Method Detail

parseString

public static String parseString(com.google.protobuf.Value rawValue)

Tries to parse a Value to a String representation.

Parameters:

rawValue - the value to parse

Returns:

the string representation

parseDouble

public static double parseDouble(com.google.protobuf.Value rawValue)
                          throws NumberFormatException

Tries to parse a Value to a double. If the Value has a numeric or string representation the parsing will succeed as long as the Value is within the Double range. Will throw a NumberFormatException if parsing is unsuccessful.

Parameters:

rawValue - the value to parse

Returns:

the double representation

Throws:

NumberFormatException

parseLong

public static long parseLong(com.google.protobuf.Value rawValue)
                      throws NumberFormatException

Tries to parse a Value to a long. If the Value has a numeric or string representation the parsing will succeed as long as the Value is within the long range. Will throw a NumberFormatException if parsing is unsuccessful.

Parameters:

rawValue - the value to parse

Returns:

the long representation

Throws:

NumberFormatException

parseBoolean

public static boolean parseBoolean(com.google.protobuf.Value rawValue)
                            throws Exception

Tries to parse a Value to a Boolean. If the Value has a boolean, numeric or string representation the parsing will succeed. A bool Value representation is parsed directly. A String Value representation returns true if the string argument is not null and equal to, ignoring case, the string "true". A numeric Value representation returns true if the number equals "1". Will throw an Exception if parsing is unsuccessful.

Parameters:

rawValue - the value to parse

Returns:

the boolean representation

Throws:

Exception
