=> the value at ‘/k/e/y/s or ‘default‘
Returns the value at ‘keys or, if it is not found, ‘default‘.
Returns an empty tree of type ‘<alist-treedb>‘.
=> children of node ‘/k/e/y/s‘
Returns a list of keys, which are the children of the given node.
<alist-treedb>) &rest keys) ¶=> the deleted value
Deletes the value at ‘/k/e/y/s‘.
<alist-treedb>) &rest keys) ¶=> ‘t‘ or ‘nil‘
Tests, if ‘/k/e/y/s‘ is a leaf in ‘db‘.
<alist-treedb>) &rest keys) ¶=> (the value at ‘/k/e/y/s‘, ‘t‘ / ‘nil‘) Returns the value of a leaf node as the first and ‘t‘ or ‘nil‘ as the second value, depending on if the node was found or not. Can be used with ‘setf‘.
<alist-treedb>) &rest keys) ¶=> ‘val‘
Sets the value at ‘/k/e/y/s‘ to ‘val‘.
<alist-treedb>) &rest keys) ¶=> ‘t‘ or ‘nil‘
Tests, if ‘/k/e/y/s‘ is a node in ‘db‘.
<alist-treedb>) &rest keys) ¶=> subtree at ‘/k/e/y/s‘
Returns a new tree object with the contents of the subtree.
The new object has the same type as ‘db‘.
<alist-treedb>) &rest keys) ¶=> a nested alist
Returns the tree in alist form
<alist-treedb>)) ¶=> a json string or ‘nil‘
Serializes the tree into json objects.
If ‘stream‘ is supplied, the json object is written to the corresponding stream.
Otherwise it is returned as a string.
<alist-treedb>) &optional stream) ¶<alist-treedb>)) ¶automatically generated reader method
root.
<alist-treedb>)) ¶automatically generated writer method
root.
Signaled, if an internal error occurs. Probably means, you found a bug.
