ScopeWALEntryFilter

public ScopeWALEntryFilter()

方法详细资料

filter

public WAL.Entry filter(WAL.Entry entry)

从接口复制的说明: WALEntryFilter

Applies the filter, possibly returning a different Entry instance. If null is returned, the entry will be skipped.

Notice that you are free to modify the cell list of the give entry, but do not change the content of the cell, it may be used by others at the same time(and usually you can not modify a cell unless you cast it to the implementation class, which is not a good idea).

指定者:

filter 在接口中 WALEntryFilter

参数:

entry - Entry to filter

返回:

a (possibly modified) Entry to use. Returning null or an entry with no cells will cause the entry to be skipped for replication.

filterCell

public Cell filterCell(WAL.Entry entry,
                       Cell cell)

从接口复制的说明: WALCellFilter

Applies the filter, possibly returning a different Cell instance. If null is returned, the cell will be skipped.

指定者:

filterCell 在接口中 WALCellFilter

参数:

entry - Entry which contains the cell

cell - Cell to filter

返回:

a (possibly modified) Cell to use. Returning null will cause the cell to be skipped for replication.
