Interface ISingleNodeValidator

All Known Implementing Classes:

SingleNodeValidator

public interface ISingleNodeValidator

Checks whether a single node is valid during GP program creation. This helps to avoid useless tries in program creation.

Since:

3.6

Field Summary

static java.lang.String

CVS_REVISION String containing the CVS revision.

Method Summary

boolean

isAllowed(int a_chromIndex, ProgramChromosome a_pc, CommandGene[] a_functionSet, CommandGene a_function, java.lang.Class a_returnType, int a_subReturnTyp, int a_index) Checks if the given a_function is allowed in the current context.

Method Detail

isAllowed

boolean isAllowed(int a_chromIndex,
                  ProgramChromosome a_pc,
                  CommandGene[] a_functionSet,
                  CommandGene a_function,
                  java.lang.Class a_returnType,
                  int a_subReturnTyp,
                  int a_index)

Checks if the given a_function is allowed in the current context.

Parameters:

a_chromIndex - index of the chromosome within the GP program

a_pc - the instance of the ProgramChromosome

a_functionSet - the current function set within the program chromosome (given as input parameter for convenience, could also be determined via a_pc.m_genes)

a_function - the function that should be added, if allowed

a_returnType - the class the return type is required to have

a_subReturnTyp - the sub return type the return type is required to have

a_index - the index of the up-to-date last command gene in the program chromosome

Returns:

true if a_function's class exists within a_functionSet
