HistogramAggregation

public HistogramAggregation(String id,
                            DocumentTypeField field)

Creates a new instance.

Parameters:

id - the aggregation identifier.

field - the field this histogram will be performed on.

Since:

11.0.0

Method Detail

getField

public DocumentTypeField getField()

Description copied from interface: IFieldAwareAggregation

Returns the field this aggregation is bound to.

Specified by:

getField in interface IFieldAwareAggregation

Returns:

the field this aggregation is bound to.

getInterval

public I getInterval()

Returns the interval.

Returns:

the interval

Since:

11.0.0

setInterval

public void setInterval(I interval)

Sets the interval.

Parameters:

interval - the interval value to set.

Since:

11.0.0

getOffset

public I getOffset()

Returns the offset.

Returns:

the offset

Since:

11.0.0

setOffset

public void setOffset(I offset)

Sets the offset.

Parameters:

offset - the offset value to set.

Since:

11.0.0

setExtendedBounds

public void setExtendedBounds(B lowerBound,
                              B upperBound)

Sets the extended bounds.
lowerBound and upperBound must be both not null or both null. When a histogram aggregation has a lower and upper bounds, the histogram will return buckets for the given limits, even if no documents fill a given interval bucket.

Parameters:

lowerBound - the lower limit.

upperBound - the upper limit.

Since:

11.0.0

getLowerBound

public B getLowerBound()

Returns the lowerBound.

Returns:

the lowerBound

Since:

11.0.0

getUpperBound

public B getUpperBound()

Returns the upperBound.

Returns:

the upperBound

Since:

11.0.0
