What is this Hash-like/Tree-like Construct Called?
- by viatropos
I want to create a "Config" class that acts somewhere between a hash and a tree. It's just for storing global values, which can have a context.
Here's how I use it:
Config.get("root.parent.child_b") #=> "value"
Here's what the class might look like:
class Construct
def get(path)
# split path by "."
# search tree for nodes
end
def set(key, value)
# split path by "."
# create tree node if necessary
# set tree value
end
def tree
{
:root => {
:parent => {
:child_a => "value",
:child_b => "another value"
},
:another_parent => {
:something => {
:nesting => "goes on and on"
}
}
}
}
end
end
Is there a name for this kind of thing, somewhere between Hash and Tree (not a Computer Science major)? Basically a hash-like interface to a tree.
