Method Detail

parseInt

public static int parseInt(String text,
                           String message,
                           Locator locator)
                    throws SAXException

Parses the string text into an int. If text is null or does not contain a parsable value, the message given in message is used to throw a SAXException.

Parameters:

text - the text to parse.

message - the error message if parsing fails.

locator - the SAX locator to print meaningfull error messages.

Returns:

the int value.

Throws:

SAXException - if there is a problem with the parsing.

parseInt

public static int parseInt(String text,
                           String message)
                    throws SAXException

Parses the string text into an int. If text is null or does not contain a parsable value, the message given in message is used to throw a SAXException.

Parameters:

text - the text to parse.

message - the error message if parsing fails.

Returns:

the int value.

Throws:

SAXException - if there is a problem with the parsing.

parseInt

public static int parseInt(String text,
                           int defaultVal)

Parses an integer.

Parameters:

text - the text to parse.

defaultVal - the default value.

Returns:

the integer.

parseFloat

public static float parseFloat(String text,
                               String message,
                               Locator locator)
                        throws ParseException

Parses the string text into an float. If text is null or does not contain a parsable value, the message given in message is used to throw a SAXException.

Parameters:

text - the text to parse.

message - the error message if parsing fails.

locator - the SAX locator to print meaningfull error messages.

Returns:

the float value.

Throws:

ParseException - if the text is no valid float number.

parseFloat

public static float parseFloat(String text,
                               String message)
                        throws SAXException

Parses the string text into an float. If text is null or does not contain a parsable value, the message given in message is used to throw a SAXException.

Parameters:

text - the text to parse.

message - the error message if parsing fails.

Returns:

the float value.

Throws:

SAXException - if there is a problem with the parsing.

parseFloat

public static float parseFloat(String text,
                               float defaultVal)

Parses the string text into an float. If text is null or does not contain a parsable value, the message given in message is used to throw a SAXException.

Parameters:

text - the text to parse.

defaultVal - the defaultValue returned if parsing fails.

Returns:

the float value.

parseBoolean

public static boolean parseBoolean(String text,
                                   boolean defaultVal)

Parses a boolean. If the string text contains the value of "true", the true value is returned, else false is returned.

Parameters:

text - the text to parse.

defaultVal - the default value.

Returns:

a boolean.

parseBoolean

public static Boolean parseBoolean(String value,
                                   Locator locator)
                            throws ParseException

Translates an boolean string ("true" or "false") into the corresponding Boolean object.

Parameters:

value - the string that represents the boolean.

locator - the SAX locator to print meaningfull error messages.

Returns:

Boolean.TRUE or Boolean.FALSE

Throws:

ParseException - if an parse error occured or the string is not 'true' or 'false'.

parseString

public static String parseString(String text,
                                 String defaultVal)

Parses a string. If the text is null, defaultval is returned.

Parameters:

text - the text to parse.

defaultVal - the default value.

Returns:

a string.
