This interface maintains a subset of a resultset by defining a selective list of columns and a row range to be extracted from a full resultset. An implementor of this is provided to a custom data set processor that is capable of converting the resultset subset content into the expected chart dataset format.
Method Summary | |
int |
getColumnCount()
|
int |
getDataType()
Returns the data type associated with a single column resultset subset. |
int |
getDataType(int columnIndex)
Returns the data type of a given column associated with a multi-column resultset subset. |
long |
getSize()
Returns the number of rows associated with this resultset subset instance |
boolean |
hasNext()
Indicates whether another row of data is available without actually moving the cursor |
java.lang.Object[] |
next()
Returns a row of data and advances the resultset subset cursor |
