ServiceContext (Atomix API Reference (3.0.0-rc4))

All Known Implementing Classes:

RaftServiceContext
```
public interface ServiceContext
```
State machine context.
The context is reflective of the current position and state of the Raft state machine. In particular, it exposes the current approximate time and all open Sessions.

`LogicalClock`	`logicalClock()` Returns the state machine's logical clock.
`<C extends ServiceConfig> C`	`serviceConfig()` Returns the service configuration.
`PrimitiveId`	`serviceId()` Returns the state machine identifier.
`String`	`serviceName()` Returns the state machine name.

`WallClock`	`wallClock()` Returns the state machine's wall clock.

- Method Detail
  - serviceId
```
PrimitiveId serviceId()
```
    Returns the state machine identifier.
    
    Returns:
    
    The unique state machine identifier.
  - serviceName
```
String serviceName()
```
    Returns the state machine name.
    
    Returns:
    
    The state machine name.
  - serviceType
```
PrimitiveType serviceType()
```
    Returns the state machine type.
    
    Returns:
    
    The state machine type.
  - serviceConfig
```
<C extends ServiceConfig> C serviceConfig()
```
    Returns the service configuration.
    
    Type Parameters:
    
    C - the configuration type
    
    Returns:
    
    the service configuration
  - currentIndex
```
long currentIndex()
```
    Returns the current state machine index.
    The state index is indicative of the index of the current operation being applied to the server state machine. If a query is being applied, the index of the last command applied will be used.
    
    Returns:
    
    The current state machine index.
  - currentSession
```
Session currentSession()
```
    Returns the current session.
    
    Returns:
    
    the current session
  - currentOperation
```
OperationType currentOperation()
```
    Returns the current operation type.
    
    Returns:
    
    the current operation type
  - logicalClock
```
LogicalClock logicalClock()
```
    Returns the state machine's logical clock.
    
    Returns:
    
    The state machine's logical clock.
  - wallClock
```
WallClock wallClock()
```
    Returns the state machine's wall clock.
    
    Returns:
    
    The state machine's wall clock.
