Method Details

alias
-
firstSource
The first data source to be included in the append operation.
- Returns:
- The first data source to be included in the append operation.
-
secondSource
The second data source to be appended to the first source.
- Returns:
- The second data source to be appended to the first source.
-
hasAppendedColumns
public final boolean hasAppendedColumns()For responses, this returns true if the service returned a value for the AppendedColumns property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()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. -
appendedColumns
The list of columns to include in the appended result, mapping columns from both sources.
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
hasAppendedColumns()method.- Returns:
- The list of columns to include in the appended result, mapping columns from both sources.

equalsBySdkFields
Description copied from interface:SdkPojoIndicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in anSdkPojoclass, and is generated based on a service model.If an
SdkPojoclass does not have any inherited fields,equalsBySdkFieldsandequalsare essentially the same.- Specified by:
equalsBySdkFieldsin interfaceSdkPojo- Parameters:
obj- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.
