Method Summary

Modifier and Type	Method	Description
ExponentialHistogramBlockBuilder	append(ExponentialHistogram histogram)
ExponentialHistogramBlockBuilder	appendNull()	Appends a null value to the block.
ExponentialHistogramBlockBuilder	beginPositionEntry()	Begins a multivalued entry.
ExponentialHistogramBlock	build()	Builds the block.
void	close()
ExponentialHistogramBlockBuilder	copyFrom(Block block, int beginInclusive, int endExclusive)	Copy the values in block from beginInclusive to endExclusive into this builder.
ExponentialHistogramBlock.Builder	copyFrom(ExponentialHistogramBlock block, int position)	Copy the values in block from the given positon into this builder.
void	deserializeAndAppend(ExponentialHistogramBlock.SerializedInput input)	Decodes and appends a value serialized with ExponentialHistogramBlock.serializeExponentialHistogram(int, ExponentialHistogramBlock.SerializedOutput, BytesRef).
BlockLoader.BytesRefBuilder	encodedHistograms()
ExponentialHistogramBlockBuilder	endPositionEntry()	Ends the current multi-value entry.
long	estimatedBytes()	An estimate of the number of bytes the Block created by Block.Builder.build() will use.
BlockLoader.DoubleBuilder	maxima()
BlockLoader.DoubleBuilder	minima()
ExponentialHistogramBlockBuilder	mvOrdering(Block.MvOrdering mvOrdering)	How are multivalued fields ordered? This defaults to Block.MvOrdering.UNORDERED but when you set it to Block.MvOrdering.DEDUPLICATED_AND_SORTED_ASCENDING some operators can optimize themselves.
BlockLoader.DoubleBuilder	sums()
BlockLoader.LongBuilder	valueCounts()
BlockLoader.DoubleBuilder	zeroThresholds()

Method Details

minima

public BlockLoader.DoubleBuilder minima()

Specified by:

minima in interface BlockLoader.ExponentialHistogramBuilder

maxima

public BlockLoader.DoubleBuilder maxima()

Specified by:

maxima in interface BlockLoader.ExponentialHistogramBuilder

sums

public BlockLoader.DoubleBuilder sums()

Specified by:

sums in interface BlockLoader.ExponentialHistogramBuilder

valueCounts

public BlockLoader.LongBuilder valueCounts()

Specified by:

valueCounts in interface BlockLoader.ExponentialHistogramBuilder

zeroThresholds

public BlockLoader.DoubleBuilder zeroThresholds()

Specified by:

zeroThresholds in interface BlockLoader.ExponentialHistogramBuilder

encodedHistograms

public BlockLoader.BytesRefBuilder encodedHistograms()

Specified by:

encodedHistograms in interface BlockLoader.ExponentialHistogramBuilder

append

public ExponentialHistogramBlockBuilder append(ExponentialHistogram histogram)

deserializeAndAppend

public void deserializeAndAppend(ExponentialHistogramBlock.SerializedInput input)

Decodes and appends a value serialized with ExponentialHistogramBlock.serializeExponentialHistogram(int, ExponentialHistogramBlock.SerializedOutput, BytesRef).

Parameters:

input - the input to deserialize from

build

public ExponentialHistogramBlock build()

Description copied from interface: Block.Builder

Builds the block. This method can be called multiple times.

Specified by:

build in interface Block.Builder

Specified by:

build in interface BlockLoader.Builder

Specified by:

build in interface ExponentialHistogramBlock.Builder

appendNull

public ExponentialHistogramBlockBuilder appendNull()

Description copied from interface: Block.Builder

Appends a null value to the block.

Specified by:

appendNull in interface Block.Builder

Specified by:

appendNull in interface BlockLoader.Builder

beginPositionEntry

public ExponentialHistogramBlockBuilder beginPositionEntry()

Description copied from interface: Block.Builder

Begins a multivalued entry. Calling this for the first time will put the builder into a mode that generates Blocks that return true from Block.mayHaveMultivaluedFields() which can force less optimized code paths. So don't call this unless you are sure you are emitting more than one value for this position.

Specified by:

beginPositionEntry in interface Block.Builder

Specified by:

beginPositionEntry in interface BlockLoader.Builder

endPositionEntry

public ExponentialHistogramBlockBuilder endPositionEntry()

Description copied from interface: Block.Builder

Ends the current multi-value entry.

Specified by:

endPositionEntry in interface Block.Builder

Specified by:

endPositionEntry in interface BlockLoader.Builder

copyFrom

public ExponentialHistogramBlockBuilder copyFrom(Block block,
 int beginInclusive,
 int endExclusive)

Description copied from interface: Block.Builder

Copy the values in block from beginInclusive to endExclusive into this builder.

For single position copies use the faster IntBlock.Builder.copyFrom(IntBlock, int), LongBlock.Builder.copyFrom(LongBlock, int), etc.

Specified by:

copyFrom in interface Block.Builder

copyFrom

public ExponentialHistogramBlock.Builder copyFrom(ExponentialHistogramBlock block,
 int position)

Description copied from interface: ExponentialHistogramBlock.Builder

Copy the values in block from the given positon into this builder.

Specified by:

copyFrom in interface ExponentialHistogramBlock.Builder

mvOrdering

public ExponentialHistogramBlockBuilder mvOrdering(Block.MvOrdering mvOrdering)

Description copied from interface: Block.Builder

How are multivalued fields ordered? This defaults to Block.MvOrdering.UNORDERED but when you set it to Block.MvOrdering.DEDUPLICATED_AND_SORTED_ASCENDING some operators can optimize themselves. This is a promise that is never checked. If you set this to anything other than Block.MvOrdering.UNORDERED be sure the values are in that order or other operators will make mistakes. The actual ordering isn't checked at runtime.

Specified by:

mvOrdering in interface Block.Builder

estimatedBytes

public long estimatedBytes()

Description copied from interface: Block.Builder

An estimate of the number of bytes the Block created by Block.Builder.build() will use. This may overestimate the size but shouldn't underestimate it.

Specified by:

estimatedBytes in interface Block.Builder

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface org.elasticsearch.core.Releasable
