root :: Tree a -> aSource

rootUpd :: Tree a -> a -> Tree aSource

foot :: Tree (GNode a) -> GNode aSource

setLexeme :: [Text] -> Tree (GNode a) -> Tree (GNode a)Source

Given a lexical item l and a tree node n (actually a subtree with no children), return the same node with the lexical item as its unique child. The idea is that it converts terminal lexeme nodes into preterminal nodes where the actual terminal is the given lexical item

setAnchor :: FullList Text -> Tree (GNode a) -> Tree (GNode a)Source

Given a lexical item s and a Tree GNode t, returns the tree t' where l has been assigned to the anchor node in t'

lexemeAttributes :: [Text]Source

Attributes recognised as lexemes, in order of preference

crushTreeGNode :: Tree (GNode [GeniVal]) -> Maybe (Tree (GNode GeniVal))Source

data GNode gv Source

A single node of a TAG tree.

Constructors

GN
Fields gnname :: NodeName gup :: Flist gv top feature structure gdown :: Flist gv bottom feature structure ganchor :: Bool `False` for na nodes glexeme :: [Text] `[]` for na nodes gtype :: GType gaconstr :: Bool gorigin :: Text for TAG, this would be the elementary tree that this node originally came from

Instances

Loadable Macros
Eq gv => Eq (GNode gv)
Data gv => Data (GNode gv)
Binary gv => Binary (GNode gv)
NFData gv => NFData (GNode gv)	A single node of a TAG tree.
Pretty (GNode GeniVal)	The default show for GNode tries to be very compact; it only shows the value for cat attribute and any flags which are marked on that node. This is one the places where the pretty representation of a GenI object is different from its GenI-format one

DescendGeniVal v => DescendGeniVal (GNode v)
Collectable gv => Collectable (GNode gv)
