public class ResultSetIterator extends Object implements DynaBean, Iterator<DynaBean>
Implementation of java.util.Iterator
returned by the
iterator()
method of ResultSetDynaClass
. Each
object returned by this iterator will be a DynaBean
that
represents a single row from the result set being wrapped.
Modifier and Type | Field and Description |
---|---|
protected boolean |
current
Flag indicating whether the result set is currently positioned at a
row for which we have not yet returned an element in the iteration.
|
protected ResultSetDynaClass |
dynaClass
The
ResultSetDynaClass we are associated with. |
protected boolean |
eof
Flag indicating whether the result set has indicated that there are
no further rows.
|
Modifier and Type | Method and Description |

protected void |
advance()
Advance the result set to the next row, if there is not a current
row (and if we are not already at eof).
|
boolean |
contains(String name,
String key)
Does the specified mapped property contain a value for the specified
key value?

Return the value of a mapped property with the specified name,
or
null if there is no value for the specified key. |
DynaClass |
getDynaClass()

DynaClass instance that describes the set of
properties available for this DynaBean. |
boolean |
hasNext()
Return
true if the iteration has more elements. |
DynaBean |
