Class GraphWriter<V,E>

java.lang.Object
  bcds.phison.io.GraphWriter<V,E>

Direct Known Subclasses:

GraphMLWriter, SgfGraphWriter

public abstract class GraphWriter<V,E>
extends java.lang.Object

Base class for all topology file writers; it defines both an interface and useful methods and data for derived classes. For a SimGraph to be writable, its nodes must implement GraphIONode.

Constructor Summary

GraphWriter(java.lang.String fname, SimGraph<V,E> g)

GraphWriter(java.io.Writer wr, SimGraph<V,E> g)
Creates a GraphWriter for g and prepares a buffered writer around wr.

Method Summary

void	printf(java.lang.String fmt, java.lang.Object... args) Writes a formatted string to the output stream.
void	setCapacityMap(java.util.Map<E,java.lang.Integer> cap) Saves a reference to the capacity map that will be written out by writeAll().
void	setCostMap(java.util.Map<E,? extends java.lang.Number> cost) Saves a reference to the cost map that will be written out by writeAll().
void	setHeadingComment(java.lang.String comment) Sets a comment that is typically written at the beginning of the output file (for example, a time stamp).
void	setNetName(java.lang.String netname) Sets a name/identification of the topology to be written.
void	setTrafficMatrix(java.util.Map<SimplePair<V,V>,java.lang.Double> trf) Saves a reference to the traffic matrix that will be written out by writeAll().
void	write(java.lang.String netname, java.lang.String heading_comment, java.util.Map<E,java.lang.Integer> capacity_map, java.util.Map<E,? extends java.lang.Number> cost_map, java.util.Map<SimplePair<V,V>,java.lang.Double> trf) Calls the appropriate setters (setCapacityMap(), setCostMap(), etc.), and finally invokes writeAll().

Constructor Detail

GraphWriter

public GraphWriter(java.io.Writer wr,
                   SimGraph<V,E> g)

Creates a GraphWriter for g and prepares a buffered writer around wr.

GraphWriter

public GraphWriter(java.lang.String fname,
                   SimGraph<V,E> g)

Method Detail

write

public void write(java.lang.String netname,
                  java.lang.String heading_comment,
                  java.util.Map<E,java.lang.Integer> capacity_map,
                  java.util.Map<E,? extends java.lang.Number> cost_map,
                  java.util.Map<SimplePair<V,V>,java.lang.Double> trf)

Calls the appropriate setters (setCapacityMap(), setCostMap(), etc.), and finally invokes writeAll().

setNetName

public void setNetName(java.lang.String netname)

Sets a name/identification of the topology to be written. If never called, the netname is the empty string.

setHeadingComment

public void setHeadingComment(java.lang.String comment)

Sets a comment that is typically written at the beginning of the output file (for example, a time stamp). The contents of comment must be consistent with the format of the output.

setCostMap

public void setCostMap(java.util.Map<E,? extends java.lang.Number> cost)

Saves a reference to the cost map that will be written out by writeAll(). cost can be null.

setCapacityMap

public void setCapacityMap(java.util.Map<E,java.lang.Integer> cap)

Saves a reference to the capacity map that will be written out by writeAll().

setTrafficMatrix

public void setTrafficMatrix(java.util.Map<SimplePair<V,V>,java.lang.Double> trf)

Saves a reference to the traffic matrix that will be written out by writeAll(). trf can be null.

printf

public void printf(java.lang.String fmt,
                   java.lang.Object... args)

Writes a formatted string to the output stream.

Throws:

AnyException - wrapping an IOException if an IO error occurs.
