Sales of car in a year

Growth of Population of country in last x years.

Method Detail

getMetricFunctionDescriptor

<T extends MetricFunctionDescriptor> T getMetricFunctionDescriptor()

Gets the metric descriptor.

Returns:

the metric descriptor or null if none exists.

getFunctionParamBinding

java.lang.String getFunctionParamBinding(java.lang.String paramName)

Get the attribute associated with this parameter.

Parameters:

paramName - function parameter to bind to.

Returns:

getUnitOfMeasurement

java.lang.String getUnitOfMeasurement()

Get unit of measurement.

Returns:

Unit of measurement

getDependencies

java.util.Collection<Measurement> getDependencies()

Return a collection of measurements which need to be computed before this measurement can be computed.

Measurements can be chained thus. If measurement A depends on measurement B and C then B and C will be evaluated before A.

Returns:

getDataType

DataType getDataType()

Get DataType of measurement

Returns:

DataType of measurement
