variableName - the name of the variable to set

variableValue - the value of the variable to set

Returns:

the builder

setVariables

public CaseExecutionCommandBuilder setVariables(Map<String,Object> variables)

Description copied from interface: CaseExecutionCommandBuilder

Pass a map of variables to the case execution. If the variables are not already existing, they will be created in the case instance (which is the root execution) otherwise the existing variable will be updated.

Parameters:

variables - the map of variables

Returns:

the builder

Description copied from interface: CaseExecutionCommandBuilder

Pass a local variable to the case execution (not considering parent scopes).

Invoking this method multiple times allows passing multiple variables.

Specified by:

setVariableLocal in interface CaseExecutionCommandBuilder

Parameters:

localVariableName - the name of the variable to set

localVariableValue - the value of the variable to set

Returns:

setVariablesLocal

public CaseExecutionCommandBuilder setVariablesLocal(Map<String,Object> variablesLocal)

Description copied from interface: CaseExecutionCommandBuilder

Pass a map of variables to the case execution (not considering parent scopes).

Invoking this method multiple times allows passing multiple variables.

Specified by:

setVariablesLocal in interface CaseExecutionCommandBuilder

Parameters:

variablesLocal - the map of variables

Returns:

the builder

removeVariable

public CaseExecutionCommandBuilder removeVariable(String variableName)

Description copied from interface: CaseExecutionCommandBuilder

Pass a variable name of a variable to be removed for a case execution.

Invoking this method multiple times allows passing multiple variable names.

Specified by:

removeVariable in interface CaseExecutionCommandBuilder

Parameters:

variableName - the name of a variable to remove

Returns:

the builder

removeVariables

public CaseExecutionCommandBuilder removeVariables(Collection<String> variableNames)

Description copied from interface: CaseExecutionCommandBuilder

Pass a collection of variable names of variables to be removed for a case execution.

Invoking this method multiple times allows passing multiple variable names.

Specified by:

removeVariables in interface CaseExecutionCommandBuilder

Parameters:

variableNames - a collection of names of variables to remove

Returns:

the builder

removeVariableLocal

public CaseExecutionCommandBuilder removeVariableLocal(String variableName)

Description copied from interface: CaseExecutionCommandBuilder

Pass a variable name of a local variable to be removed for a case execution (not considering parent scopes).

Invoking this method multiple times allows passing multiple variable names.

Specified by:

removeVariableLocal in interface CaseExecutionCommandBuilder

Parameters:

variableName - the name of a variable to remove

Returns:

the builder

removeVariablesLocal

public CaseExecutionCommandBuilder removeVariablesLocal(Collection<String> variableNames)

Description copied from interface: CaseExecutionCommandBuilder

Pass a collection of variable names of local variables to be removed for a case execution (not considering parent scopes).

execute

public void execute()

Description copied from interface: CaseExecutionCommandBuilder

Invoking this method will remove and/or set the passed variables.

This behaves as follows:

1. if at least one variable name of a variable to remove is passed, those variables will be removed.
2. if at least one local variable name of a local variable to remove is passed, those local variables will be removed.
3. if at least one variable to add or update is passed, those variables will be set for a case execution.
4. if at least one local variable to add or update is passed, those variables will be set for a case execution.

Specified by:

execute in interface CaseExecutionCommandBuilder

manualStart

public void manualStart()

Description copied from interface: CaseExecutionCommandBuilder

Additionally to CaseExecutionCommandBuilder.execute() the associated case execution will be started manually. Therefore there happens a transition from the state ENABLED to state ACTIVE.

According to CMMN 1.0 specification the state ACTIVE means, that the with the case execution related Stage or Task is executing in this state:

• Task: the task will be completed immediately
• HumanTask: a new user task will be instantiated
• ProcessTask: a new process instance will be instantiated
• CaseTask: a new case instance will be instantiated

Specified by:

manualStart in interface CaseExecutionCommandBuilder

disable

public void disable()

Description copied from interface: CaseExecutionCommandBuilder

Additionally to CaseExecutionCommandBuilder.execute() the associated case execution will be disabled. Therefore there happens a transition from the state ENABLED to state DISABLED.

According to CMMN 1.0 specification the state DISABLED means, that the with the case execution related Stage or Task should not be executed in the case instance.

If the given case execution has a parent case execution, that parent case execution will be notified that the given case execution has been disabled. This can lead to a completion of the parent case execution if the completion criteria are fulfilled.

Specified by:

disable in interface CaseExecutionCommandBuilder

reenable

public void reenable()

Description copied from interface: CaseExecutionCommandBuilder

Additionally to CaseExecutionCommandBuilder.execute() the associated case execution will be re-enabled. Therefore there happens a transition from the state DISABLED to state ENABLED.

According to CMMN 1.0 specification the state DISABLED means, that the with the case execution related Stage or Task is waiting for a decision to become ACTIVE or DISABLED once again.

Specified by:

reenable in interface CaseExecutionCommandBuilder

complete

public void complete()

Description copied from interface: CaseExecutionCommandBuilder

Additionally to CaseExecutionCommandBuilder.execute() the associated case execution will be completed. Therefore there happens a transition from the state ACTIVE to state COMPLETED.

It is only possible to complete a case execution which is associated with a Stage or Task.

In case of a Stage the completion can only be performed when the following criteria are fulfilled:

• there are no children in the state ACTIVE

For a Task instance, this means its purpose has been accomplished:

• HumanTask has been completed by human.

If the given case execution has a parent case execution, that parent case execution will be notified that the given case execution has been completed. This can lead to a completion of the parent case execution if the completion criteria are fulfilled.

Specified by:

complete in interface CaseExecutionCommandBuilder

close

public void close()

Description copied from interface: CaseExecutionCommandBuilder

Additionally to CaseExecutionCommandBuilder.execute() the associated case instance will be closed, so that no further work or modifications is allowed for the associated case instance. Therefore there happens a transition from the state COMPLETED to state CLOSED.

Specified by:

close in interface CaseExecutionCommandBuilder
