方法概要

限定符和类型	方法和说明
protected void	preCloseWriter(StoreFileWriter writer) Subclasses override this method to be called before we close the give writer.
protected void	preCommitWriters() Subclasses override this method to be called at the end of a successful sequence of append; all appends are processed before this method is called.
protected abstract void	preCommitWritersInternal()
protected void	sanityCheckLeft(byte[] left, Cell cell) Subclasses can call this method to make sure the first KV is within multi-writer range.
protected void	sanityCheckRight(byte[] right, Cell cell) Subclasses can call this method to make sure the last KV is within multi-writer range.
void	setNoStripeMetadata()

指定者:

writers 在类中 AbstractMultiFileWriter

preCommitWritersInternal

protected abstract void preCommitWritersInternal()
                                          throws IOException

抛出:

IOException

preCommitWriters

protected final void preCommitWriters()
                               throws IOException

从类复制的说明: AbstractMultiFileWriter

Subclasses override this method to be called at the end of a successful sequence of append; all appends are processed before this method is called.

覆盖:

preCommitWriters 在类中 AbstractMultiFileWriter

抛出:

IOException

preCloseWriter

protected void preCloseWriter(StoreFileWriter writer)
                       throws IOException

从类复制的说明: AbstractMultiFileWriter

Subclasses override this method to be called before we close the give writer. Usually you can append extra metadata to the writer.

覆盖:

preCloseWriter 在类中 AbstractMultiFileWriter

抛出:

IOException

sanityCheckLeft

protected void sanityCheckLeft(byte[] left,
                               Cell cell)
                        throws IOException

Subclasses can call this method to make sure the first KV is within multi-writer range.

参数:

left - The left boundary of the writer.

cell - The cell whose row has to be checked.

抛出:

IOException

sanityCheckRight

protected void sanityCheckRight(byte[] right,
                                Cell cell)
                         throws IOException

Subclasses can call this method to make sure the last KV is within multi-writer range.

参数:

right - The right boundary of the writer.

抛出:

IOException
