Constructor Detail

XorAggregationResult

public XorAggregationResult()

Constructs an empty result node. NOTE: This instance is broken until non-optional member data is set.

XorAggregationResult

public XorAggregationResult(long xor)

Constructs an instance of this class with given xor value.

Parameters:

xor - The initial xor value to set.

Method Detail

getXor

public long getXor()

Returns the current xor value.

Returns:

The value.

setXor

public XorAggregationResult setXor(long xor)

Sets the current xor value.

Parameters:

xor - The value to set.

Returns:

This, to allow chaining.
