public class ResultSetIterator extends Object implements DynaBean, Iterator

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

Flag indicating whether the result set is currently positioned at a row for which we have not yet returned an element in the iteration.
The ResultSetDynaClass we are associated with.
Flag indicating whether the result set has indicated that there are no further rows.
Advance the result set to the next row, if there is not a current row (and if we are not already at eof).
Throws: SQLException if the result set throws an exception
Parameters: name Name of the property to check key Name of the key to check
Returns: true
if the mapped property contains a value for
the specified key, otherwise
false
Throws: IllegalArgumentException if there is no property of the specified name
Parameters: name Name of the property whose value is to be retrieved
Returns: The property's value
Throws: IllegalArgumentException if there is no property of the specified name
Parameters: name Name of the property whose value is to be retrieved index Index of the value to be retrieved
Returns: The indexed property's value
Throws: IllegalArgumentException if there is no property of the specified name IllegalArgumentException if the specified property exists, but is not indexed IndexOutOfBoundsException if the specified index is outside the range of the underlying property NullPointerException if no array or List has been initialized for this property
null
if there is no value for the specified key.
Parameters: name Name of the property whose value is to be retrieved key Key of the value to be retrieved
Returns: The mapped property's value
Throws: IllegalArgumentException if there is no property of the specified name IllegalArgumentException if the specified property exists, but is not mapped
DynaClass
instance that describes the set of
properties available for this DynaBean.
Returns: The associated DynaClass
Return true
if the iteration has more elements.
Returns: true
if the result set has another
row, otherwise false
Return the next element in the iteration.
Returns: advance to the new row and return this
Parameters: name Name of the property for which a value is to be removed key Key of the value to be removed
Throws: IllegalArgumentException if there is no property of the specified name
Remove the current element from the iteration. This method is not supported.
Parameters: name Name of the property whose value is to be set value Value to which this property is to be set
Throws: ConversionException if the specified value cannot be converted to the type required for this property IllegalArgumentException if there is no property of the specified name NullPointerException if an attempt is made to set a primitive property to null
Parameters: name Name of the property whose value is to be set index Index of the property to be set value Value to which this property is to be set
Throws: ConversionException if the specified value cannot be converted to the type required for this property IllegalArgumentException if there is no property of the specified name IllegalArgumentException if the specified property exists, but is not indexed IndexOutOfBoundsException if the specified index is outside the range of the underlying property
Parameters: name Name of the property whose value is to be set key Key of the property to be set value Value to which this property is to be set
Throws: ConversionException if the specified value cannot be converted to the type required for this property IllegalArgumentException if there is no property of the specified name IllegalArgumentException if the specified property exists, but is not mapped
