Method Detail

businessKey

CaseInstanceBuilder businessKey(String businessKey)

A business key can be provided to associate the case instance with a certain identifier that has a clear business meaning. This business key can then be used to easily look up that case instance, see CaseInstanceQuery.caseInstanceBusinessKey(String). Providing such a business key is definitely a best practice.

Note that a business key MUST be unique for the given case definition WHEN you have added a database constraint for it. In this case, only case instance from different case definition are allowed to have the same business key and the combination of caseDefinitionKey-businessKey must be unique.

Parameters:

businessKey - a key that uniquely identifies the case instance in the context of the given case definition.

Returns:

the builder

setVariable

CaseInstanceBuilder setVariable(String variableName,
                              Object variableValue)

Pass a variable to the case instance.

Invoking this method multiple times allows passing multiple variables.

Parameters:

variableName - the name of the variable to set

variableValue - the value of the variable to set

Returns:

the builder

Throws:

NotValidException - when the given variable name is null

setVariables

CaseInstanceBuilder setVariables(Map<String,Object> variables)

Pass a map of variables to the case instance.

Invoking this method multiple times allows passing multiple variables.

Parameters:

variables - the map of variables

Returns:

the builder

create

CaseInstance create()

Creates a new CaseInstance, which will be in the ACTIVE state.

Throws:
