Class QueryableIndexCursorHolder.TimestampCheckingOffset

java.lang.Object

org.apache.druid.segment.data.Offset

org.apache.druid.segment.QueryableIndexCursorHolder.TimestampCheckingOffset

All Implemented Interfaces:

Cloneable, HotLoopCallee, ReadableOffset

Direct Known Subclasses:

QueryableIndexCursorHolder.AscendingTimestampCheckingOffset, QueryableIndexCursorHolder.DescendingTimestampCheckingOffset

Enclosing class:

QueryableIndexCursorHolder

public abstract static class QueryableIndexCursorHolder.TimestampCheckingOffset
extends Offset

Method Summary

Modifier and Type	Method	Description
Offset	clone()
ReadableOffset	getBaseReadableOffset()	Returns the same offset ("this") or a readable "view" of this offset, which always returns the same value from ReadableOffset.getOffset(), as this offset.
int	getOffset()
void	increment()	Move to next offset
void	inspectRuntimeShape(RuntimeShapeInspector inspector)	Implementations of this method should call inspector.visit() with all fields of this class, which meet two conditions: 1.
void	reset()	Resets the Offset to the position it was created or cloned with.
protected abstract boolean	timeInRange(long current)
boolean	withinBounds()	Check if current offset position is within the valid range

Method Details

getOffset

public int getOffset()

withinBounds

public boolean withinBounds()

Description copied from class: Offset

Check if current offset position is within the valid range

Specified by:

withinBounds in class Offset

reset

public void reset()

Description copied from class: Offset

Resets the Offset to the position it was created or cloned with.

Specified by:

reset in class Offset

getBaseReadableOffset

public ReadableOffset getBaseReadableOffset()

Description copied from class: Offset

Returns the same offset ("this") or a readable "view" of this offset, which always returns the same value from ReadableOffset.getOffset(), as this offset. This method is useful for "unwrapping" such offsets as FilteredOffset and reduce reference indirection, when only ReadableOffset API is needed.

Specified by:

getBaseReadableOffset in class Offset

timeInRange

protected abstract boolean timeInRange(long current)

increment

public void increment()

Description copied from class: Offset

Move to next offset

Specified by:

increment in class Offset

clone

public Offset clone()

Overrides:

clone in class Offset

inspectRuntimeShape

public void inspectRuntimeShape(RuntimeShapeInspector inspector)

Description copied from interface: HotLoopCallee

Implementations of this method should call inspector.visit() with all fields of this class, which meet two conditions: 1. They are used in methods of this class, annotated with CalledFromHotLoop 2. They are either: a. Nullable objects b. Instances of HotLoopCallee c. Objects, which don't always have a specific class in runtime. For example, a field of type Set could be HashSet or TreeSet in runtime, depending on how this instance (the instance on which inspectRuntimeShape() is called) is configured. d. ByteBuffer or similar objects, where byte order matters e. boolean flags, affecting branch taking f. Arrays of objects, meeting any of conditions a-e.
