Method Detail

parseInt

public static int parseInt(java.lang.String text,
                           java.lang.String message,
                           org.xml.sax.Locator locator)
                    throws org.xml.sax.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:

org.xml.sax.SAXException - if there is a problem with the parsing.

parseInt

public static int parseInt(java.lang.String text,
                           java.lang.String message)
                    throws org.xml.sax.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:

org.xml.sax.SAXException - if there is a problem with the parsing.

parseInt

public static int parseInt(java.lang.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(java.lang.String text,
                               java.lang.String message,
                               org.xml.sax.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(java.lang.String text,
                               java.lang.String message)
                        throws org.xml.sax.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:

org.xml.sax.SAXException - if there is a problem with the parsing.

parseFloat

public static float parseFloat(java.lang.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(java.lang.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 java.lang.Boolean parseBoolean(java.lang.String value,
                                             org.xml.sax.Locator locator)
