DiscontinuityInterval

public DiscontinuityInterval(long startTime,
                             long endTime)

Method Detail

isDiscontinuity

public boolean isDiscontinuity()

Description copied from interface: StreamInterval

Returns true if this interval represents a discontinuity in the data stream. Such an interval will have 0 elements.

Specified by:

isDiscontinuity in interface StreamInterval

getStartTime

public long getStartTime()

Description copied from interface: StreamInterval

Returns the starting time (inclusive) of this interval.

Specified by:

getStartTime in interface StreamInterval

Specified by:

getStartTime in interface Range

getEndTime

public long getEndTime()

Description copied from interface: StreamInterval

Returns the end time (exclusive) of this interval.

Specified by:

getEndTime in interface StreamInterval

Specified by:

getEndTime in interface Range

getTimespan

public long getTimespan()

Description copied from interface: StreamInterval

Returns StreamInterval.getEndTime() - StreamInterval.getStartTime().

Specified by:

getTimespan in interface StreamInterval

getNumElements

public int getNumElements()

Description copied from interface: StreamInterval

Returns the total number of elements (fields) in this interval, not including the timestamp.

Specified by:

getNumElements in interface StreamInterval

getValueAt

public java.lang.Object getValueAt(long time,
                                   int element)

Description copied from interface: StreamInterval

Samples the value at the given time between startTime (inclusive) and endTime (exclusive). The result of calling this method with a time less than startTime or greater than or equal to endTime is undefined. It may throw IllegalArgumentException, but is not guaranteed to.

Specified by:

getValueAt in interface StreamInterval

getAverageValue

public java.lang.Object getAverageValue(int element)

Description copied from interface: StreamInterval

Returns the average value for the element over this interval's time range. For non-numeric types, such as Boolean, this method returns the exact value.

Specified by:

getAverageValue in interface StreamInterval

getMaximumValue

public java.lang.Object getMaximumValue(int element)

Description copied from interface: StreamInterval

Returns the maximum value for the element over this interval's time range. For non-numeric types, such as Boolean, this method returns the exact value.

Specified by:

getMaximumValue in interface StreamInterval

getMinimumValue

public java.lang.Object getMinimumValue(int element)

Description copied from interface: StreamInterval

Returns the minimum value for the element over this interval's time range. For non-numeric types, such as Boolean, this method returns the exact value.

Specified by:

getMinimumValue in interface StreamInterval

getIntegral

public java.lang.Number getIntegral(int element)

Description copied from interface: StreamInterval

Returns the result of the definite integral between this interval's start and end times. For non-numeric ElementTypes (such as Boolean), or for ElementCodecs that do not represent continuous ranges (such as SampledAlgorithm) this method always returns null. For numeric ElementTypes, this method always returns a Number object of the appropriate type.
