Package org.yamcs.parameter

Class ParameterValueList

java.lang.Object

org.yamcs.parameter.ParameterValueList

All Implemented Interfaces:

Iterable<ParameterValue>, Collection<ParameterValue>

public class ParameterValueList
extends Object
implements Collection<ParameterValue>

Stores a collection of ParameterValue indexed on Parameter

it works like a LinkedHashMap<Parameter, LinkedList<ParameterValue>>

it also works like a LinkedList<ParameterValue;>

Not thread safe

Field Details

EMPTY

public static final ParameterValueList EMPTY

Constructor Details

ParameterValueList

public ParameterValueList()

ParameterValueList

public ParameterValueList(Collection<ParameterValue> pvs)

Parameters:

pvs -

Method Details

add

public boolean add(ParameterValue pv)

Specified by:

add in interface Collection<ParameterValue>

count

public int count(Parameter p)

Return the number of values for p

Parameters:

p -

Returns:

getFirst

public ParameterValue getFirst()

getLast

public ParameterValue getLast()

getSize

public int getSize()

getLastInserted

public ParameterValue getLastInserted(Parameter p)

Returns the last inserted value for Parameter p or null if there is no value

Parameters:

p -

Returns:

getFirstInserted

public ParameterValue getFirstInserted(Parameter p)

Returns first inserted parameter value for the given parameter or null if there is none

Parameters:

p -

Returns:

get

public ParameterValue get(Parameter p,
 int n)

Returns the n'th instance of the parameter or null if it does not exist

If n = 0 it is equivalent with getFirstInserted(Parameter)

getFromEnd

public ParameterValue getFromEnd(Parameter p,
 int n)

Returns the n'th instance of the parameter from the end or null if it does not exist

If n = 0 it is equivalent with getLastInserted(Parameter)

forEach

public void forEach(Parameter p,
 Consumer<ParameterValue> action)

Performs the given action for each value of the parameter p The values are considered in insertion order - oldest is first to be processed

Parameters:

p -

action -

removeLast

public ParameterValue removeLast(Parameter p)

Remove the last inserted value for Parameter p

Parameters:

p -

Returns:

the value removed or null if there was no value for p

removeFirst

public ParameterValue removeFirst(Parameter p)

Remove the first inserted value for Parameter p

Parameters:

p -

Returns:

the value removed or null if there was no value for p

tailIterator

public Iterator<ParameterValue> tailIterator()

Creates an iterator which is positioned on the end of the list but returns all the elements added after the iterator has been created.

Removing elements will invalidate the iterator.

Returns:

iterator

public Iterator<ParameterValue> iterator()

Specified by:

iterator in interface Collection<ParameterValue>

Specified by:

iterator in interface Iterable<ParameterValue>

addAll

public boolean addAll(Collection<? extends ParameterValue> c)

Adds all element to this collection

Specified by:

addAll in interface Collection<ParameterValue>

Parameters:

c -

Returns:

clear

public void clear()

Throws UnsupportedOperationException

Specified by:

clear in interface Collection<ParameterValue>

contains

public boolean contains(Object o)

Return true if the list contains the exact same ParameterValue. That means exactly the same object.

Specified by:

contains in interface Collection<ParameterValue>

Parameters:

o -

Returns:

containsAll

public boolean containsAll(Collection<?> c)

Throws UnsupportedOperationException

Specified by:

containsAll in interface Collection<ParameterValue>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Collection<ParameterValue>

remove

public boolean remove(Object o)

Throws UnsupportedOperationException

Specified by:

remove in interface Collection<ParameterValue>

removeAll

public boolean removeAll(Collection<?> c)

Throws UnsupportedOperationException

Specified by:

removeAll in interface Collection<ParameterValue>

retainAll

public boolean retainAll(Collection<?> c)

Throws UnsupportedOperationException

Specified by:

retainAll in interface Collection<ParameterValue>

size

public int size()

Specified by:

size in interface Collection<ParameterValue>

toArray

public Object[] toArray()

Returns a copy of the list as array

Specified by:

toArray in interface Collection<ParameterValue>

toArray

public <T> T[] toArray(T[] a)

Throws UnsupportedOperationException

Specified by:

toArray in interface Collection<ParameterValue>

toString

public String toString()

Overrides:

toString in class Object

asList

public static ParameterValueList asList(ParameterValue... pvs)
