All Implemented Interfaces:

public class SimpleRuleImpl
extends RuleImpl

The Rule class extends the xml schema definition for more interactive behaviour! This is necessary because of the limitations of the XML Schema Specifiation. The rule class is implementation of the ECA (Event - Condition - Action) paradigma known from active database theory. Rules can only be definied in the xui specification.A rule will allways triggered by an event. Following events are possible: saveDocument -> fired calling serialization() on the Document class initialisation -> fired on initial document load or if a new Element will be added to the Document propertyChange -> fired on valueChanges A rule gets evaluated after the occurance of an event. If all conditions (in this version the relation between conditions are always a boolean AND) are evaluated as true, all defined actions get performed.

Version:

1.60

Constructor Detail

SimpleRuleImpl

public SimpleRuleImpl(long type,
                      Type source)

A Rule needs sourceType to be checked against with and a type which specifies the event type. The event type is necessary for the EventMulticaster to know if a Rule has to be fired or not.

Parameters:

String - type type of event saveDocument -> fired calling serialization() on the Document class initialisation -> fired on initial document load or if a new Element will be added to the Document propertyChange -> fired on valueChanges

source - source base for the ECA behaviour

SimpleRuleImpl

public SimpleRuleImpl(long type,
                      Type source,
                      java.lang.String scope)

A Rule needs sourceType to be checked against with and a type which specifies the event type. The event type is necessary for the EventMulticaster to know if a Rule has to be fired or not.

Parameters:

type - type of event save -> fired calling serialization() on the Document class initialisation -> fired on initial document load or if a new Element will be added to the Document propertyChange -> fired on valueChanges

source - source base for the ECA behaviour

scope - defines the scope of this rule in case of an occured event

SimpleRuleImpl

public SimpleRuleImpl(long type,
                      Type source,
                      java.lang.String scope,
                      boolean doesConcernNoneSerializableSource)

A Rule needs sourceType to be checked against with and a type which specifies the event type. The event type is necessary for the EventMulticaster to know if a Rule has to be fired or not.

Parameters:

type - type of event save -> fired calling serialization() on the Document class initialisation -> fired on initial document load or if a new Element will be added to the Document propertyChange -> fired on valueChanges

source - source base for the ECA behaviour

scope - defines the scope of this rule in case of an occured event

doesConcernNoneSerializableSource - apply the rule if the source is not serializable

SimpleRuleImpl

public SimpleRuleImpl(long type,
                      Type source,
                      java.lang.String executionMode,
                      java.lang.String scope,
                      boolean doesConcernNoneSerializableSource,
                      boolean doesConcernOnlyVisible)

A Rule needs sourceType to be checked against with and a type which specifies the event type. The event type is necessary for the EventMulticaster to know if a Rule has to be fired or not.

Parameters:

type - type of event save -> fired calling serialization() on the Document class initialisation -> fired on initial document load or if a new Element will be added to the Document propertyChange -> fired on valueChanges

source - source base for the ECA behaviour

executionMode - place where the rule needs to be executed (client,server or both)

scope - defines the scope of this rule in case of an occured event

doesConcernNoneSerializableSource - apply the rule if the source is not serializable

event - TODO

doesConcern

public boolean doesConcern(Type sourceType)
