Method Detail

hasSkewedColumnNames

public final boolean hasSkewedColumnNames()

For responses, this returns true if the service returned a value for the SkewedColumnNames 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.

skewedColumnNames

public final List<String> skewedColumnNames()

A list of names of columns that contain skewed values.

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 hasSkewedColumnNames() method.

Returns:

A list of names of columns that contain skewed values.

hasSkewedColumnValues

public final boolean hasSkewedColumnValues()

For responses, this returns true if the service returned a value for the SkewedColumnValues 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.

skewedColumnValues

public final List<String> skewedColumnValues()

A list of values that appear so frequently as to be considered skewed.

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 hasSkewedColumnValues() method.

Returns:

A list of values that appear so frequently as to be considered skewed.

hasSkewedColumnValueLocationMaps

public final boolean hasSkewedColumnValueLocationMaps()

For responses, this returns true if the service returned a value for the SkewedColumnValueLocationMaps 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.

skewedColumnValueLocationMaps

public final Map<String,String> skewedColumnValueLocationMaps()

A mapping of skewed values to the columns that contain them.

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 hasSkewedColumnValueLocationMaps() method.

Returns:

A mapping of skewed values to the columns that contain them.
