Class GrailsNameUtils

    java.lang.Object
      grails.util.GrailsNameUtils

    public class GrailsNameUtils

extends Object

Contains 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!

### getScriptName

    public static String getScriptName(Class clazz)

  Retrieves the script name representation of the supplied class. For example MyFunkyGrailsScript would be my-funky-grails-script

  Returns:
    The script name representation

### getScriptName

    public static String getScriptName(String name)

  Retrieves the script name representation of the given class name. For example MyFunkyGrailsScript would be my-funky-grails-script.

  Parameters:
    `name` - The class name to convert.
  Returns:
    The script name representation.

### getNameFromScript

    public static String getNameFromScript(String scriptName)

  Calculates the class name from a script name in the form my-funk-grails-script

    A class name

### getNaturalName

    public static String getNaturalName(String name)

  Converts a property name into its natural language equivalent eg ('firstName' becomes 'First Name')

  Parameters:
    `name` - The property name to convert
  Returns:
    The converted property name

### isBlank

    public static boolean isBlank(String str)

  Determines whether a given string is `null`, empty, or only contains whitespace. If it contains anything other than whitespace then the string is not considered to be blank and the method returns `false`.

  We could use Commons Lang for this, but we don't want GrailsNameUtils to have a dependency on any external library to minimise the number of dependencies required to bootstrap Grails.

  Parameters:
    `str` - The string to test.
  Returns:
    `true` if the string is `null`, or blank.
