Method Detail

variables

ExternalTaskQueryTopicBuilder variables(String... variables)

Define variables to fetch with all tasks for the current topic. Calling this method multiple times overrides the previously specified variables.

Parameters:

variables - the variable names to fetch, if null all variables will be fetched

Returns:

this builder

variables

ExternalTaskQueryTopicBuilder variables(List<String> variables)

Define variables to fetch with all tasks for the current topic. Calling this method multiple times overrides the previously specified variables.

Parameters:

variables - the variable names to fetch, if null all variables will be fetched

Returns:

this builder

processInstanceVariableEquals

ExternalTaskQueryTopicBuilder processInstanceVariableEquals(Map<String,Object> variables)

Define a HashMap of variables and their values to filter correlated tasks. Calling this method multiple times overrides the previously specified variables.

Parameters:

variables - a HashMap of the variable names (keys) and the values to filter by

Returns:

this builder

processInstanceVariableEquals

ExternalTaskQueryTopicBuilder processInstanceVariableEquals(String name,
                                                            Object value)

Define a single variable and its name to filter tasks in a topic. Multiple calls to this method add to the existing "variable filters".

Parameters:

name - the name of the variable you want to fetch and query by

value - the value of the variable which you want to filter

Returns:

this builder

businessKey

ExternalTaskQueryTopicBuilder businessKey(String businessKey)

Define business key value to filter external tasks by (Process Instance) Business Key.

Parameters:

businessKey - the value of the Business Key to filter by

Returns:

this builder

enableCustomObjectDeserialization

ExternalTaskQueryTopicBuilder enableCustomObjectDeserialization()

Enable deserialization of variable values that are custom objects. By default, the query will not attempt to deserialize the value of these variables.

Returns:

this builder
