boolean	equals(Object value, boolean includeTimestamp)
protected int	getField(int field)
PersistentFlavor<PackedHistoricalQualifiedValue>	getFlavor()	Retrieves the PersistentFlavor associated with this kind of persistent data.

DataQuality	getQuality()
TagPath	getSource()
Date	getTimestamp()
TimestampSource	getTimestampSource()
DataTypeClass	getTypeClass()
Object	getValue()
int	hashCode()	This hashCode function is implemented according to the same constraints as equals above

Method Details

equals

public boolean equals(Object value,
 boolean includeTimestamp)

getQuality

public DataQuality getQuality()

Specified by:

getQuality in interface HistoricalTagValue

getTimestamp

public Date getTimestamp()

Specified by:

getTimestamp in interface HistoricalTagValue

getValue

public Object getValue()

Specified by:

getValue in interface HistoricalTagValue

getFlavor

@Nonnull
public PersistentFlavor<PackedHistoricalQualifiedValue> getFlavor()

Description copied from interface: PersistentData

Retrieves the PersistentFlavor associated with this kind of persistent data.

Specified by:

getFlavor in interface PersistentData

Returns:

a PersistentFlavor object

getSource

public TagPath getSource()

Specified by:

getSource in interface HistoricalTagValue

getTypeClass

public DataTypeClass getTypeClass()

Specified by:

getTypeClass in interface HistoricalTagValue

getInterpolationMode

public InterpolationMode getInterpolationMode()

Specified by:

getInterpolationMode in interface HistoricalTagValue

getTimestampSource

public TimestampSource getTimestampSource()

getField

protected int getField(int field)

setField

protected void setField(int field,
 int value)

equals

public boolean equals(Object obj)

This is overridden in a particular way - we don't take value into account! This implementation is relied on to detect multiple values for a given time, which we can't have. If all other settings are equal, we only look at timestamp.

Overrides:

equals in class Object

hashCode

public int hashCode()

This hashCode function is implemented according to the same constraints as equals above

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
