java.lang.Object |
getCell(long lrow,
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 lrow)
The
AbstractStarTable implementation of this method
constructs a row by repeated invocation of AbstractStarTable.getCell(long, int) . |
RowAccess |
getRowAccess()
Returns an object which can provide random access to this
table's data, if random access is implemented.
|
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 . |
