processDefinitionName

ProcessInstanceQuery processDefinitionName(String processDefinitionName)

Select process instances whose process definition name is processDefinitionName

processDefinitionKey

ProcessInstanceQuery processDefinitionKey(String processDefinitionKey)

Select the process instances which are defined by a process definition with the given key.

processDefinitionId

ProcessInstanceQuery processDefinitionId(String processDefinitionId)

Select the process instances which are defined by a process definition with the given id.

superProcessInstanceId

ProcessInstanceQuery superProcessInstanceId(String superProcessInstanceId)

Select the process instances which are a sub process instance of the given super process instance.

subProcessInstanceId

ProcessInstanceQuery subProcessInstanceId(String subProcessInstanceId)

Select the process instance that have as sub process instance the given process instance. Note that there will always be maximum only one such process instance that can be the result of this query.

excludeSubprocesses

ProcessInstanceQuery excludeSubprocesses(boolean excludeSubprocesses)

Exclude sub processes from the query result;

involvedUser

ProcessInstanceQuery involvedUser(String userId)

Select the process instances with which the user with the given id is involved.

variableValueEquals

ProcessInstanceQuery variableValueEquals(String name,
                                       Object value)

Only select process instances which have a global variable with the given value. The type of variable is determined based on the value, using types configured in ProcessEngineConfiguration#getVariableTypes(). Byte-arrays and Serializable objects (which are not primitive type wrappers) are not supported.

Parameters:

name - name of the variable, cannot be null.

variableValueEquals

ProcessInstanceQuery variableValueEquals(Object value)

Only select process instances which have at least one global variable with the given value. The type of variable is determined based on the value, using types configured in ProcessEngineConfiguration#getVariableTypes(). Byte-arrays and Serializable objects (which are not primitive type wrappers) are not supported.

variableValueEqualsIgnoreCase

ProcessInstanceQuery variableValueEqualsIgnoreCase(String name,
                                                 String value)

Only select process instances which have a local string variable with the given value, case insensitive.

This method only works if your database has encoding/collation that supports case-sensitive queries. For example, use "collate UTF-8" on MySQL and for MSSQL, select one of the case-sensitive Collations available (MSDN Server Collation Reference).

Parameters:

name - name of the variable, cannot be null.

value - value of the variable, cannot be null.

variableValueNotEquals

ProcessInstanceQuery variableValueNotEquals(String name,
                                          Object value)

Only select process instances which have a global variable with the given name, but with a different value than the passed value. Byte-arrays and Serializable objects (which are not primitive type wrappers) are not supported.

Parameters:

name - name of the variable, cannot be null.

variableValueNotEqualsIgnoreCase

ProcessInstanceQuery variableValueNotEqualsIgnoreCase(String name,
                                                    String value)

Only select process instances which have a local string variable which is not the given value, case insensitive.

This method only works if your database has encoding/collation that supports case-sensitive queries. For example, use "collate UTF-8" on MySQL and for MSSQL, select one of the case-sensitive Collations available (MSDN Server Collation Reference).
