Method Detail

clone

public java.lang.Object clone()

Returns a deep copy of this Function instance

Specified by:

clone in class Program

Returns:

deep copy of this function

countNodes

public int countNodes()

Returns the number of nodes this function has.

Specified by:

countNodes in class Program

Returns:

number of children nodes

countProgramNodes

public int countProgramNodes()

Returns the number of program nodes this function has. This method traverses all the children nodes recursively until the leaf nodes are reached and counts the number of programs.

Specified by:

countProgramNodes in class Program

Returns:

number of program nodes

countFunctionNodes

public int countFunctionNodes()

Returns the number of function nodes this function has. This method traverses all the children nodes recursively until the leaf nodes are reached and counts the number of functions.

Specified by:

countFunctionNodes in class Program

Returns:

number of function nodes

toText

public java.lang.String toText()

Returns a string representation of this function. (Instead of toString - Used by Javolution)

Specified by:

toText in class Program

Returns:

string representation of this function
