class Cluster(Graph) |
| |
Class representing a cluster in Graphviz's dot language.
This class implements the methods to work on a representation
of a cluster in Graphviz's dot language.
cluster(graph_name='subG', suppress_disconnected=False, attribute=value, ...)
graph_name:
the cluster's name (the string 'cluster' will be always prepended)
suppress_disconnected:
defaults to false, which will remove from the
cluster any disconnected nodes.
All the attributes defined in the Graphviz dot language should
be supported.
Attributes can be set through the dynamically generated methods:
set_[attribute name], i.e. set_color, set_fontname
or using the instance's attributes:
Cluster.[attribute name], i.e.
cluster_instance.color, cluster_instance.fontname

Any subgraph added to a parent graph receives a reference
to the parent to access some common data.
- set_name(self, graph_name)
- Set the graph's name.
- set_simplify(self, simplify)
- Set whether to simplify or not.
If True it will avoid displaying equal edges, i.e.
only one edge between two nodes. removing the
duplicated ones.
- set_strict(self, val)
- Set graph to 'strict' mode.
This option is only valid for top level graphs.
- set_suppress_disconnected(self, val)
- Suppress disconnected nodes in the output graph.
This option will skip nodes in the graph with no incoming or outgoing
edges. This option works also for subgraphs and has effect only in the
current graph/subgraph.
- set_type(self, graph_type)
- Set the graph's type, 'graph' or 'digraph'.
- to_string(self)
- Returns a string representation of the graph in dot language.
It will return the graph and all its subelements in string from.
Data and other attributes inherited from Graph:
- __dict__ = <dictproxy object>
- dictionary for instance variables (if defined)
- __weakref__ = <attribute '__weakref__' of 'Graph' objects>
- list of weak references to the object (if defined)
Methods inherited from Common:
- char_range(self, a, b)
- Generate a list containing a range of characters.
Returns a list of characters starting from 'a' up to 'b'
both inclusive.
- is_ID(self, s)
- Checks whether a string is an dot language ID.
It will check whether the string is solely composed
by the characters allowed in an ID or not.
Data and other attributes inherited from Common:
- chars_ID = None
- parent_graph = None
