defineResource

public void defineResource(Resource resource)

Defines resource and assigns a numeric id

Parameters:

resource - resource to manage

getAvailableResources

public int getAvailableResources(Resource resource)

Gets total number of available resources.

Parameters:

resource - resource to get the information for

Returns:

number of available resources. Returns Integer.MAX_VALUE if unlimited resources are available

getDefinedResource

public Resource getDefinedResource(String id)

Gets an resource by alphanumeric identifier
