Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`long`	`getDataVersion()` Each transaction is allocated a serialization point by the transaction coordinator.
`ReadWrite`	`getMode()` What mode is this transaction? This may change from `READ` to `WRITE` in a transactions lifetime.
`TxnState`	`getState()` The transaction lifecycle state
`TxnId`	`getTxnId()` Get the transaction id for this transaction.
`TxnType`	`getTxnType()` What type is this transaction? This is the initial TxnType and does not change during a transaction's lifetime.
`boolean`	`hasFinalised()` Has the transaction gone through all lifecycle states?
`boolean`	`hasFinished()` Has the transaction finished (has commit/abort/end been called)?
`boolean`	`hasStarted()` Has the transaction started?
`default boolean`	`isActiveTxn()` Is this a view of a transaction that is active? Equivalent to `getState() != INACTIVE`
`default boolean`	`isReadTxn()` Is this currently a READ transaction? Promotion may chnage the mode.
`default boolean`	`isWriteTxn()` Is this a currently a WRITE transaction? Convenience operation equivalent to `(getMode() == ReadWrite.WRITE)`

- Method Detail
  - getState
```
TxnState getState()
```
    The transaction lifecycle state
  - getDataVersion
```
long getDataVersion()
```
    Each transaction is allocated a serialization point by the transaction coordinator. Normally, this is related to this number and it increases over time as the data changes. Two readers can have the same serialization point - they are working with the same view of the data.
  - hasStarted
```
boolean hasStarted()
```
    Has the transaction started?
  - hasFinished
```
boolean hasFinished()
```
    Has the transaction finished (has commit/abort/end been called)?
  - hasFinalised
```
boolean hasFinalised()
```
    Has the transaction gone through all lifecycle states?
  - getTxnId
```
TxnId getTxnId()
```
    Get the transaction id for this transaction. Unique within this OS process (JVM) at least .
  - getTxnType
```
TxnType getTxnType()
```
    What type is this transaction? This is the initial TxnType and does not change during a transaction's lifetime.
  - getMode
```
ReadWrite getMode()
```
    What mode is this transaction? This may change from READ to WRITE in a transactions lifetime.
  - isReadTxn
```
default boolean isReadTxn()
```
    Is this currently a READ transaction? Promotion may chnage the mode. Convenience operation equivalent to (getMode() == ReadWrite.READ)
  - isWriteTxn
```
default boolean isWriteTxn()
```
    Is this a currently a WRITE transaction? Convenience operation equivalent to (getMode() == ReadWrite.WRITE)
  - isActiveTxn
```
default boolean isActiveTxn()
```
    Is this a view of a transaction that is active? Equivalent to getState() != INACTIVE
