NameUtils (micronaut 2.0.0.BUILD-SNAPSHOT API)

java.lang.Object
- io.micronaut.cli.util.NameUtils

```
public final class NameUtils
extends Object
```
Utility methods for converting between different name types, for example from class names -> property names and vice-versa. The key aspect of this class is that it has no dependencies outside the JDK!

@Deprecated
public static boolean isGetter(String name,
                                           Class<?>[] args)
```
    Deprecated. use isGetter(String, Class, Class[]) instead because this method has a defect for "is.." method with Boolean return types.
    
    Returns true if the name of the method specified and the number of arguments make it a javabean property getter. The name is assumed to be a valid Java method name, that is not verified.
    
    Parameters:
    
    name - The name of the method
    
    args - The arguments
    
    Returns:
    
    true if it is a javabean property getter
  - isGetter
```
public static boolean isGetter(String name,
                               Class returnType,
                               Class<?>[] args)
```
    Returns true if the name of the method specified and the number of arguments make it a javabean property getter. The name is assumed to be a valid Java method name, that is not verified.
    
    Parameters:
    
    name - The name of the method
    
    returnType - The return type of the method
    
    args - The arguments
    
    Returns:
    
    true if it is a javabean property getter
  - isPropertyMethodSuffix
```
protected static boolean isPropertyMethodSuffix(String suffix)
```
    This method is used when interrogating a method name to determine if the method represents a property getter. For example, if a method is named getSomeProperty, the value "SomeProperty" could be passed to this method to determine that the method should be considered a property getter. Examples of suffixes that would be considered property getters:
    - SomeProperty
    - Word
    - aProperty
    - S
    - X567
    Examples of suffixes that would not be considered property getters:
    - someProperty
    - word
    - s
    - x567
    - 2other
    - 5
    A suffix like prop from a method getprop() is not recognized as a valid suffix. However Groovy will recognize such a method as a property getter but only if a method getProp() or a property prop does not also exist. The Java Beans specification is unclear on how to treat such method names, it only says that "by default" the suffix will start with a capital letter because of the camel case style usually used. (See the JavaBeans API specification sections 8.3 and 8.8.)
    This method assumes that all characters in the name are valid Java identifier letters.
    Parameters:
    
    suffix - The suffix to inspect
    
    Returns:
    
    true if suffix indicates a property name
  - getPropertyForSetter
```
public static String getPropertyForSetter(String setterName)
```
    Returns a property name equivalent for the given setter name or null if it is not a valid setter. If not null or empty the setter name is assumed to be a valid identifier.
    
    Parameters:
    
    setterName - The setter name, must be null or empty or a valid identifier name
    
    Returns:
    
    The property name equivalent
