## [Java] Class PluginDefaultGroovyMethods

- org.codehaus.groovy.vmplugin.v5.PluginDefaultGroovyMethods

- This class defines new Java 5 specific groovy methods which extend the normal JDK classes inside the Groovy environment. Static methods are used with the first parameter the destination class.

    Methods
    Type Params | Return Type | Name and description
    --- | --- | ---
    `` | `static StringBuilder` | `leftShift(StringBuilder self, Object value)` Overloads the left shift operator to provide an easy way to append multiple objects as string representations to a StringBuilder.
    `` | `static Object` | `next(Enum self)` This method is called by the ++ operator for enums.
    `` | `static String` | `plus(StringBuilder self, String value)` Appends a String to this StringBuilder.

- - ### Method Detail

    - #### public static StringBuilder leftShift(StringBuilder self, Object value)

      Overloads the left shift operator to provide an easy way to append multiple objects as string representations to a StringBuilder.

      Parameters:
        `self` - a StringBuilder
        `value` - a value to append
      Returns:
        the StringBuilder on which this operation was invoked

    - #### public static Object next(Enum self)

      This method is called by the ++ operator for enums. It will invoke Groovy's default next behaviour for enums do not have their own next method.

      Parameters:
        `self` - an Enum
      Returns:
        the next defined enum from the enum class

    - #### public static String plus(StringBuilder self, String value)

      Appends a String to this StringBuilder.

      Parameters:
        `self` - a StringBuilder
        `value` - a String
      Returns:
        a String

    - #### public static Object previous(Enum self)

      This method is called by the -- operator for enums. It will invoke Groovy's default previous behaviour for enums that do not have their own previous method.

      Parameters:
        `self` - an Enum
      Returns:
        the previous defined enum from the enum class

    - #### public static void putAt(StringBuilder self, IntRange range, Object value)

      Support the range subscript operator for StringBuilder. Index values are treated as characters within the builder.

      Parameters:
        `self` - a StringBuilder
        `range` - a Range
        `value` - the object that's toString() will be inserted

    - #### public static void putAt(StringBuilder self, EmptyRange range, Object value)

      Support the range subscript operator for StringBuilder.

      Parameters:
        `self` - a StringBuilder
        `range` - a Range
        `value` - the object that's toString() will be inserted

    - #### public static int size(StringBuilder builder)

      Standard Groovy size() method for StringBuilders.

      Parameters:
        `builder` - a StringBuilder
      Returns:
        the length of the StringBuilder
