Throws:

InvalidConfigurationException

Since:

1.1 (previously part of class Configuration)

addAll

public void addAll(java.util.Collection a_c)
            throws InvalidConfigurationException

Parameters:

a_c - Collection to add all elements from

size

public int size()

Returns:

number of selectors in list

Since:

isEmpty

public boolean isEmpty()

Returns:

true if number of selectors is zero

Since:

1.1

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object a_obj)

Overrides:

equals in class java.lang.Object

Parameters:

a_obj - Object

Returns:

boolean

Since:

1.1

get

public NaturalSelector get(int a_index)

Returns a Selector with specific index in the list.

Parameters:

a_index - the index of the Selector to read from the list

Specified by:

clone in interface ICloneable

Overrides:

clone in class java.lang.Object

Returns:

deep clone of this instance

Since:

compareTo

public int compareTo(java.lang.Object a_other)

The compareTo-method. Here we simply compare the class names of the contained selectors as INaturalSelector does not contain interface Comparable.
