Constructor Detail

SliceNode

public SliceNode(SliceNode op)

Deep copy constructor.

SliceNode

public SliceNode(BOp[] args,
         Map<String,Object> anns)

Shallow copy constructor.

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:

offset - The offset (origin ZERO).

limit - The limit (use Long.MAX_VALUE if there is no limit).

Method Detail

setOffset

public void setOffset(long offset)

getOffset

public long getOffset()

setLimit

public void setLimit(long limit)

getLimit

public long getLimit()

hasSlice

public boolean hasSlice()

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

toString

public String toString(int indent)

Description copied from class: CoreBaseBOp

The contract of this method at this level is under-specified. Sub-classes may choose between: - return a string representation of the object, similar to the use of CoreBaseBOp.toString() Or: - return a pretty-print representation of the object with indent Note that the former contract may or may not include recursive descent through a tree-like object, whereas the latter almost certainly does.
