## Class ClassName

- java.lang.Object
- - org.apache.geode.management.configuration.ClassName

- All Implemented Interfaces:
    Serializable

      public class ClassName
      extends Object
      implements Serializable

  Used to configure an attribute that represents an instance of a java class. If the class implements the org.apache.geode.cache.Declarable interface from the geode-core module then properties can also be configured that will be used to initialize the instance.

- - ### Field Summary

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `static ClassName` | `EMPTY` Can be used when updating an attribute to configure it with no class name.

  - ### Constructor Summary

    Constructors
    Constructor and Description
    `ClassName(String className)` Object to be instantiated using the empty param constructor of the className
    `ClassName(String className, Properties properties)`
    `ClassName(String className, String jsonInitProperties)` this is a convenient way to create a ClassName object using json represented properties

  - ### Method Summary

    All Methods Static Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `boolean` | `equals(Object o)`
    `String` | `getClassName()`
    `Properties` | `getInitProperties()`
    `int` | `hashCode()`
    `static boolean` | `isClassNameValid(String className)` this provides a convenient method to validate if the given name is a valid classname

- - ### Field Detail

    - #### EMPTY

          public static final ClassName EMPTY

      Can be used when updating an attribute to configure it with no class name.

  - ### Constructor Detail

    - #### ClassName

          public ClassName(String className)

      Object to be instantiated using the empty param constructor of the className
      Parameters:
        `className` - this class needs a no-arg constructor.

    - #### ClassName

          public ClassName(String className,
                           String jsonInitProperties)

      this is a convenient way to create a ClassName object using json represented properties
      Parameters:
        `className` - this class needs to have a no-arg constructor
        `jsonInitProperties` - a json representation of the initialization properties that will be passed to `org.apache.geode.cache.Declarable#initialize` in the geode-core module. If the className is not Declarable, then these properties will be ignored
      Throws:
        `IllegalArgumentException` - if the class name is not valid
        `IllegalArgumentException` - if jsonInitProperties is invalid JSON

    - #### ClassName

          public ClassName(String className,
                           Properties properties)

      Parameters:
        `className` - the name of the class to be instantiated. This class needs to have a no-arg constructor.
        `properties` - the initialization properties that will be passed to `org.apache.geode.cache.Declarable#initialize` in the geode-core module. If the className is not Declarable, then these properties will be ignored
      Throws:
        `IllegalArgumentException` - if classname contains illegal classname characters

  - ### Method Detail

    - #### getClassName

          public String getClassName()

      Returns:
        the name of the class

    - #### getInitProperties

          public Properties getInitProperties()

      Returns:
        the properties that will be used when an instance is created.

    - #### hashCode

          public int hashCode()

      Overrides:
        `hashCode` in class `Object`

    - #### equals

          public boolean equals(Object o)

      Overrides:
        `equals` in class `Object`

    - #### isClassNameValid

          public static boolean isClassNameValid(String className)

      this provides a convenient method to validate if the given name is a valid classname
      Returns:
        false if classname is blank or has invalid classname characters
