Method Detail

read

public Optional<org.camunda.bpm.engine.variable.value.TypedValue> read(StepExecutionContext stepExecutionContext,
                                                                       String variableName)

Description copied from interface: ReadStrategy

Returns the TypedValue of the variable variableName.

Specified by:

read in interface ReadStrategy

Parameters:

stepExecutionContext - the context of this strategy's execution

variableName - the variable to read

Returns:

the TypedValue or Optional.empty()

remove

public void remove(StepExecutionContext stepExecutionContext,
                   String variableName)

Description copied from interface: DeleteStrategy

Removes a variable. This is used in the context of renaming variables.

This method is placed in the read interface because it's the source variable that is to be deleted. WriteStrategys might not know about the source variable and are therefore unable to delete it.

Specified by:

remove in interface DeleteStrategy

Parameters:

stepExecutionContext - the context of this strategy's execution

variableName - the variable to delete
