Method Detail

getNodeId

int getNodeId()

Get the nodeid.

Returns:

The nodeid.

getRelevantAttributes

AttributeSet getRelevantAttributes()

Get the set of relevant attribute types.

getIndirectAttributes

AttributeSet getIndirectAttributes()

Get the set of indirect attribute types. I.e. attributes of objects, which are not part of an object conditions (e.g. for chained extractors)

Returns:

The relevant attribute types.

createNodeMemory

java.lang.Object createNodeMemory(IOAVState state)

Create the node memory.

Parameters:

state - The state.

Returns:

The node memory.

getNodeMemory

java.util.Collection getNodeMemory(ReteMemory mem)

Get the memory for this node.

Returns:

The memory.

modifyIndirectObject

void modifyIndirectObject(java.lang.Object object,
                          OAVAttributeType type,
                          java.lang.Object oldvalue,
                          java.lang.Object newvalue,

                          ReteMemory mem,
                          AbstractAgenda agenda)

Propagate an indirect object change to this node.

Parameters:

object - The changed object.

clone

java.lang.Object clone()

Returns:

A clone of this object.

checkNodeConsistency

boolean checkNodeConsistency(ReteMemory mem)

Check the consistency of the node.
