Method Detail

variableId

public VariableInstanceQuery variableId(String id)

Description copied from interface: VariableInstanceQuery

Only select the variable with the given Id

Specified by:

variableId in interface VariableInstanceQuery

Returns:

the query object

variableName

public VariableInstanceQuery variableName(String variableName)

Description copied from interface: VariableInstanceQuery

Only select variable instances which have the variable name.

Specified by:

variableName in interface VariableInstanceQuery

variableNameIn

public VariableInstanceQuery variableNameIn(String... variableNames)

Description copied from interface: VariableInstanceQuery

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

Specified by:

variableNameIn in interface VariableInstanceQuery

variableNameLike

public VariableInstanceQuery variableNameLike(String variableNameLike)

Description copied from interface: VariableInstanceQuery

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%).

Specified by:

variableNameLike in interface VariableInstanceQuery

executionIdIn

public VariableInstanceQuery executionIdIn(String... executionIds)

Description copied from interface: VariableInstanceQuery

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

Specified by:

executionIdIn in interface VariableInstanceQuery

processInstanceIdIn

public VariableInstanceQuery processInstanceIdIn(String... processInstanceIds)

Description copied from interface: VariableInstanceQuery

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

Specified by:

processInstanceIdIn in interface VariableInstanceQuery

caseExecutionIdIn

public VariableInstanceQuery caseExecutionIdIn(String... caseExecutionIds)

Description copied from interface: VariableInstanceQuery

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

Specified by:

caseExecutionIdIn in interface VariableInstanceQuery

caseInstanceIdIn

public VariableInstanceQuery caseInstanceIdIn(String... caseInstanceIds)

Description copied from interface: VariableInstanceQuery

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

Specified by:

caseInstanceIdIn in interface VariableInstanceQuery

taskIdIn

public VariableInstanceQuery taskIdIn(String... taskIds)

Description copied from interface: VariableInstanceQuery

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

Specified by:

taskIdIn in interface VariableInstanceQuery

variableScopeIdIn

public VariableInstanceQuery variableScopeIdIn(String... variableScopeIds)

Description copied from interface: VariableInstanceQuery

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

Specified by:

variableScopeIdIn in interface VariableInstanceQuery

activityInstanceIdIn

public VariableInstanceQuery activityInstanceIdIn(String... activityInstanceIds)

Description copied from interface: VariableInstanceQuery

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

Specified by:

activityInstanceIdIn in interface VariableInstanceQuery

disableBinaryFetching

public VariableInstanceQuery disableBinaryFetching()

Description copied from interface: VariableInstanceQuery

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.

Specified by:

disableBinaryFetching in interface VariableInstanceQuery

Returns:

the query builder

disableCustomObjectDeserialization

public VariableInstanceQuery disableCustomObjectDeserialization()

Description copied from interface: VariableInstanceQuery

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.

Specified by:

disableCustomObjectDeserialization in interface VariableInstanceQuery

tenantIdIn

public VariableInstanceQuery tenantIdIn(String... tenantIds)

Description copied from interface: VariableInstanceQuery

Only select variable instances with one of the given tenant ids.

Specified by:

tenantIdIn in interface VariableInstanceQuery

orderByVariableName

public VariableInstanceQuery orderByVariableName()

Description copied from interface: VariableInstanceQuery

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

Specified by:

orderByVariableName in interface VariableInstanceQuery

orderByVariableType

public VariableInstanceQuery orderByVariableType()

Description copied from interface: VariableInstanceQuery

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

Specified by:

orderByVariableType in interface VariableInstanceQuery

orderByActivityInstanceId

public VariableInstanceQuery orderByActivityInstanceId()

Description copied from interface: VariableInstanceQuery

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

Specified by:

orderByActivityInstanceId in interface VariableInstanceQuery

orderByTenantId

public VariableInstanceQuery orderByTenantId()

Description copied from interface: VariableInstanceQuery

Order by tenant id (needs to be followed by Query.asc() or Query.desc()). Note that the ordering of variable instances without tenant id is database-specific.

Specified by:

orderByTenantId in interface VariableInstanceQuery

hasExcludingConditions

protected boolean hasExcludingConditions()

Description copied from class: AbstractQuery

Whether or not the query has excluding conditions. If the query has excluding conditions, (e.g. task due date before and after are excluding), the SQL query is avoided and a default result is returned. The returned result is the same as if the SQL was executed and there were no entries.

Overrides:

hasExcludingConditions in class AbstractQuery<VariableInstanceQuery,VariableInstance>

Returns:

true if the query does have excluding conditions, false otherwise

executeCount

public long executeCount(CommandContext commandContext)

Specified by:

executeCount in class AbstractVariableQueryImpl<VariableInstanceQuery,VariableInstance>

executeList

public List<VariableInstance> executeList(CommandContext commandContext,
                                 Page page)

Description copied from class: AbstractQuery

Executes the actual query to retrieve the list of results.

Specified by:

executeList in class AbstractVariableQueryImpl<VariableInstanceQuery,VariableInstance>

page - used if the results must be paged. If null, no paging will be applied.
