Method Detail

name

public final String name()

The name of the transform node.

Returns:

The name of the transform node.

hasInputs

public final boolean hasInputs()

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

inputs

public final List<String> inputs()

The node ID inputs to the transform.

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 hasInputs() method.

Returns:

The node ID inputs to the transform.

unionType

public final UnionType unionType()

Indicates the type of Union transform.

Specify ALL to join all rows from data sources to the resulting DynamicFrame. The resulting union does not remove duplicate rows.

Specify DISTINCT to remove duplicate rows in the resulting DynamicFrame.

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

Returns:

Indicates the type of Union transform.

Specify ALL to join all rows from data sources to the resulting DynamicFrame. The resulting union does not remove duplicate rows.

Specify DISTINCT to remove duplicate rows in the resulting DynamicFrame.

unionTypeAsString

public final String unionTypeAsString()

Indicates the type of Union transform.

Specify ALL to join all rows from data sources to the resulting DynamicFrame. The resulting union does not remove duplicate rows.

Specify DISTINCT to remove duplicate rows in the resulting DynamicFrame.

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

Returns:

Indicates the type of Union transform.

Specify ALL to join all rows from data sources to the resulting DynamicFrame. The resulting union does not remove duplicate rows.

Specify DISTINCT to remove duplicate rows in the resulting DynamicFrame.
