Method Detail

toString

public java.lang.String toString()

Description copied from class: GPNode

Returns a Lisp-like atom for the node which can be read in again by computer. If you need to encode an integer or a float or whatever for some reason (perhaps if it's an ERC), you should use the ec.util.Code library.

Overrides:

toString in class SemanticNode

expectedChildren

public int expectedChildren()

Description copied from class: GPNode

Returns the number of children this node expects to have. This method is only called by the default implementation of checkConstraints(...), and by default it returns CHILDREN_UNKNOWN. You can override this method to return a value >= 0, which will be checked for in the default checkConstraints(...), or you can leave this method alone and override checkConstraints(...) to check for more complex constraints as you see fit.

Overrides:

index

value
