parseInt
Parses the stringtext
into an int. If text is null or does not contain a parsable value, the message given inmessage
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
Parses an integer.- Parameters:
text
- the text to parse.defaultVal
- the default value.- Returns:
- the integer.
-
parseFloat
Parses the stringtext
into an float. If text is null or does not contain a parsable value, the message given inmessage
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
Parses the stringtext
into an float. If text is null or does not contain a parsable value, the message given inmessage
is used to throw a SAXException.- Parameters:
text
- the text to parse.defaultVal
- the defaultValue returned if parsing fails.- Returns:
- the float value.
-
parseBoolean
Parses a boolean. If the stringtext
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.
-
parseString
Parses a string. If thetext
is null, defaultval is returned.- Parameters:
text
- the text to parse.defaultVal
- the default value.- Returns:
- a string.
-
parseStroke
Creates a basic stroke given the width contained as float in the given string. If the string could not be parsed into a float, a basic stroke with the width of 1 is returned.- Parameters:
weight
- a string containing a number (the stroke weight).- Returns:
- the stroke.
-
parseColor
Parses a color entry. If the entry is in hexadecimal or ocal notation, the color is created using Color.decode(). If the string denotes a constant name of on of the color constants defined in java.awt.Color, this constant is used.As fallback the color black is returned if no color can be parsed.
- Parameters:
color
- the color (as a string).- Returns:
- the paint.
-
parseColor
Parses a color entry. If the entry is in hexadecimal or octal notation, the color is created using Color.decode(). If the string denotes a constant name of one of the color constants defined in java.awt.Color, this constant is used.As fallback the supplied default value is returned if no color can be parsed.
- Parameters:
color
- the color (as a string).defaultValue
- the default value (returned if no color can be parsed).- Returns:
- the paint.
-
parseRelativeFloat
Parses a position of an element. If a relative postion is given, the returnvalue is a negative number between 0 and -100.- Parameters:
value
- the value.exceptionMessage
- the exception message.- Returns:
- the float value.
- Throws:
SAXException
- if there is a problem parsing the string.
-
getElementPosition
Parses an element position. The position is stored in the attributes "x", "y", "width" and "height". The attributes are allowed to have relative notion.- Parameters:
atts
- the attributes.- Returns:
- the element position.
- Throws:
SAXException
- if there is a problem getting the element position.
