Description
Interface Summary | |
ProcessingFilter | Defines a type of filter-like processing which can be done on a StarTable. |
ProcessingStep | Represents one step of a table processing pipeline. |
Class Summary | |
AddColumnFilter | Table filter for adding a single synthetic column. |
AddJELColumnTable | Wrapper table which adds a single column, defined by a JEL expression. |
CacheFilter | Processing step which caches the current table in a disk or memory
cache (according to the default StoragePolicy ). |
ColStats | Accumulates statistics for the values in a given column. |
ColumnIdentifier | Can identify columns of a table using string identifiers. |
ColumnSortFilter | Sort processing step which sorts on one or more column identifiers. |
CopyMode | Processing mode which writes out a table. |
CountMode | Processing mode which just counts the number of rows and columns and writes a summary to the output stream. |
DeleteColumnFilter | Table filter for deleting a single column. |
DummyJELRowReader | JELRowReader which can't actually read any rows. |
EveryFilter | |
EveryTable | Wrapper table which looks at only every n'th row. |
ExplodeFilter | Table filter for replacing every N-element array-valued columns with N scalar-valued columns. |
ExpressionSortFilter | Processing filter which sorts on one or more JEL expressions. |
HeadFilter | Filter for picking only the first few rows of a table. |
HeadTable | Wrapper table implementation which only contains the first N rows of its base table. |
JdbcMode | Mode for writing a table as a new table in a JDBC-connected database. |
JELRowReader | An object which is able to read cell values by column name or number. |
JELSelectorTable | Sequential table which selects rows on the basis of a JEL-interpreted expression. |
JELUtils | This class provides some utility methods for use with the JEL expression compiler. |
KeepColumnFilter | Table filter for selecting a number of columns and discarding the rest. |
MetadataMode | Processing mode which summarises table metadata. |
ProcessingMode | Interface defining the final element of a table processing pipeline - the one which disposes of the table in some way. |
RandomFilter | Processing filter that makes sure any RowSequence taken out on a table uses calls to random table access methods. |
RandomJELRowReader | Implements JELRowReader for a random access table. |
SelectFilter | Table filter for selecting only certain rows using a JEL expression. |
SequentialFilter | Processing filter that makes sure any table filtered by it does not have random access. |
SequentialJELRowReader | Implements JELRowReader for sequential access to a table. |
StatsMode | Processing mode for calculating statistics on a table. |
StreamRowStore | RowStore implementation whose returned table reads from a stream. |
TablePipe | Pipeline tool for generic table manipulation. |
TableTask | Generic superclass for table processing utilities. |
TailFilter | Filter for picking only the last few rows of a table. |
TailTable | Wrapper table implementation which only contains the last N rows of its base table. |
Exception Summary | |
StreamRereadException | Exception thrown to indicate that the requested data are unavailable since they come from a non-rewindable stream and have already been read once. |
Command-line tools for table manipulation.
