- c++ - Boost PropertyTree: check if child exists - Stack Overflow
While these solutions might appear to avoid iterating over the tree, just keep in mind that under the covers they are still doing exactly that, so you are making your algorithm potentially n^2 if you are concerned about performance and have memory to spare, you could use a map container for quick lookups
- c++ - How to iterate a boost property tree? - Stack Overflow
An addition to the answer How to iterate a boost property tree?: In the C++11 style range based for for (auto node : tree), each node is a std::pair<key_type, property_tree> Whereas in the manually written iteration Your_tree_type::const_iterator end = tree end(); for (your_tree_type::const_iterator it = tree begin(); it != end; ++it)
- c++ - Boost 1. 46. 1, Property Tree: How to iterate through ptree . . .
The property tree iterators point to pairs of the form (key, tree) of type ptree::value_type The standard loop for iterating through the children of the node at path therefore looks like: BOOST_FOREACH(const ptree::value_type v, pt get_child(path)) { v first is the name of the child
- How are attributes parsed in Boost. PropertyTree?
Getting boost property_tree parent node 1 boost property_tree issues getting values
- c++ - Reading JSON with Boost property_tree - Stack Overflow
I've also added code to print the whole tree recursively so you can see how the JSON gets translated to the ptree Arrays elements are stored as key value pairs where the key is an empty string Share
- How to iterate over XML structure in boost::property_tree
Which is being read into a boost::property_tree, There are 1 Many <SomeElement>s, and then at an arbitrary depth within that element there could be 1 Many <ElementIWant>s Is there a way to iterate over the <ElementIWant> directly (in a single loop) in the order that they appear in the doc? I have looked at equal_range
- c++ - boost propertytree - Stack Overflow
) that property tree is not ordered by key "It is very important to remember that the property sequence is not ordered by the key It preserves the order of insertion " In that case I cannot imagine that elements inside the range will all have the requested key –
- Writing and Reading boost Property Tree From To File?
I want to write a boost::property_tree::ptree binary to a file, and read it out again into a ptree Since i´m not very comfort with the ptree and binary writing reading them I thought you guys can lead me into the right direction
- Dividing fences and other boundary issues | Legal Aid WA
Unless the tree is protected by a tree preservation order, you are allowed to: cut an overhanging branch back to the point where it enters your property dig up the root and cut a tree root back to the boundary or fence line of your property You should take care not to cause unnecessary damage to the tree
