Constructor Summary

SliceNode()
Slice with defaults that do not impose a constraint (offset is ZERO, limit is Long.MAX_VALUE).

SliceNode(BOp[] args, Map<String,Object> anns)
Shallow copy constructor.

SliceNode(long offset, long limit)

SliceNode(SliceNode op)
Deep copy constructor.

Method Summary

long	getLimit()
long	getOffset()
boolean	hasSlice() Return true if the slice will impose a constraint ( offset GT ZERO or limit LT Long.MAX_VALUE).

SliceNode

public SliceNode()

Slice with defaults that do not impose a constraint (offset is ZERO, limit is Long.MAX_VALUE).

SliceNode

public SliceNode(long offset,
                 long limit)

Parameters:
