Class AuxPoint

java.lang.Object

fact.auxservice.AuxPoint

All Implemented Interfaces:

Comparable<AuxPoint>

public class AuxPoint
extends Object
implements Comparable<AuxPoint>

This is a class to create immutable container holding data from some source providing auxiliary data. This can be a file or a database. The key passed to the getters has to be known beforehand of course. Created by kai on 31.03.15.

AuxPoint

public AuxPoint(ZonedDateTime timeStamp)

AuxPoint

public AuxPoint(ZonedDateTime timeStamp,
                Map<String,Serializable> data)

Creates an AuxPoint from a Timestamp and a map containing key,value pairs as found in the slow control data.

Parameters:

timeStamp - the timestamp specifying when the auxiliary data was recorded.

data - a map containing the names and values from the .fits files as key values pairs.

Method Detail

getTimeStamp

public ZonedDateTime getTimeStamp()

The timestamp from when sensor recorded this AuxPoint.

Returns:

the timestamp for this point.

getData

Returns:

the value or null

getFloat

public Float getFloat(String key)

Returns the value for the key iff it exists and its a Float. Returns null otherwise.

Parameters:

key - the name of the aux data you want to access. e.g. the name of the column in the aux fits file

Returns:

the value or null

getInteger

public Integer getInteger(String key)

Returns the value for the key iff it exists and its an Integer. Returns null otherwise.

Parameters:

key - the name of the aux data you want to access. e.g. the name of the column in the aux fits file

Returns:

the value or null

getString

Returns:

the value or null

getIntegerArray

public int[] getIntegerArray(String key)

Returns the value for the key iff it exists and its an int[]. Returns null otherwise.

Parameters:

key - the name of the aux data you want to access. e.g. the name of the column in the aux fits file

Returns:

the value or null

getDoubleArray
