Method Detail

addBufferedRowsback to summary
public abstract void addBufferedRows(List<String> bufferNames)

Add all the index data from the buffers to the index. The index will typically use merge sort to add the data more quickly in sorted order.

Parameters
bufferNames:List<String>

the names of the temporary storage

addRowsToBufferback to summary
public abstract void addRowsToBuffer(List<Row> rows, String bufferName)

Add the rows to a temporary storage (not to the index yet). The rows are sorted by the index columns. This is to more quickly build the index.

Parameters
rows:List<Row>

the rows

bufferName:String

the name of the temporary storage

getDiskSpaceUsedback to summary
public long getDiskSpaceUsed(boolean approximate)

Overrides org.h2.index.Index.getDiskSpaceUsed.

Doc from org.h2.index.Index.getDiskSpaceUsed.

Get the used disk space for this index.

Parameters
approximate:boolean

true to return quick approximation

Returns:long

the estimated number of bytes
