Method Detail

hasColumns

public final boolean hasColumns()

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

columns

public final List<GlueStudioSchemaColumn> columns()

Specifies the column definitions that make up a Glue schema.

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 hasColumns() method.

Returns:

Specifies the column definitions that make up a Glue schema.
