Constructor.
|
Modifier and Type | Method | Description |
---|---|---|
abstract C |
createCalculation(long irow) |
Creates the calculation object for the given row of the input table.
|
abstract C |
createCalculation(RowSequence baseSeq) |
Creates the calculation object for the current row of the input table.
|
StarTable |
getBaseTable() |
Returns the input table on which this table is based.
|
java.lang.Object |
getCell(long irow,
int icol) |
The AbstractStarTable implementation of this method throws an
UnsupportedOperationException, since unless otherwise
provided there is no random access.
|
int |
getColumnCount() |
Returns the number of columns in this table.
|
ColumnInfo |
getColumnInfo(int icol) |
Returns the object describing the data in a given column.
|
java.lang.Object[] |
getRow(long irow) |
The AbstractStarTable implementation of this method
constructs a row by repeated invocation of
AbstractStarTable.getCell(long, int) . |
long |
getRowCount() |
Returns the number of rows in this table, if known.
|
RowSequence |
getRowSequence() |
Returns an object which can iterate over all the rows in the table
sequentially.
|
boolean |
isRandom() |
The AbstractStarTable implementation of this method
returns false.
