- Method Detail
  - hasProperties
```
public final boolean hasProperties()
```
    For responses, this returns true if the service returned a value for the Properties 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.
  - properties
```
public final List<KeyValue> properties()
```
    A list of Java properties that are set when the step runs. You can use these properties to pass key-value pairs to your main function.
    
    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 hasProperties() method.
    
    Returns:
    
    A list of Java properties that are set when the step runs. You can use these properties to pass key-value pairs to your main function.
  - jar
```
public final String jar()
```
    A path to a JAR file run during the step.
    
    Returns:
    
    A path to a JAR file run during the step.
  - mainClass
```
public final String mainClass()
```
    The name of the main class in the specified Java file. If not specified, the JAR file should specify a Main-Class in its manifest file.
    
    Returns:
    
    The name of the main class in the specified Java file. If not specified, the JAR file should specify a Main-Class in its manifest file.
  - 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()
```
    A list of command line arguments passed to the JAR file's main function when executed.
    
    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:
    
    A list of command line arguments passed to the JAR file's main function when executed.
  - toBuilder

```
    Specified by:
    
    equalsBySdkFields in interface SdkPojo
  - toString
```
public final String 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
```
