Method Detail

setBulk
public void setBulk(long count)
Description copied from interface:Traverser.Admin
Set the number of traversers represented by this traverser.- Specified by:
setBulk
in interfaceTraverser.Admin<T>
- Overrides:
setBulk
in classAbstractTraverser<T>
- Parameters:
count
- the number of traversers
-
bulk
public long bulk()
Description copied from interface:Traverser
A traverser may represent a grouping of traversers to allow for more efficient data propagation.
-
merge
public void merge(Traverser.Admin<?> other)
Description copied from interface:Traverser.Admin
When two traversers are have equality with each other, then they can be merged. This method is used to merge the traversers into a single traverser. This is used for optimization where instead of enumerating all traversers, they can be counted.- Specified by:
merge
in interfaceTraverser.Admin<T>
- Overrides:
merge
in classO_Traverser<T>
- Parameters:
other
- the other traverser to merge into this traverser. Once merged, the other can be garbage collected.
-
getStepId
public String getStepId()
Description copied from interface:Traverser.Admin
Get the step id of where the traverser is located. This is typically used in multi-machine systems that require the movement of traversers between different traversal instances.- Specified by:
getStepId
in interfaceTraverser.Admin<T>
- Overrides:
getStepId
in classAbstractTraverser<T>
- Returns:
- The future step for the traverser
-
setStepId
public void setStepId(String stepId)
Description copied from interface:Traverser.Admin
Set the step id of where the traverser is located. If the future isTraverser.Admin.HALT
, thenTraverser.Admin.isHalted()
is true.- Specified by:
setStepId
in interfaceTraverser.Admin<T>
- Overrides:
setStepId
in classAbstractTraverser<T>
- Parameters:
stepId
- The future step of the traverser
-
hashCode
