◆ setItem()
| bool ripple::SHAMapLeafNode::setItem | ( | boost::intrusive_ptr< SHAMapItem const > | i | ) |
Set the item that this node points to and update the node's hash.
- Parameters
-
i the new item
- Returns
- false if the change was, effectively, a noop (that is, if the hash was unchanged); true otherwise.

◆ getHash()
|
inherited |
Return the hash of this node.
Definition at line 143 of file SHAMapTreeNode.h.
◆ getType()
|
pure virtualinherited |
Determines the type of node.
Implemented in ripple::SHAMapInnerNode, ripple::SHAMapTxPlusMetaLeafNode, ripple::SHAMapAccountStateLeafNode, and ripple::SHAMapTxLeafNode.
◆ serializeForWire()
|

Definition at line 56 of file SHAMapTreeNode.h.
◆ cowid_
|
protectedinherited |
Determines the owning SHAMap, if any.
Used for copy-on-write semantics.
If this value is 0, the node is not dirty and does not need to be flushed. It is eligible for sharing and may be included multiple SHAMap instances.
