    • getString

      public static String getString(byte[] data, int offset, int length, String charset)
      Converts the byte array of HTTP content characters to a string. If the specified charset is not supported, default system encoding is used.
      Parameters:
      data - the byte array to be encoded
      offset - the index of the first byte to encode
      length - the number of bytes to encode
      charset - the desired character encoding
      Returns:
      The result of the conversion.
    • getString

      public static String getString(byte[] data, String charset)
      Converts the byte array of HTTP content characters to a string. If the specified charset is not supported, default system encoding is used.
      Parameters:
      data - the byte array to be encoded
      charset - the desired character encoding
      Returns:
      The result of the conversion.
    • getBytes

      public static byte[] getBytes(String data, String charset)
      Converts the specified string to a byte array. If the charset is not supported the default system charset is used.
      Parameters:
      data - the string to be encoded
      charset - the desired character encoding
      Returns:
      The resulting byte array.
    • getAsciiBytes

      public static byte[] getAsciiBytes(String data)
      Converts the specified string to byte array of ASCII characters.
      Parameters:
      data - the string to be encoded
      Returns:
      The string as a byte array.
    • getAsciiString

      public static String getAsciiString(byte[] data, int offset, int length)
      Converts the byte array of ASCII characters to a string. This method is to be used when decoding content of HTTP elements (such as response headers)
      Parameters:
      data - the byte array to be encoded
      offset - the index of the first byte to encode
      length - the number of bytes to encode
      Returns:
      The string representation of the byte array
    • getAsciiString

      public static String getAsciiString(byte[] data)
      Converts the byte array of ASCII characters to a string. This method is to be used when decoding content of HTTP elements (such as response headers)
      Parameters:
      data - the byte array to be encoded
      Returns:
      The string representation of the byte array
