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 data inputs identified by their node names.

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 data inputs identified by their node names.

joinType

public final JoinType joinType()

Specifies the type of join to be performed on the datasets.

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

Returns:

Specifies the type of join to be performed on the datasets.

JoinType

joinTypeAsString

public final String joinTypeAsString()

Specifies the type of join to be performed on the datasets.

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

Returns:

Specifies the type of join to be performed on the datasets.

See Also:

JoinType

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<JoinColumn> columns()

A list of the two columns to be joined.

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:

A list of the two columns to be joined.

toBuilder

public Join.Builder toBuilder()

Specified by:

toBuilder in interface ToCopyableBuilder<Join.Builder,Join>

builder

public static Join.Builder builder()

serializableBuilderClass

public static Class<? extends Join.Builder> serializableBuilderClass()

toString

Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.

Overrides:

toString in class Object

getValueForField

                                              Class<T> clazz)
