Method Detail

hasColumn

public final boolean hasColumn()

For responses, this returns true if the service returned a value for the Column property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

column

public final List<String> column()

Specifies the column on the data set on which the aggregation function will be applied.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasColumn() method.

Returns:

Specifies the column on the data set on which the aggregation function will be applied.

aggFunc

public final AggFunction aggFunc()

Specifies the aggregation function to apply.

Possible aggregation functions include: avg countDistinct, count, first, last, kurtosis, max, min, skewness, stddev_samp, stddev_pop, sum, sumDistinct, var_samp, var_pop

If the service returns an enum value that is not available in the current SDK version, aggFunc will return AggFunction.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from aggFuncAsString().

Returns:

Specifies the aggregation function to apply.

Possible aggregation functions include: avg countDistinct, count, first, last, kurtosis, max, min, skewness, stddev_samp, stddev_pop, sum, sumDistinct, var_samp, var_pop

aggFuncAsString

public final String aggFuncAsString()

Specifies the aggregation function to apply.

Possible aggregation functions include: avg countDistinct, count, first, last, kurtosis, max, min, skewness, stddev_samp, stddev_pop, sum, sumDistinct, var_samp, var_pop

If the service returns an enum value that is not available in the current SDK version, aggFunc will return AggFunction.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from aggFuncAsString().

Returns:

Specifies the aggregation function to apply.

Possible aggregation functions include: avg countDistinct, count, first, last, kurtosis, max, min, skewness, stddev_samp, stddev_pop, sum, sumDistinct, var_samp, var_pop
