newtype CollectionWithDeepEquality Source
See NodeWithDeepEquality
.
An SGF game tree node. Unlike in the SGF spec, we represent a game tree with nodes uniformly, rather than having the separation between sequences and nodes.

newtype NodeWithDeepEquality Source
A wrapper around Node
with an Eq
instance that considers two nodes
equal iff they contain the same properties (not necessarily in the same
order), and if they contain children (in the same order) whose nodes are
recursively equal.
This instance is not on Node
directly because it is not the only obvious
sense of equality (only comparing properties would be another one), and it's
also potentially expensive.
findProperty :: Descriptor a => a -> Node -> Maybe PropertySource
Searches for a matching property in a node's property list.
findProperty' :: Descriptor a => a -> [Property] -> Maybe PropertySource
Searches for a matching property in a property list.
findPropertyValue :: ValuedDescriptor a v => a -> Node -> Maybe vSource
Retrieves the value of a property in a node's property list.
findPropertyValue' :: ValuedDescriptor a v => a -> [Property] -> Maybe vSource
Retrieves the value of a property in a property list.
addProperty :: Property -> Node -> NodeSource
Appends a property to a node's property list.
addChild :: Node -> Node -> NodeSource
addChild child parent
appends a child node to a node's child list.
addChildAt :: Int -> Node -> Node -> NodeSource
addChildAt index child parent
inserts a child node into a node's child
list at the given index, shifting all nodes at or after the given index to
the right. The index must be in the range [0, numberOfChildren]
.
validateNode :: Bool -> Bool -> Node -> [String]Source
Returns a list of validation errors for the current node, an empty list if no errors are detected.
