Method Detail

createCaseInstanceByKey

CaseInstance createCaseInstanceByKey(String caseDefinitionKey)

Creates a new CaseInstance of the latest version of the case definition with the given key. The new case instance will be in the ACTIVE state.

Parameters:

caseDefinitionKey - the key of the case definition to instantiate

Throws:

NotValidException - when the given case definition key is null.

NotFoundException - when no case definition is deployed with the given key.

ProcessEngineException - when an internal exception happens during the execution of the command

createCaseInstanceByKey

CaseInstance createCaseInstanceByKey(String caseDefinitionKey,

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:

caseDefinitionKey - the key of the case definition to instantiate

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

Throws:

NotValidException - when the given case definition key is null.

Throws:

NotValidException - when the given case execution id or variable name is null

NotFoundException - when no case execution is found for the given case execution id

setVariables

void setVariables(String caseExecutionId,
                Map<String,Object> variables)

Pass a map of variables to the case execution. If the variables do not already exist, they are created in the case instance (which is the root execution). Otherwise existing variables are updated.

Parameters:

caseExecutionId - the case execution to set the variables for

variables - the map of variables

setVariablesLocal

void setVariablesLocal(String caseExecutionId,
                     Map<String,Object> variables)

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

Parameters:

caseExecutionId - the case execution to set the variables for

variables - the map of variables

setVariable

void setVariable(String caseExecutionId,
               String variableName,
               Object variableValue)

Pass a variable to the case execution. If the variable does not already exist, it is created in the case instance (which is the root execution). Otherwise, the existing variable is updated.

Parameters:

caseExecutionId - the case execution to set the variable for

variableName - the name of the variable to set

variableValue - the value of the variable to set

Throws:

NotValidException - when the given variable name is null

setVariableLocal
