get

public Bytes get(Bytes row,
                 Column column,
                 Bytes defaultValue)

Description copied from interface: SnapshotBase

Retrieves the value (in Bytes) stored at a given row and Column. Returns the passed in defaultValue if does not exist.

Specified by:

get in interface SnapshotBase

defaultValue - this will be returned if row+columns does not exists

                             Column... columns)

Description copied from interface: SnapshotBase

Given a row and list of Columns, retrieves a map that contains the values at those Columns. Only columns that exist will be returned in map.

Specified by:

get in interface SnapshotBase
