List of seekTo() Examples

Examples of seekTo()

org.apache.cassandra.db.FileStruct.seekTo()
org.apache.cassandra.io.SSTableScanner.seekTo()
org.apache.cassandra.io.sstable.SSTableScanner.seekTo()
org.apache.hadoop.hbase.io.hfile.HFileScanner.seekTo()
SeekTo or just before the passed key. Examine the return code to figure whether we found the key or not. Consider the key stream of all the keys in the file, k[0] .. k[n], where there are n keys in the file. @param key Key to find. @return -1, if key < k[0], no position;0, such that k[i] = key and scanner is left in position i; and 1, such that k[i] < key, and scanner is left in position i. Furthermore, there may be a k[i+1], such that k[i] < key < k[i+1] but there may not be a k[i+1], and next() will return false (EOF). @throws IOException
