Specifies how the assignment-handler-object should be constructed and
how the content of this element should be used as configuration
information for that assignment-handler-object.
|
|
{content}
|
optional
|
the
content of the assignment-element can be used as configuration
information for your AssignmentHandler implementations. This allows the
creation of reusable delegation classes. for more about delegation
configuration, see
Section 16.2.3, “Configuration of delegations”

- cfg : cfg is optional, the default value is 'hibernate.cfg.xml'. The hibernate configuration file that contains the jdbc connection properties to the database and the mapping files.
- properties : properties is optional and overwrites *all* hibernate properties as found in the hibernate.cfg.xml
- createschema : if set to true, the jbpm database schema is created before the processes get deployed.
<action class="org.test.MyAction">
<city>Atlanta</city>
<rounds>5</rounds>
</action>
- 1) the class name (required) : the fully qualified class name of the delegation class.
<action class="org.test.MyAction">
- 2) configuration type (optional) : specifies the way to instantiate and configure the delegation object. By default the default constructor is used and the configuration information is ignored.
- 3) configuration (optional) : the configuration of the delegation object in the format as required by the configuration type.
- String doesn't need converting, of course. But it is trimmed.
- primitive types such as int, long, float, double, ...
- and the basic wrapper classes for the primitive types.
- lists, sets and collections. In that case each element of the xml-content is consitered as an element of the collection and is parsed, recursively applying the conversions. If the type of the elements is different from java.lang.String this can be indicated by specifying a type attribute with the fully qualified type name. For example, following snippet will inject an ArrayList of Strings into field 'numbers':
· <numbers>
· <element>one</element>
· <element>two</element>
· <element>three</element>
</numbers>
如,指定元素的属性
· <numbers>
· <element type= "com.withub.cms.jbpm.assignmenthandler.WriteNewsAssignmentHandler">one</element>
· <element>two</element>
· <element>three</element>
</numbers>
<numbers>
<entry><key>one</key><value>1</value></entry>
<entry><key>two</key><value>2</value></entry>
<entry><key>three</key><value>3</value></entry>
</numbers>
- maps. In this case, each element of the field-element is expected to have one subelement key and one element value . The key and element are both parsed using the conversion rules recursively. Just the same as with collections, a conversion to java.lang.String is assumed if no type attribute is specified.
- org.dom4j.Element
- for any other type, the string constructor is used.
public class MyAction implements ActionHandler {
// access specifiers can be private, default, protected or public
private String city;
Integer rounds;
...
}

<action class="org.test.MyAction">
<city>Atlanta</city>
<rounds>5</rounds>
</action>

Blocking
铁板一块?
默认false。如果为true,那么任务完成之后,才能离开节点。False,允许用户通过signal继续执行和离开节点。
|
attribute
|
optional
|
{yes|no|true|false},
default is false. If blocking is set to true, the node cannot be left
when the task is not finished. If set to false (default) a signal on the
token is allowed to continue execution and leave the node. The default
is set to false, because blocking is normally forced by the user
interface.
|
Signalling
有信号功能
默认true,task能够通过end(transition)离开任务节点。
|
attribute
|
optional
|
{yes|no|true|false},
default is true. If signalling is set to false, this task will never
have the capability of trigering the continuation of the token.

Expression
表达式
由于历史原因,它不是一个jPDL版EL表达式。相反,它是jBPM的身份组建的一个分配表达式。注意:这个实现依赖于jbpm身份组件。如果你不使用jBPM的身份组件,那么就不能使用它!
|
attribute
|
optional
|
For historical reasons, this attribute expression does not
refer to
the jPDL expression
,
but instead, it is an assignment expression for the jBPM identity
component. For more information on how to write jBPM identity component
expressions, see
Section 11.11.2, “Assignment expressions”
. Note that this implementation has a dependency on the jbpm identity component.

actor-id
参与者id
这是一个beanshell表达式。属性或方法返回一个String
|
attribute
|
optional
|
An actorId. Can be used in conjunction with pooled-actors. The actor-id is resolved as
an expression
.
So you can refer to a fixed actorId like this actor-id="bobthebuilder".
Or you can refer to a property or method that returns a String like
this: actor-id="myVar.actorId", which will invoke the getActorId method
on the task instance variable "myVar".
|
pooled-actors
参与者池。也是beanshell表达式。属性或方法返回一个String[],集合,或者,分割的参与者池的列表
|
attribute
|
optional
|
A
comma separated list of actorIds. Can be used in conjunction with
actor-id. A fixed set of pooled actors can be specified like this:
pooled-actors="chicagobulls, pointersisters". The pooled-actors will be
resolved as
an expression
.
So you can also refer to a property or method that has to return, a
String[], a Collection or a comma separated list of pooled actors.
