java.lang.Object | +--org.apache.commons.beanutils.ResultSetIterator
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.
| Field Summary | |
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 Summary | |
(package private) |
ResultSetIterator(ResultSetDynaClass dynaClass)
Construct an Iterator for the result set being wrapped
by the specified ResultSetDynaClass. |
| Method Summary | |
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(java.lang.String name,
java.lang.String key)
Does the specified mapped property contain a value for the specified key value? |
java.lang.Object |
get(java.lang.String name)
Return the value of a simple property with the specified name. |
java.lang.Object |
get(java.lang.String name,
int index)
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. |
boolean |
hasNext()
Return true if the iteration has more elements. |
java.lang.Object |
next()
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. |
