Class ValueProvider.RuntimeValueProvider<T>

• java.lang.Object
• • com.google.cloud.dataflow.sdk.options.ValueProvider.RuntimeValueProvider<T>

• All Implemented Interfaces:

  public static class ValueProvider.RuntimeValueProvider<T>
  extends Object
  implements ValueProvider<T>, Serializable

  ValueProvider.RuntimeValueProvider is an implementation of ValueProvider that allows for a value to be provided at execution time rather than at graph construction time.

  To enforce this contract, if there is no default, users must only call get() at execution time (after a call to Pipeline.run()), which will provide the value of optionsMap.
