Method Details

toString

public String toString()

Overrides:

toString in class Object

getSizeInBytes

public long getSizeInBytes()

Description copied from class: LocalAppendableColumn

Get the size (in bytes) of the underlying data file region for this column.

Specified by:

getSizeInBytes in class LocalAppendableColumn<DATA_TYPE>

Returns:

The size (in bytes) of the underlying data file region

force

public void force()

Description copied from interface: BufferedAppendable

Force all flushed data to be persisted to permanent storage. Will consistently and atomically persist the last prepared checkpoint in implementations that implement BufferedAppendable.prepareCheckpoint(). Does not imply BufferedAppendable.flush(), as this is a distinct operation in all implementations. May be called concurrently by threads other than the "writing thread".

Specified by:

force in interface AppendableColumn<DATA_TYPE>

Specified by:

force in interface BufferedAppendable

close

public void close()

Description copied from interface: BufferedAppendable

Flush all appended data to the underlying store, release any resources held, and force all appended data to be persisted to permanent storage. This should be the final access to this appendable (if successful) with the exception of any asynchronous BufferedAppendable.force() operations. A BufferedAppendable.release() is appropriate afterwards, especially on error.

Specified by:

close in interface AppendableColumn<DATA_TYPE>

Specified by:

close in interface BufferedAppendable

flush

public void flush()

Description copied from interface: BufferedAppendable

Write all appended data to the underlying store and prepare for subsequent writes. Does not imply BufferedAppendable.force().

Specified by:

flush in interface BufferedAppendable

release

public void release()

Description copied from interface: BufferedAppendable

Release any resources held. Called after an error in preparation for termination. For external callers, this should be done as the final access to this column with the exception of any asynchronous BufferedAppendable.force() operations.

Specified by:

release in interface BufferedAppendable

doneAppending

public void doneAppending()

Description copied from interface: BufferedAppendableColumn

Optionally called before BufferedAppendable.close() to release any resources that may be released prior to BufferedAppendable.close(). No data should be appended after this method is invoked.

Specified by:

doneAppending in interface BufferedAppendableColumn<DATA_TYPE>

inTransaction

public boolean inTransaction()

Specified by:

inTransaction in interface TableTransactionProcessor

Returns:

True if this processor is currently in a transaction, else false

startTransaction

public void startTransaction()

Description copied from interface: TableTransactionProcessor

Begin a new transaction. Causes any existing pending transaction to be aborted.

Specified by:

startTransaction in interface TableTransactionProcessor

abortTransaction

public void abortTransaction()

Description copied from interface: TableTransactionProcessor

Abort the current pending transaction.

This should not be called if there is no current transaction.

Specified by:

abortTransaction in interface TableTransactionProcessor

finishTransaction

public void finishTransaction()

Description copied from interface: TableTransactionProcessor

Finish the current pending transaction.

This makes the rows that were part of the transaction eligible to be made visible and durable, but does not in itself make them visible or durable.

This should not be called if there is no current transaction.

Specified by:

finishTransaction in interface TableTransactionProcessor
