Method Detail

addHandlerField

public void addHandlerField(com.squareup.javapoet.TypeSpec.Builder classBuilder)

Description copied from interface: GeneratorStrategy

Adds a handler field to the class, if the activity is handled by a handler - e.g.:

 private UserTaskHandler approveUserTask;
 

Otherwise no field is added.

Specified by:

addHandlerField in interface GeneratorStrategy

Overrides:

addHandlerField in class DefaultStrategy

Parameters:

classBuilder - The class builder to use.

addHandlerMethod

public void addHandlerMethod(com.squareup.javapoet.TypeSpec.Builder classBuilder)

Description copied from interface: GeneratorStrategy

Adds a "handle" method to the class, if the activity is handled by a handler - e.g.:

 public UserTaskHandler handleApproveUserTask() {
   return approveUserTask;
 }
 

Otherwise no field is added.

Specified by:

addHandlerMethod in interface GeneratorStrategy

Overrides:

addHandlerMethod in class DefaultStrategy

Parameters:

classBuilder - The class builder to use.

buildHandlerMethodJavadoc

protected com.squareup.javapoet.CodeBlock buildHandlerMethodJavadoc()

applyHandler

public void applyHandler(com.squareup.javapoet.MethodSpec.Builder methodBuilder)

Description copied from interface: GeneratorStrategy

Adds code to the execute/apply method, if the activity is handled by a handler and a wait state - e.g.:

 assertThat(pi).isWaitingAt("placeOrderExternalTask");
 instance.apply(placeOrderExternalTask)
 

or the previous activity is an event based gateway.

Specified by:

applyHandler in interface GeneratorStrategy

Overrides:

applyHandler in class DefaultStrategy

Parameters:

methodBuilder - The method builder to use.

getHandler

public com.squareup.javapoet.CodeBlock getHandler()

Description copied from interface: GeneratorStrategy

Returns code for getting a handler field reference. Normally a handler field is references using TestCaseActivity.getLiteral(), but in case of a multi instance scope a specific getHandler method must be called.

Normally:

 approveUserTask
 

Multi instance scope:

 getApproveUserTaskHandler(loopIndex)
 

Specified by:

getHandler in interface GeneratorStrategy

Overrides:

getHandler in class DefaultStrategy

Returns:

The handler reference code.

initHandler

public void initHandler(com.squareup.javapoet.MethodSpec.Builder methodBuilder)

Description copied from interface: GeneratorStrategy

Adds code, which initializes a handler field.

 approveUserTask = new UserTaskHandler(getProcessEngine(), "approveUserTask");
 

Specified by:

initHandler in interface GeneratorStrategy

Overrides:

initHandler in class DefaultStrategy

Parameters:

methodBuilder - The method builder to use.

GeneratorStrategy.initHandlerStatement()

initHandlerStatement

public com.squareup.javapoet.CodeBlock initHandlerStatement()

Description copied from interface: GeneratorStrategy

Returns the statement that initializes the handler.

 new UserTaskHandler(getProcessEngine(), "approveUserTask");
 

Specified by:

initHandlerStatement in interface GeneratorStrategy

Overrides:

initHandlerStatement in class DefaultStrategy

Returns:

The code.
