public class ResultSetIterator extends java.lang.Object implements DynaBean, java.util.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.
|
Constructor and Description |

ResultSetIterator(ResultSetDynaClass dynaClass)
Construct an
Iterator for the result set being wrapped
by the specified ResultSetDynaClass . |

Return the value of an indexed property with the specified name.
|
java.lang.Object |
get(java.lang.String name,
java.lang.String key)
Return the value of a mapped property with the specified name,
or
null if there is no value for the specified key. |
DynaClass |
getDynaClass()
Return the
DynaClass instance that describes the set of
properties available for this DynaBean. |

Return
true if the iteration has more elements. |
DynaBean |

Return the next element in the iteration.
|
void |
remove()
Remove the current element from the iteration.
|
void |
remove(java.lang.String name,
java.lang.String key)
Remove any existing value for the specified key on the
specified mapped property.
|
void |
set(java.lang.String name,
int index,
java.lang.Object value)
Set the value of an indexed property with the specified name.
|
void |
set(java.lang.String name,
java.lang.Object value)
Set the value of a simple property with the specified name.
|
void |
set(java.lang.String name,
java.lang.String key,
java.lang.Object value)
Set the value of a mapped property with the specified name.
