Member Data Documentation

◆ item_

boost::intrusive_ptr<SHAMapItem const> ripple::SHAMapLeafNode::item_
protectedinherited

Definition at line 35 of file SHAMapLeafNode.h.

◆ hash_

SHAMapHash ripple::SHAMapTreeNode::hash_
protectedinherited

Definition at line 56 of file SHAMapTreeNode.h.

◆ cowid_

std::uint32_t ripple::SHAMapTreeNode::cowid_
