grafeno.linearizers.node_edges module

class grafeno.linearizers.node_edges.Linearizer(node_header='', node_sep='n', edge_header='n', edge_sep='n', footer='', graph=None)

Bases: object

This linearizer outputs the nodes first, and then the edges.

Parameters:

node_header : string

A string to print before all other content.

node_sep : string

A string to print between nodes.

edge_header : string

A string to print after the nodes, and before the edges.

edge_sep : string

A string to print between edges.

footer : string

A string to print after all other content.

graph : Graph

The graph to linearize.

Attributes

graph

(Graph) The graph to linearize.

Methods

filter_edge(n, m, edge)

Override this method to exclude some edges from the output.

Parameters:

n : int

The id of the head of the edge

m : int

The id of the child of the edge

edge : dict

The grammatemes of the edge to filter.

Returns:

bool

Whether to include this edge in further processing.

filter_node(node)

Override this method to exclude some nodes from the output.

Parameters:

node : dict

The grammatemes of the node to filter.

Returns:

bool

Whether to include this node in further processing.

linearize()

process_edge(n, m, edge)

This method generates a string representation of an edge. Override to customize.

Parameters:

n : int

Id of the head node.

m : int

Id of the dependent node.

edge : dict

Grammatemes of the edge between `n’ and `m’.

Returns:

string

A string representation of the edge.

process_node(node)

This method generates a string representation of a node. Override to customize.

Parameters:

node : dict

The grammatemes of the node to transform.

Returns:

string

A string representation of the node.
