Method Detail

writeEdgesToTab

public static String writeEdgesToTab(Set<Edge> edges)

Get a string representation of all edges in a collection, divided by newlines, with edges in a tabbed format.

Parameters:

edges - the edges that needs to be written

Returns:

a string representation of all edges in this network, ready for printing

writeToTab(be.svlandeg.diffany.core.networks.Edge)

writeToTab

public static String writeToTab(Edge e)

Get a string representation of an edge. More specifically, print it as: source.name - target.name - edge.type - symmetrical - weight - negated.

Parameters:

e - the edge

Returns:

a string representation of this edge, ready for printing

writeDefinitionToTab

public static String writeDefinitionToTab(EdgeDefinition def)

Get a string representation of an edge definition. More specifically, print it as: edge.type - symmetrical - weight - negated.

Parameters:

def - the original edge definition

Returns:

a string representation of this edge definition, ready for printing

getHeader

public static String getHeader()

Write the header line, i.e. a tab-delimited summary of the information that is printed with writeToTab.

Returns:

a tab-delimited string respresentation of edge data, useful as header in text files

readFromTab

public static Edge readFromTab(String s,
                               Map<String,Node> nodes)
                        throws IOException

Read an Edge from a tab-delimited String. A set of input nodes should be given as input and mapped by their unique ID, to be able to link the edge to the correct nodes.

Parameters:

s - the tab-delimited string containing all parameters of the Edge

nodes - the input nodes in the network, containing at least the two nodes for this edge (otherwise source/target will be null)

Returns:

the corresponding Edge object

Throws:

IOException - when an error occurs during parsing

readDefinitionFromTab

public static EdgeDefinition readDefinitionFromTab(String def)
                                            throws IOException

Read an EdgeDefinition from a tab-delimited String.

Parameters:

def - the original edge definition, in string format

Returns:

the edge definition represented by the input string

Throws:

IOException - when an error occurs during parsing
