public class GroovyResultSetExtension extends GroovyObjectSupport
GroovyResultSetExtension implements additional logic for ResultSet. Due to the version incompatibility between java6 and java5 this methods are moved here from the original GroovyResultSet class. The methods in this class are used by the proxy GroovyResultSetProxy, which will try to invoke methods on this class before invoking it on ResultSet.
This class is not intended to be used directly. Should be used through GroovyResultSetProxy only!

Creates a GroovyResultSet implementation.
set
- the result setAdds a new row to the result set
values
- a map containing the mappings for column names and valuesCall the closure once for each row in the result set.
closure
- the closure to perform on each rowSupports integer based subscript operators for accessing at numbered columns starting at zero. Negative indices are supported, they will count from the last column backwards.
index
- is the number of the column to look at starting at 1 Gets the value of the designated column in the current row
of as an Object
.
columnName
- the SQL name of the columnGets the current result set.
Moves the cursor down one row from its current position.
A getResultSet()
cursor is initially positioned
before the first row; the first call to the method
next
makes the first row the current row; the
second call makes the second row the current row, and so on.
If an input stream is open for the current row, a call
to the method next
will
implicitly close it. A getResultSet()
object's
warning chain is cleared when a new row is read.
true
if the new current row is valid;
false
if there are no more rowsTakes a zero based index and convert it into an SQL based 1 based index. A negative index will count backwards from the last column.
index
- the raw requested index (may be negative) Moves the cursor to the previous row in this
getResultSet()
object.
TYPE_FORWARD_ONLY
true
if the cursor is on a valid row;
false
if it is off the result setSupports integer based subscript operators for updating the values of numbered columns starting at zero. Negative indices are supported, they will count from the last column backwards.
index
- is the number of the column to look at starting at 1newValue
- the updated value Updates the designated column with an Object
value.
columnName
- the SQL name of the columnnewValue
