chunk if it has been specified, null otherwise

Returns:

The chunkName value

Since:

getChunkType

public IChunkType getChunkType()

return the chunktype of the to-be created chunk if it has been specified, null otherwise

Returns:

The chunkType value

Since:

getChunk

public IChunk getChunk()

return the chunk to be added if it was specified.

Returns:

The chunk value

Since:

getSlots

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

Return all the slots that this addaction will attempt to set for the to be added chunk.

Specified by:

getSlots in interface ISlotContainer

Returns:

The slots value

Since:

getSlots

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

Specified by:

getSlots in interface ISlotContainer

addSlot

public void addSlot(ISlot s)

In addition to adding chunks to a buffer, the IChunk?s slot values can be changed at the same time. This prevents the need to an additional action just to change the slot values. The slot added will be used to modify the same named slot in the chunk.

Specified by:

addSlot in interface ISlotContainer

Parameters:

s - The feature to be added to the ISlot attribute

Since:

removeSlot

public void removeSlot(ISlot s)

Remove a specific slot from the addaction.

Specified by:

removeSlot in interface ISlotContainer

Parameters:

s - Description of Parameter

Since:

fire

public double fire(IInstantiation instantiation,
                   double firingTime)

Description copied from class: DefaultAction

Description of the Method

Specified by:

fire in interface IAction

Specified by:

fire in class DefaultAction

Parameters:

instantiation - Description of the Parameter

firingTime - when this production was fired

Returns:

Description of the Return Value
