Interface LinearizabilityChecker.SequentialSpec

All Known Subinterfaces:

LinearizabilityChecker.KeyedSpec

Enclosing class:

LinearizabilityChecker

public static interface LinearizabilityChecker.SequentialSpec

Sequential specification of a datatype. Used as input for the linearizability checker. All parameter and return values should be immutable and have proper equals / hashCode implementations

Method Summary

Modifier and Type	Method	Description
Object	initialState()	Returns the initial state of the datatype
Optional<Object>	nextState(Object currentState, Object input, Object output)	Next-state function, checking whether transitioning the datatype in the given state under the provided input and output is valid.
default Collection<List<LinearizabilityChecker.Event>>	partition(List<LinearizabilityChecker.Event> events)	For compositional checking, the history can be partitioned into sub-histories

Method Details

initialState

Object initialState()

Returns the initial state of the datatype

nextState

Optional<Object> nextState(Object currentState,
 Object input,
 Object output)

Next-state function, checking whether transitioning the datatype in the given state under the provided input and output is valid.

Parameters:

currentState - the current state of the datatype

input - the input, associated with the given invocation event

output - the output, associated with the corresponding response event

Returns:

the next state, if the given current state, input and output are a valid transition, or Optional.empty() otherwise

partition

default Collection<List<LinearizabilityChecker.Event>> partition(List<LinearizabilityChecker.Event> events)

For compositional checking, the history can be partitioned into sub-histories

Parameters:

events - the history of events to partition

Returns:

the partitioned history
