  - - uk.ac.starlink.table.jdbc.RandomResultSetStarTable

All Implemented Interfaces:

StarTable
```
public class RandomResultSetStarTable
extends RandomStarTable
```
StarTable implementation based on a random-access ResultSet. Such results sets have a type of ResultSet.TYPE_SCROLL_* and are generally produced from by using a Statement which has been constructed using corresponding type. This implementation is thread-safe.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`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.
`java.util.List`	`getColumnAuxDataInfos()` Goes through the table columns (`ColumnInfo` objects) and picks out all the AuxData items which exist, generalising where necessary and returning a union of them in alphabetical order by name.
`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.sql.ResultSet`	`getResultSet()` Returns the result set on which this table is built.
`java.lang.Object[]`	`getRow(long lrow)` The `AbstractStarTable` implementation of this method constructs a row by repeated invocation of `AbstractStarTable.getCell(long, int)`.
`long`	`getRowCount()` The number of rows in this table.

  - getResultSet
```
public java.sql.ResultSet getResultSet()
```
    Returns the result set on which this table is built.
    
    Returns:
    
    result set
  - getColumnCount
```
public int getColumnCount()
```
    Description copied from interface: StarTable
    
    Returns the number of columns in this table.
    
    Specified by:
    
    getColumnCount in interface StarTable
    
    Specified by:
    
    getColumnCount in class AbstractStarTable
    
    Returns:
    
    the number of columns
  - getColumnInfo
```
public ColumnInfo getColumnInfo(int icol)
```
    Description copied from interface: StarTable
    
    Returns the object describing the data in a given column.
    
    Specified by:
    
    getColumnInfo in interface StarTable
    
    Specified by:
    
    getColumnInfo in class AbstractStarTable
    
    Parameters:
    
    icol - the column for which header information is required
    
    Returns:
    
    a ValueInfo object for column icol
  - getRowCount
```
public long getRowCount()
```
    Description copied from class: RandomStarTable
    
    The number of rows in this table. Implementations must supply a non-negative return value.
    
    Specified by:
    
    getRowCount in interface StarTable
    
    Specified by:
    
    getRowCount in class RandomStarTable
    
    Returns:
    
    the number of rows in the table
  - getColumnAuxDataInfos
```
public java.util.List getColumnAuxDataInfos()
```
    Description copied from class: AbstractStarTable
    
    Goes through the table columns (ColumnInfo objects) and picks out all the AuxData items which exist, generalising where necessary and returning a union of them in alphabetical order by name. Subclasses should override this if they can do better, for instance providing an order for the keys.
    
    Specified by:
    
    getColumnAuxDataInfos in interface StarTable
    
    Overrides:
    
    getColumnAuxDataInfos in class AbstractStarTable
    
    Returns:
    
    a list of all the auxiliary metadata ValueInfo items which in fact crop up in column metadata

    ColumnInfo.getAuxData()
  - getCell
```
public java.lang.Object getCell(long lrow,
                                int icol)
                         throws java.io.IOException
```
    Description copied from class: AbstractStarTable
    
    The AbstractStarTable implementation of this method throws an UnsupportedOperationException, since unless otherwise provided there is no random access.
    
    Specified by:
    
    getCell in interface StarTable
    
    Overrides:
    
    getCell in class AbstractStarTable
    
    Parameters:
    
    lrow - the index of the cell's row
    
    icol - the index of the cell's column
    
    Returns:
    
    the contents of this cell
    
    Throws:
    
    java.io.IOException - if there is an error reading the data
  - getRow

                          throws java.io.IOException
```
    Description copied from class: AbstractStarTable
    
    The AbstractStarTable implementation of this method constructs a row by repeated invocation of AbstractStarTable.getCell(long, int).
    
    Specified by:
    
    getRow in interface StarTable
    
    Overrides:
    
    getRow in class AbstractStarTable
    
    Parameters:
    
    lrow - the index of the row to retrieve
    
    Returns:
    
    an array of the objects in each cell in row irow
    
    Throws:
    
    java.io.IOException - if there is an error reading the data
