Class KeyValueData

java.lang.Object

org.lsst.ccs.bus.data.KeyValueData

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

KeyValueDataList

public class KeyValueData
extends Object
implements Serializable

Generic Data class for Key-Value pairs. This class is meant to be used by CCS Agents to publish key-value pairs type information. Subclasses of this class will provide additional information when needed. For example KeyValueTimeData provides a timestamp for the key-value pair.

Constructor Detail

KeyValueData

public KeyValueData(String key,
                    Serializable value,
                    org.lsst.ccs.utilities.taitime.CCSTimeStamp ccsTimeStamp,
                    KeyValueData.KeyValueDataType type)

Build a KeyValueData object providing the name and the value for the key-value pair and the CCSTimeStamp in which this data was accumulated and their type. The type defines what client codes will do with the KeyValueData.

Parameters:

key - The String representing the key

value - The Object representing the value of the pair.

ccsTimeStamp - The CCSTimestamp for this KeyValueData.

type - The type for this KeyValueData

KeyValueData

public KeyValueData(String key,
                    Serializable value,
                    org.lsst.ccs.utilities.taitime.CCSTimeStamp ccsTimeStamp)

Build a KeyValueData object providing the name and the value for the key-value pair and the CCSTimeStamp in which this data was accumulated.

Parameters:

key - The String representing the key

value - The Object representing the value of the pair.

ccsTimeStamp - The CCSTimestamp for this KeyValueData.

KeyValueData

public KeyValueData(String key,
                    Serializable value)

Build a KeyValueData object providing the name and the value for the key-value pair. The timestamp is automatically assigned the time this object was created.

Parameters:

key - The String representing the key

value - The Object representing the value of the pair.
