Constructor Detail

DecisionTask

public DecisionTask()

DecisionTask

public DecisionTask(com.google.gwt.core.client.JavaScriptObject jsObj)

DecisionTask

public DecisionTask(java.lang.String ID,
                    java.lang.String nextElement,
                    java.lang.String failureElement)

Method Detail

getOrCreateRef

public static DecisionTask getOrCreateRef(com.google.gwt.core.client.JavaScriptObject jsObj)

create

public com.google.gwt.core.client.JavaScriptObject create()

Overrides:

create in class ProcessElement

setCriteria

public DecisionTask setCriteria(Criteria criteria)
                         throws java.lang.IllegalStateException

Simple or AdvancedCriteria to be applied against the Process.state.

Data values in this criteria prefixed with "$" will be treated as dynamic expressions as detailed in TaskInputExpression. Specifically, this means that for simple criteria, any property value that is a String and is prefixed with "$" will be assumed to be an expression, and for AdvancedCriteria, the same treatment will be applied to Criterion.value.

Note that dynamic expressions starting with "$input" are not applicable for an DecisionTask but "$inputRecord" can be used for direct reference to Process.state.

This property supports DynamicCriteria - use Criterion.valuePath to refer to values in the Process.ruleScope.

Parameters:

criteria - New criteria value. Default value is null

Returns:

DecisionTask instance, for chaining setter calls

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getCriteria

public Criteria getCriteria()

Simple or AdvancedCriteria to be applied against the Process.state.

Data values in this criteria prefixed with "$" will be treated as dynamic expressions as detailed in TaskInputExpression. Specifically, this means that for simple criteria, any property value that is a String and is prefixed with "$" will be assumed to be an expression, and for AdvancedCriteria, the same treatment will be applied to Criterion.value.

Note that dynamic expressions starting with "$input" are not applicable for an DecisionTask but "$inputRecord" can be used for direct reference to Process.state.

This property supports DynamicCriteria - use Criterion.valuePath to refer to values in the Process.ruleScope.

Returns:

Current criteria value. Default value is null

setFailureElement

public DecisionTask setFailureElement(java.lang.String failureElement)
                               throws java.lang.IllegalStateException

ID of the next sequence or element to proceed to if the criteria do not match.

Parameters:

failureElement - New failureElement value. Default value is null

Returns:

DecisionTask instance, for chaining setter calls

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getFailureElement

public java.lang.String getFailureElement()

ID of the next sequence or element to proceed to if the criteria do not match.

Returns:

Current failureElement value. Default value is null

setNextElement

public DecisionTask setNextElement(java.lang.String nextElement)
                            throws java.lang.IllegalStateException

Next sequence or element to execute if the criteria match the process state.

nextElement does not need to be specified if this element is part of a sequence and has a next element in the sequence.

Note that if there is both a sequence and a normal element with the same name in the current Process, the sequence will be used.

Overrides:

setNextElement in class ProcessElement

Parameters:

nextElement - New nextElement value. Default value is null

Returns:

DecisionTask instance, for chaining setter calls

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getNextElement

public java.lang.String getNextElement()

Next sequence or element to execute if the criteria match the process state.

nextElement does not need to be specified if this element is part of a sequence and has a next element in the sequence.

Note that if there is both a sequence and a normal element with the same name in the current Process, the sequence will be used.

Overrides:

getNextElement in class ProcessElement

Returns:

Current nextElement value. Default value is null
