  • Method Details

    • charsetForName

      public final Charset charsetForName(String charsetName)
      Constructs a Charset for the given charset name. Implements the abstract method of super class.
      Specified by:
      charsetForName in class CharsetProvider
      Parameters:
      charsetName - charset name
      Returns:
      Charset object for the given charset name, null if unsupported

    • charsetForName

      public final Charset charsetForName(String charsetName, String classPath)
      Constructs a charset for the given ICU conversion table from the specified class path. Example use: cnv = CharsetProviderICU.charsetForName("myConverter", "com/myCompany/myDataPackage");. In this example myConverter.cnv would exist in the com/myCompany/myDataPackage Java package. Conversion tables can be made with ICU4C's makeconv tool. This function allows you to allows you to load user defined conversion tables that are outside of ICU's core data.
      Parameters:
      charsetName - The name of the charset conversion table.
      classPath - The class path that contain the conversion table.
      Returns:
      charset object for the given charset name, null if unsupported

    • charsetForName

      public Charset charsetForName(String charsetName, String classPath, ClassLoader loader)
      Constructs a charset for the given ICU conversion table from the specified class path. This function is similar to charsetForName(String, String).
      Parameters:
      charsetName - The name of the charset conversion table.
      classPath - The class path that contain the conversion table.
      loader - the class object from which to load the charset conversion table
      Returns:
      charset object for the given charset name, null if unsupported
