public HistoricVariableInstanceQueryImpl()

HistoricVariableInstanceQueryImpl

public HistoricVariableInstanceQueryImpl(CommandExecutor commandExecutor)

Method Detail

variableId

public HistoricVariableInstanceQuery variableId(String id)

Description copied from interface: HistoricVariableInstanceQuery

Only select the variable with the given Id

Specified by:

variableId in interface HistoricVariableInstanceQuery

Returns:

the query object

processInstanceId

public HistoricVariableInstanceQueryImpl processInstanceId(String processInstanceId)

Description copied from interface: HistoricVariableInstanceQuery

Only select historic process variables with the given process instance.

Specified by:

processInstanceId in interface HistoricVariableInstanceQuery

caseInstanceId

public HistoricVariableInstanceQuery caseInstanceId(String caseInstanceId)

Description copied from interface: HistoricVariableInstanceQuery

Only select historic case variables with the given case instance.

Specified by:

caseInstanceId in interface HistoricVariableInstanceQuery

taskIdIn

public HistoricVariableInstanceQuery taskIdIn(String... taskIds)

Description copied from interface: HistoricVariableInstanceQuery

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

Specified by:

taskIdIn in interface HistoricVariableInstanceQuery

executionIdIn

public HistoricVariableInstanceQuery executionIdIn(String... executionIds)

Description copied from interface: HistoricVariableInstanceQuery

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

Specified by:

executionIdIn in interface HistoricVariableInstanceQuery

caseExecutionIdIn

public HistoricVariableInstanceQuery caseExecutionIdIn(String... caseExecutionIds)

Description copied from interface: HistoricVariableInstanceQuery

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

Specified by:

caseExecutionIdIn in interface HistoricVariableInstanceQuery

activityInstanceIdIn

public HistoricVariableInstanceQuery activityInstanceIdIn(String... activityInstanceIds)

Description copied from interface: HistoricVariableInstanceQuery

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

Specified by:

activityInstanceIdIn in interface HistoricVariableInstanceQuery

variableName

public HistoricVariableInstanceQuery variableName(String variableName)

Description copied from interface: HistoricVariableInstanceQuery

Only select historic process variables with the given variable name.

Specified by:

variableName in interface HistoricVariableInstanceQuery

variableValueEquals

public HistoricVariableInstanceQuery variableValueEquals(String variableName,
                                                         Object variableValue)

Description copied from interface: HistoricVariableInstanceQuery

only select historic process variables with the given name and value

Specified by:

variableValueEquals in interface HistoricVariableInstanceQuery

variableNameLike

public HistoricVariableInstanceQuery variableNameLike(String variableNameLike)

Description copied from interface: HistoricVariableInstanceQuery

Only select historic process variables where the given variable name is like.

Specified by:

variableNameLike in interface HistoricVariableInstanceQuery

ensureVariablesInitialized

protected void ensureVariablesInitialized()

disableBinaryFetching

public HistoricVariableInstanceQuery disableBinaryFetching()

Description copied from interface: HistoricVariableInstanceQuery

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 HistoricVariableInstanceQuery

Returns:

the query builder

disableCustomObjectDeserialization

public HistoricVariableInstanceQuery disableCustomObjectDeserialization()

Description copied from interface: HistoricVariableInstanceQuery

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 HistoricVariableInstanceQuery

executeCount

public long executeCount(CommandContext commandContext)

Specified by:

executeCount in class AbstractQuery<HistoricVariableInstanceQuery,HistoricVariableInstance>

executeList

public List<HistoricVariableInstance> 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 AbstractQuery<HistoricVariableInstanceQuery,HistoricVariableInstance>

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

shouldFetchValue

protected boolean shouldFetchValue(HistoricVariableInstanceEntity entity)

orderByProcessInstanceId

public HistoricVariableInstanceQuery orderByProcessInstanceId()

Specified by:

orderByProcessInstanceId in interface HistoricVariableInstanceQuery

orderByVariableName

public HistoricVariableInstanceQuery orderByVariableName()

Specified by:

orderByVariableName in interface HistoricVariableInstanceQuery

getProcessInstanceId

public String getProcessInstanceId()

getCaseInstanceId

public String getCaseInstanceId()

getActivityInstanceIds

public String[] getActivityInstanceIds()

getTaskIds

public String[] getTaskIds()

getExecutionIds

public String[] getExecutionIds()
