public static boolean VERBOSE

Constructor Detail

BoidGraph

public BoidGraph()

New boids simulation represented as an interaction graph.

All parameters are set to defaults.

BoidGraph

public BoidGraph(String dgsConfig)
          throws IOException

New boids simulation represented as an interaction graph.

This pre-load a configuration from a DGS file.

Parameters:

dgsConfig - The initial configuration in DGS format.

Throws:

IOException - If the DGS cannot be read.

Method Detail

loadDGSConfiguration

public void loadDGSConfiguration(String dgs)
                          throws IOException

Load configuration from a dgs file or resource. See 'configExample.dgs' for an example of dgs configuration. The loader try to open the file first. If file is not found, loader try to get the resource using ClassLoader.getResourceAsStream(String).

Parameters:

dgs - path to the DGS file or resource containing the configuration.

Throws:

IOException - if something wrong happens with io.

loadDGSConfiguration

public void loadDGSConfiguration(InputStream in)
                          throws IOException

Load configuration from a dgs file. See 'configExample.dgs' for an example of dgs configuration.

Parameters:

in -

Throws:

IOException - if something wrong happens with io.

addDefaultSpecies

public BoidSpecies addDefaultSpecies()

Add a species with name "default" if does not yet exists.

Returns:

The created default species or the old one if it was already present.
