OpBase - Base class for OPEAL operators; operators are any object with the "apply"
method, which does things to individuals or populations.
my $op = new OpBase; #Creates empty op, with rate
my $xmlStr=<<EOC;
<op name='Mutation' type='unary' rate='2'>
<param name='probability' value='0.5' />
</op>
EOC
my $ref = XMLin($xmlStr);
my $op = OpBase->fromXML( $ref ); #Takes a hash of parsed XML and turns it into an operator
print $op->asXML(); #print its back in XML shape
print $op->rate(); #application rate; relative number of times it must be applied
print "Yes" if $op->check( 'BinaryIndi' ); #Prints Yes, it can be applied to BinaryIndi
print $op->arity(); #Prints 1, number of operands it can be applied to
Base class for operators applied to Individuals and Populations and all the rest
Automatically define accesors for instance variables
Takes a hash with specific parameters for each subclass, creates the object, and leaves subclass-specific assignments to subclasses
Takes a definition in the shape <op></op> and turns it into an object, if it knows how to do it. The definition must have been processed using XML::Simple.
It parses the common part of the operator, and leaves specific parameters for the subclass via the ``set'' method.
Prints as XML, following the EvoSpec 0.2 XML specification. Should be called from derived classes, not by itself.
Gets or sets the rate of application of the operator
Check if the object the operator is applied to has the correct type
Returns the arity, ie, the number of individuals it can be applied to
Default method; does not do anything; it is there to avoid errors
