Class ParameterValueList

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractList<E>

java.util.AbstractSequentialList<ParameterValue>

org.yamcs.parameter.ParameterValueList

All Implemented Interfaces:

Iterable<ParameterValue>, Collection<ParameterValue>, List<ParameterValue>

public class ParameterValueList
extends AbstractSequentialList<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>

Specified by:

add in interface List<ParameterValue>

Overrides:

add in class AbstractList<ParameterValue>

count

public int count(org.yamcs.xtce.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(org.yamcs.xtce.Parameter p)

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

Parameters:

p -

Returns:

getFirstInserted

public ParameterValue getFirstInserted(org.yamcs.xtce.Parameter p)

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

Parameters:

p -

Returns:

get

public ParameterValue get(org.yamcs.xtce.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(org.yamcs.xtce.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(org.yamcs.xtce.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(org.yamcs.xtce.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(org.yamcs.xtce.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.
