Method Summary

void	assertFact(Fact f1)
void	createReader(java.lang.String logicalName, java.io.InputStream in) createReader method is used by the ReteEngine to open a read stream
void	createReader(java.lang.String logicalName, java.lang.String filename) createReader method is used by the ReteEngine to open a read stream
void	createWriter(java.lang.String logicalName, java.io.OutputStream os) createWriter method is used by the ReteEngine to open a write stream
void	createWriter(java.lang.String logicalName, java.lang.String filename, boolean append) createWriter method is used by the ReteEngine to open a write stream
protected void	executeAction(Action a, Info info) executeAction is what causes a rule action to be executed when a rule has been matched to.
private java.lang.String	getFactList(java.util.Vector input)
java.util.Hashtable	getReaders() return the tables where the readers are stored for the read and readln actions
java.util.Hashtable	getWriters() return the hashtable where the output writers are stored for the print and println actions
(package private) OntologyDb	ontology() superceeded by getOntologyDb()
void	reset()
void	retract(Fact f1)
void	run()
private boolean	sameInput(java.util.Vector store, java.util.Vector input) store and input contain an ordered list of (ground) facts The method getIdString() of the Fact class can be used to compare the lists
void	setReaders(java.util.Hashtable readers) set the hashtable of readers for the rete actions - it is unlikely that agent developers will need this method
void	setWriters(java.util.Hashtable writers) set the hashtable of writers for the rete actions - unlikely to be of much use to agent developers
java.lang.String	toString()
(package private) void	update(java.lang.String path, int tag, java.util.Vector input, Bindings bindings, ActionNode node)

Method Detail

getWriters

public java.util.Hashtable getWriters()

return the hashtable where the output writers are stored for the print and println actions

getReaders

public java.util.Hashtable getReaders()

return the tables where the readers are stored for the read and readln actions

setReaders

public void setReaders(java.util.Hashtable readers)

set the hashtable of readers for the rete actions - it is unlikely that agent developers will need this method

setWriters

public void setWriters(java.util.Hashtable writers)

set the hashtable of writers for the rete actions - unlikely to be of much use to agent developers

createWriter

public void createWriter(java.lang.String logicalName,
                         java.io.OutputStream os)

createWriter method is used by the ReteEngine to open a write stream

createWriter

public void createWriter(java.lang.String logicalName,
                         java.lang.String filename,
                         boolean append)

createWriter method is used by the ReteEngine to open a write stream

createReader

public void createReader(java.lang.String logicalName,
                         java.lang.String filename)

createReader method is used by the ReteEngine to open a read stream

createReader

public void createReader(java.lang.String logicalName,
                         java.io.InputStream in)

createReader method is used by the ReteEngine to open a read stream

ontology

OntologyDb ontology()

superceeded by getOntologyDb()

update

void update(java.lang.String path,
            int tag,
            java.util.Vector input,
            Bindings bindings,
            ActionNode node)

reset

public void reset()

assertFact

public void assertFact(Fact f1)

retract

public void retract(Fact f1)

run

public void run()

executeAction

protected void executeAction(Action a,
                             Info info)

executeAction is what causes a rule action to be executed when a rule has been matched to. This uses an AbstractFactory to get the action and then asks it to execute itself

getFactList

private java.lang.String getFactList(java.util.Vector input)

sameInput

private boolean sameInput(java.util.Vector store,
                          java.util.Vector input)

store and input contain an ordered list of (ground) facts The method getIdString() of the Fact class can be used to compare the lists

toString

public java.lang.String toString()
