uk.ac.starlink.ttools.cone.UploadConeTable

All Implemented Interfaces:

Closeable, AutoCloseable, StarTable

public class UploadConeTable
extends AbstractStarTable

Table suitable for uploading based on a sequence of positional queries and an RowMapper. The resulting table contains just three columns: ID, RA, Dec.

This is a one-shot sequential table - only one row sequence may be taken out from it.

Method Detail

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 interface: StarTable

Returns the number of rows in this table, if known. If the number of rows cannot be (easily) determined, a value of -1 will be returned.

Specified by:

getRowCount in interface StarTable

Specified by:

getRowCount in class AbstractStarTable

Returns:

the number of rows, or -1

getRowSequence

public RowSequence getRowSequence()
                           throws IOException

Description copied from interface: StarTable

Returns an object which can iterate over all the rows in the table sequentially. Each such returned object is safe for use within a single thread, but not in general from multiple threads concurrently.

Specified by:

getRowSequence in interface StarTable

Specified by:

getRowSequence in class AbstractStarTable

Returns:

new RowSequence

Throws:

IOException - if there is an error providing access

close

public void close()
           throws IOException

Description copied from class: AbstractStarTable

The AbstractStarTable implementation of this method does nothing.

Specified by:

Specified by:

close in interface AutoCloseable

Specified by:

close in interface StarTable

Overrides:

close in class AbstractStarTable

Throws:

IOException
