Specified by:

preMemoryAllocation in interface ReasoningMonitor

preFreeMemory

public void preFreeMemory(String message,
 long memoryInBytes)

Description copied from interface: ReasoningMonitor

called before freeing up "memoryInBytes" memory

preFreeMemory in interface ReasoningMonitor

preRuleEvaluation

public void preRuleEvaluation(Rule rule)

Description copied from interface: ReasoningMonitor

called before a rule is evaluated

Specified by:

preRuleEvaluation in interface ReasoningMonitor

Parameters:

rule - , the rule

postRuleEvaluation

public void postRuleEvaluation(Rule rule)

Description copied from interface: ReasoningMonitor

called after a rule has been evaluated

Specified by:

postRuleEvaluation in interface ReasoningMonitor

Parameters:

rule - , the rule

preJoin

public void preJoin(Rule rule,
 Literal literal,
 String operatorName,
 String receiverName,
 ReasoningRelation[] relationA,
 ReasoningRelation[] relationB,
 String msg)

Description copied from interface: ReasoningMonitor

Called before a join or negation is executed.
NOTE All relation arguments should be considered temporary.
This means the content of these relations will change during the
reasoning process and cannot be accessed after this method returns.

preJoin in interface ReasoningMonitor

Parameters:

rule - the rule

literal - the body literal

operatorName - the operator

receiverName - the next receiver

relationA - the left relation

relationB - the bottom relation

msg - an additional message (might be null)

postJoin

public void postJoin(Rule rule,
 Literal literal,
 String operatorName,
 String receiverName,

 String joinType,
 String msg)
              throws IOException,
EDBException

Description copied from interface: ReasoningMonitor

Called after a join or negation is executed.
NOTE All relation arguments should be considered temporary.
This means the content of these relations will change during the
reasoning process and cannot be accessed after this method returns.

Specified by:

postJoin in interface ReasoningMonitor

Parameters:

rule - the rule

literal - the body literal

operatorName - the operator

receiverName - the next receiver

relationA - the left relation
