Iterator for BSON objects
Class BSONIter( bson )
| bson | A BSON object |
Example:
iter = BSONIter( bson )
while iter.next()
doSomething( iter.key(), iter.value() )
end
The iterator copies data from given BSON object, and is completely independant and cannot be changed or updated. (This is of course suboptimal and could be optimized later.)
| Methods | |
| find | Return true when (and set iterator position where) name is found in the BSON. |
| key | Get the current BSON key string |
| next | Return true if there is more data to iterate over |
| reset | Reset to start of iterator. |
| value | Get the current BSON value |
Return true when (and set iterator position where) name is found in the BSON.
BSONIter.find( name )
| name | Key name |
| Return | True if the key can be found, false otherwise. |
If false is returned, iterator is at end (and you may have to reset it). This method does a reset before searching.
Get the current BSON key string
BSONIter.key()
| Return | The current key. |
Return true if there is more data to iterate over
BSONIter.next()
| Return | True if the iterator could advance, false if it was the last element. |
Reset to start of iterator.
BSONIter.reset()
Get the current BSON value
BSONIter.value()
| Return | The current value. |
