Method Detail

variableId

VariableInstanceQuery variableId(String id)

Only select the variable with the given Id

Parameters:

the - id of the variable to select

Returns:

the query object

variableName

VariableInstanceQuery variableName(String variableName)

Only select variable instances which have the variable name.

variableNameIn

VariableInstanceQuery variableNameIn(String... variableNames)

Only select variable instances which have one of the variables names.

variableNameLike

VariableInstanceQuery variableNameLike(String variableNameLike)

Only select variable instances which have the name like the assigned variable name. The string can include the wildcard character '%' to express like-strategy: starts with (string%), ends with (%string) or contains (%string%).

executionIdIn

VariableInstanceQuery executionIdIn(String... executionIds)

Only select variable instances which have one of the executions ids.

processInstanceIdIn

VariableInstanceQuery processInstanceIdIn(String... processInstanceIds)

Only select variable instances which have one of the process instance ids.

caseExecutionIdIn

VariableInstanceQuery caseExecutionIdIn(String... caseExecutionIds)

Only select variable instances which have one of the case execution ids.

caseInstanceIdIn

VariableInstanceQuery caseInstanceIdIn(String... caseInstanceIds)

Only select variable instances which have one of the case instance ids.

taskIdIn

VariableInstanceQuery taskIdIn(String... taskIds)

Only select variable instances which have one of the task ids.

variableScopeIdIn

VariableInstanceQuery variableScopeIdIn(String... variableScopeIds)

Only select variables instances which have on of the variable scope ids.

activityInstanceIdIn

VariableInstanceQuery activityInstanceIdIn(String... activityInstanceIds)

Only select variable instances which have one of the activity instance ids.

variableValueEquals

VariableInstanceQuery variableValueEquals(String name,
                                        Object value)

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

Parameters:

name - name of the variable, cannot be null.

value - variable value, can be null.

variableValueNotEquals

VariableInstanceQuery variableValueNotEquals(String name,
                                           Object value)

Only select variable instances which have 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.

value - variable value, can be null.

variableValueGreaterThan

VariableInstanceQuery variableValueGreaterThan(String name,
                                             Object value)

Only select variable instances which value is greater than the passed value. Booleans, Byte-arrays and Serializable objects (which are not primitive type wrappers) are not supported.

Parameters:

name - variable name, cannot be null.

value - variable value, cannot be null.

variableValueGreaterThanOrEqual

VariableInstanceQuery variableValueGreaterThanOrEqual(String name,
                                                    Object value)

Only select variable instances which value is greater than or equal to the passed value. Booleans, Byte-arrays and Serializable objects (which are not primitive type wrappers) are not supported.

Parameters:

name - variable name, cannot be null.

value - variable value, cannot be null.

variableValueLessThan

VariableInstanceQuery variableValueLessThan(String name,
                                          Object value)

Only select variable instances which value is less than the passed value. Booleans, Byte-arrays and Serializable objects (which are not primitive type wrappers) are not supported.

Parameters:

name - variable name, cannot be null.

value - variable value, cannot be null.

variableValueLessThanOrEqual

VariableInstanceQuery variableValueLessThanOrEqual(String name,
                                                 Object value)

Only select variable instances which value is less than or equal to the passed value. Booleans, Byte-arrays and Serializable objects (which are not primitive type wrappers) are not supported.

Parameters:

name - variable name, cannot be null.

value - variable value, cannot be null.

disableBinaryFetching

VariableInstanceQuery disableBinaryFetching()

Disable fetching of byte array and file values. By default, the query will fetch such values. By calling this method you can prevent the values of (potentially large) blob data chunks to be fetched. The variables themselves are nonetheless included in the query result.

Returns:

the query builder

disableCustomObjectDeserialization

VariableInstanceQuery disableCustomObjectDeserialization()

Disable deserialization of variable values that are custom objects. By default, the query will attempt to deserialize the value of these variables. By calling this method you can prevent such attempts in environments where their classes are not available. Independent of this setting, variable serialized values are accessible.

variableValueLike

VariableInstanceQuery variableValueLike(String name,
                                      String value)

Only select variable instances which value is like the given value. This be used on string variables only.

Parameters:

name - variable name, cannot be null.

value - variable value, cannot be null. The string can include the wildcard character '%' to express like-strategy: starts with (string%), ends with (%string) or contains (%string%).

orderByVariableName

VariableInstanceQuery orderByVariableName()

Order by variable name (needs to be followed by Query.asc() or Query.desc()).

orderByVariableType

VariableInstanceQuery orderByVariableType()

Order by variable type (needs to be followed by Query.asc() or Query.desc()).

orderByActivityInstanceId

VariableInstanceQuery orderByActivityInstanceId()

Order by activity instance id (needs to be followed by Query.asc() or Query.desc()).
