appendIndex, compare, copy, down, free, isAncestor, isDescendant, next, prependIndex, prev, toString, up.
Getters
Setters
None.
appendIndex
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> Int32 |
|
| -> m () |
Appends a new index to a path.
As a result, the depth of the path is increased.
compare
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> TreePath |
|
| -> m Int32 | Returns: the relative positions of |
Compares two paths.
If a appears before b in a tree, then -1 is returned.
If b appears before a, then 1 is returned.
If the two nodes are equal, then 0 is returned.
copy
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> m TreePath | Returns: a new |
Creates a new TreePath-struct as a copy of path.
down
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> m () |
Moves path to point to the first child of the current path.
free
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> m () |
Frees path. If path is Nothing, it simply returns.
getDepth
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> m Int32 | Returns: The depth of |
Returns the current depth of path.
getIndices
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> m (Maybe [Int32]) | Returns: The current
indices, or |
Returns the current indices of path.
This is an array of integers, each representing a node in a tree. It also returns the number of elements in the array. The array should not be freed.
Since: 3.0
isAncestor
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> TreePath |
|
| -> m Bool | Returns: |
Returns True if descendant is a descendant of path.
isDescendant
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> TreePath |
|
| -> m Bool | Returns: |
Returns True if path is a descendant of ancestor.
new
Arguments
| :: (HasCallStack, MonadIO m) | |
| => m TreePath | Returns: A newly created |
Creates a new TreePath-struct.
This refers to a row.
newFirst
Arguments
| :: (HasCallStack, MonadIO m) | |
| => m TreePath | Returns: A new |
Creates a new TreePath-struct.
The string representation of this path is “0”.
newFromIndices
treePathNewFromIndices Source #
Arguments
| :: (HasCallStack, MonadIO m) | |
| => [Int32] |
|
| -> m TreePath | Returns: A newly created |
Creates a new path with the given indices array of length.
Since: 3.12
newFromString
treePathNewFromString Source #
Arguments
| :: (HasCallStack, MonadIO m) | |
| => Text |
|
| -> m TreePath |
Creates a new TreePath-struct initialized to path.
path is expected to be a colon separated list of numbers.
For example, the string “10:4:0” would create a path of depth
3 pointing to the 11th child of the root node, the 5th
child of that 11th child, and the 1st child of that 5th child.
If an invalid path string is passed in, Nothing is returned.
next
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> m () |
Moves the path to point to the next node at the current depth.
prependIndex
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> Int32 |
|
| -> m () |
Prepends a new index to a path.
As a result, the depth of the path is increased.
prev
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> m Bool | Returns: |
Moves the path to point to the previous node at the
current depth, if it exists.
toString
Arguments
| :: (HasCallStack, MonadIO m) | |
| => TreePath |
|
| -> m Text | Returns: A newly-allocated string.
Must be freed with |
Generates a string representation of the path.
This string is a “:” separated list of numbers. For example, “4:10:0:3” would be an acceptable return value for this string.
