- Method Detail
  - parameterName
```
public final String parameterName()
```
    The name of the parameter.
    
    Returns:
    
    The name of the parameter.
  - parameterValue
```
public final String parameterValue()
```
    The value of the parameter.
    
    Returns:
    
    The value of the parameter.
  - description
```
public final String description()
```
    Provides a description of the parameter.
    
    Returns:
    
    Provides a description of the parameter.
  - source
```
public final String source()
```
    The source of the parameter value.
    
    Returns:
    
    The source of the parameter value.
  - applyType
```
public final String applyType()
```
    Specifies the engine specific parameters type.
    
    Returns:
    
    Specifies the engine specific parameters type.
  - dataType
```
public final String dataType()
```
    Specifies the valid data type for the parameter.
    
    Returns:
    
    Specifies the valid data type for the parameter.
  - allowedValues
```
public final String allowedValues()
```
    Specifies the valid range of values for the parameter.
    
    Returns:
    
    Specifies the valid range of values for the parameter.
  - isModifiable
```
public final Boolean isModifiable()
```
    Indicates whether (true) or not (false) the parameter can be modified. Some parameters have security or operational implications that prevent them from being changed.
    
    Returns:
    
    Indicates whether (true) or not (false) the parameter can be modified. Some parameters have security or operational implications that prevent them from being changed.
  - minimumEngineVersion
```
public final String minimumEngineVersion()
```
    The earliest engine version to which the parameter can apply.
    
    Returns:
    
    The earliest engine version to which the parameter can apply.
  - applyMethod
```
public final ApplyMethod applyMethod()
```
    Indicates when to apply parameter updates.
    
    If the service returns an enum value that is not available in the current SDK version, applyMethod will return ApplyMethod.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from applyMethodAsString().
    
    Returns:
    
    Indicates when to apply parameter updates.
    
    See Also:
    
    ApplyMethod
  - applyMethodAsString
```
public final String applyMethodAsString()
```
    Indicates when to apply parameter updates.
    
    If the service returns an enum value that is not available in the current SDK version, applyMethod will return ApplyMethod.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from applyMethodAsString().
    
    Returns:
    
    Indicates when to apply parameter updates.

  - hasSupportedEngineModes
```
public final boolean hasSupportedEngineModes()
```
    For responses, this returns true if the service returned a value for the SupportedEngineModes 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.
  - supportedEngineModes
```
public final List<String> supportedEngineModes()
```
    The valid DB engine modes.
    
    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 hasSupportedEngineModes() method.
    
    Returns:
    
    The valid DB engine modes.

```
    Specified by:
