AbstractDoubleValue

public AbstractDoubleValue()

Method Detail

getString

public String getString()

Description copied from interface: StringValue

Get the String representation of the current value.

NOTE: The value returned is not valid unless calling AnalyticsValue.exists() afterwards returns TRUE.

Specified by:

getString in interface StringValue

Returns:

the current value

getObject

public Object getObject()

Description copied from interface: AnalyticsValue

Get the object representation of the current value.

Specified by:

getObject in interface AnalyticsValue

Returns:

the current value

streamDoubles

public void streamDoubles(DoubleConsumer cons)

Description copied from interface: DoubleValueStream

Stream the double representations of all current values, if any exist.

Specified by:

streamDoubles in interface DoubleValueStream

Parameters:

cons - The consumer to accept the values

streamStrings

public void streamStrings(Consumer<String> cons)

Description copied from interface: StringValueStream

Stream the String representations of all current values, if any exist.

Specified by:

streamStrings in interface StringValueStream

Parameters:

cons - The consumer to accept the values

streamObjects

public void streamObjects(Consumer<Object> cons)

Description copied from interface: AnalyticsValueStream

Stream the object representations of all current values, if any exist.

Specified by:

streamObjects in interface AnalyticsValueStream

Parameters:

cons - The consumer to accept the values

convertToConstant

public AnalyticsValue convertToConstant()

Description copied from interface: AnalyticsValueStream

Converts this value to a ConstantValue if it's expression type is AnalyticsValueStream.ExpressionType.CONST.

If the value is reduced then no conversion will occur and the value itself will be returned.

Specified by:

convertToConstant in interface AnalyticsValueStream

Returns:

a constant representation of this value

getObjectComparator

public ExpressionComparator<Double> getObjectComparator(String expression)

Description copied from interface: ComparableValue

Create an entry comparator used to sort the facet-value buckets of a facet.

Specified by:

getObjectComparator in interface ComparableValue

Parameters:

expression - the name of the expression in the results array

Returns:

a comparator to sort the buckets with
