Method Detail

includeDirectory

void includeDirectory(java.nio.file.Path dir)

Include sstables under the directory

Parameters:

dir - directory that contains sstables

includeSSTable

void includeSSTable(java.util.List<java.nio.file.Path> sstableComponents)

Include the sstable components of an individual SSTable

Parameters:

sstableComponents - sstable components

includeFileDigests

void includeFileDigests(java.util.Map<java.nio.file.Path,Digest> fileDigests)

Include the digests of the files

Parameters:

fileDigests - digest of the files

fileDigests

java.util.Map<java.nio.file.Path,Digest> fileDigests(java.util.Set<java.nio.file.Path> files)

Get the file digests of the input files

Parameters:

files - files to gather the digests

Returns:

file digests of the input files

totalSize

long totalSize()

Returns:

total size of all sstables included

peek

SSTableCollector.SSTableFilesAndRange peek()

Get an SSTable from the collector, but do not remove it

Returns:

sstable or null if the collector is empty

consumeOne

SSTableCollector.SSTableFilesAndRange consumeOne()

Get an SSTable from the collector and remove it

Returns:

sstable or null if the collector is empty

isEmpty

boolean isEmpty()

Returns:

true if the collector is empty; otherwise, false
