Class DecimalSymbols

java.lang.Object

net.sf.saxon.trans.DecimalSymbols

public class DecimalSymbols
extends Object

This class is modelled on Java's DecimalFormatSymbols, but it allows the use of any Unicode character to represent symbols such as the decimal point and the grouping separator, whereas DecimalFormatSymbols restricts these to a char (1-65535).

Set the character to be used as the decimal separator

Parameters:

value - the character to be used

Throws:

XPathException - if the value is not a single Unicode character (a surrogate pair is permitted)

                          throws XPathException

Set the character to be used as the grouping separator

Parameters:

value - the character to be used

Throws:

XPathException - if the value is not a single Unicode character (a surrogate pair is permitted)

setDigit

public void setDigit(String value)
              throws XPathException

Set the character to be used as the digit symbol (default is '#')

Parameters:

value - the character to be used

Throws:

XPathException - if the value is not a single Unicode character (a surrogate pair is permitted)

setMinusSign

public void setMinusSign(String value)
                  throws XPathException

setPercent

public void setPercent(String value)
                throws XPathException

Set the character to be used as the percent sign

Parameters:

Throws:

XPathException - if the value is not a single Unicode character (a surrogate pair is permitted), or if it is not a character classified in Unicode as a digit with numeric value zero

setExponentSeparator

public void setExponentSeparator(String value)
                          throws XPathException

Set the character to be used as the exponent separator

Parameters:

value - the character to be used

Throws:

XPathException - if the value is not a single Unicode character (a surrogate pair is permitted)

setPatternSeparator

public void setPatternSeparator(String value)
                         throws XPathException

Set the character to be used as the pattern separator (default ';')

Parameters:

setInfinity

public void setInfinity(String value)
                 throws XPathException

Set the string to be used to represent infinity

Parameters:

value - the string to be used

Throws:

XPathException - - should not happen

setNaN

value - the value of the property as a string (in many cases, this must be a single character)

precedence - the precedence of the property value

Throws:

XPathException - if the property is invalid. This method does not check the consistency of different properties. If two different values are supplied for the same property at the same precedence, the method does not complain, but notes the fact, and if the inconsistency is not subsequently cleared by supplying another value at a higher precedence, the error is reported when the checkConsistency() method is subsequently called.
