Method Detail

getOriginalFile

OriginalFile getOriginalFile(Ice.Current __current)
                      throws ServerError

Throws:

ServerError

Column[] getHeaders(Ice.Current __current)
             throws ServerError

Returns empty columns.

Parameters:

__current - The Current object for the invocation.

Throws:

ServerError

getNumberOfRows

long getNumberOfRows(Ice.Current __current)
              throws ServerError

Throws:

ServerError

getWhereList

long[] getWhereList(java.lang.String condition,
                    java.util.Map<java.lang.String,RType> variables,
                    long start,
                    long stop,
                    long step,
                    Ice.Current __current)
             throws ServerError

http://www.pytables.org/docs/manual/apb.html Leave all three of start, stop, step to 0 to disable. TODO:Test effect of returning a billion rows matching getWhereList()

Parameters:

__current - The Current object for the invocation.

Throws:

ServerError

readCoordinates

Data readCoordinates(long[] rowNumbers,
                     Ice.Current __current)
              throws ServerError

Read the given rows of data.

Parameters:

rowNumbers - must contain at least one element or an ApiUsageException will be thrown.

__current - The Current object for the invocation.

Throws:

ServerError

read

Data read(long[] colNumbers,
          long start,
          long stop,
          Ice.Current __current)
   throws ServerError

http://www.pytables.org/docs/manual/ch04.html#Table.read

Parameters:

__current - The Current object for the invocation.

Throws:

ServerError

slice

Data slice(long[] colNumbers,
           long[] rowNumbers,
           Ice.Current __current)
    throws ServerError

Simple slice method which will return only the given columns and rows in the order supplied. If colNumbers or rowNumbers is empty (or None), then all values will be returned.

Python examples:

 data = table.slice(None, None)
 assert len(data.rowNumbers) == table.getNumberOfRows()

 data = table.slice(None, \[3,2,1])
 assert data.rowNumbers == \[3,2,1]

__current - The Current object for the invocation.

Throws:

ServerError

      throws ServerError

Throws:

ServerError

update

void update(Data modifiedData,
            Ice.Current __current)
     throws ServerError

Allows the user to modify a Data instance passed back from a query method and have the values modified. It is critical that the Data.lastModification and the Data.rowNumbers fields are properly set. An exception will be thrown if the data has since been modified.

Parameters:

__current - The Current object for the invocation.

Throws:

ServerError
