Method Detail

name

public final String name()

The name of the command.

Returns:

The name of the command.

scriptPath

public final String scriptPath()

The Amazon S3 location of the command script.

Returns:

The Amazon S3 location of the command script.

hasArgs

public final boolean hasArgs()

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

args

public final List<String> args()

Arguments for Amazon EMR to pass to the command for execution.

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 hasArgs() method.

Returns:

Arguments for Amazon EMR to pass to the command for execution.

Overrides:

                                              Class<T> clazz)
