Method Detail

size

public int size()

Specified by:

size in interface Collection<State>

Specified by:

size in interface List<State>

Specified by:

size in class AbstractCollection<State>

getIsReadOnly

public boolean getIsReadOnly()

Gets a value indicating whether or not the collection is read-only. This will be true for continuous variables.

getVariable

public Variable getVariable()

Gets the Variable this collection belongs to. This is null if this is a child state collection.

Returns:

The variable that owns this collection.

get

public State get(String name)

Performs a case sensitive lookup.

Parameters:

name - The name of the State to find.

Returns:

A State with the specified name if found; otherwise null.

get

public State get(String name,
                 boolean throwIfNotFound)

Performs a case sensitive lookup.

Parameters:

name - The name of the State to find.

throwIfNotFound - When true throws an exception if the name is not found.

Returns:

The State with the specified name; otherwise null.

findByValue

public State findByValue(Object value)

Finds the state whose value/> matches the given [value], or null if a match is not found. For discretized variables, each State.getValue() is an Interval, and this method returns the state whose interval contains the given [value].

Parameters:

value - The value to match to a State.getValue().

Returns:

The matching State or null if a match is not found.

get

public State get(int index)

Gets the State at the specified index.

Specified by:

get in interface List<State>

Specified by:

get in class AbstractList<State>

Returns:

The state.

set

public State set(int index,
                 State value)

Sets the State at the specified index.

Specified by:

set in interface List<State>

Overrides:

set in class AbstractList<State>

Parameters:

value - The state.

clear

public void clear()

Specified by:

clear in interface Collection<State>

Specified by:

clear in interface List<State>

Overrides:

clear in class AbstractList<State>

contains

public boolean contains(Object o)

Determines whether a State is in the collection. The operation is O(1).

Specified by:

contains in interface Collection<State>

Specified by:

contains in interface List<State>

Overrides:

contains in class AbstractCollection<State>

Parameters:

o - The State to locate in the collection. The value can be null.

Returns:

true if [o] is found in the collection; otherwise, false.

indexOf

public int indexOf(Object o)

Determines the index of a specific State in the collection. This operation is O(1).

Specified by:

indexOf in interface List<State>

Overrides:

indexOf in class AbstractList<State>

Parameters:

o - The state to find. The value can be null.

Returns:

The index of the state in the collection, or -1 if not found.

add

public void add(int index,
                State item)

Inserts an element into the collection at the specified index.

Specified by:

add in interface List<State>

Overrides:

add in class AbstractList<State>

Parameters:

index - The zero based index at which to add the element.

item - The item to insert. Cannot be null.

Throws:

NullPointerException - Raised when [item] is null.

IllegalStateException - Raised if the state already belongs to a network.

IllegalArgumentException - index is less than 0.-or-index is equal to or greater than the collection count.

remove

public State remove(int index)

Removes an element from the collection at the specified index.

Specified by:

remove in interface List<State>

Overrides:

remove in class AbstractList<State>

Parameters:

index - The zero based index at which to remove the element.

Throws:

IllegalArgumentException - index is less than 0.-or-index is equal to or greater than the collection count.
