Constructor Detail

Pattern.Range

public Pattern.Range()

Method Detail

optionalTrailingZeros

public static java.lang.String optionalTrailingZeros(java.lang.String rangeRegEx)

Makes trailing zeros optional.

rangeRegEx uses the following grammar:

branch = parts ('|' parts)*

parts = part+

part = number | '[' (range | number)+ ']'

range = number '-' number

number = [0-9a-zA-Z]

Parameters:

rangeRegEx - the range regular expression

Returns:

the given range regular expression, with trailing zeros optional

boundedRange

public static java.lang.String boundedRange(java.lang.String start,
                                            boolean inclusiveStart,
                                            java.lang.String end,
                                            boolean inclusiveEnd)

unboundedRange

public static java.lang.String unboundedRange(Pattern.Comparison comparison,
                                              java.lang.String value)

iPartRange

public static java.lang.String iPartRange(Pattern.Comparison comparison,
                                          java.lang.String iPart)

fPartRange

public static java.lang.String fPartRange(Pattern.Comparison comparison,
                                          java.lang.String iPart,
                                          java.lang.String fPart)

Parameters:

iPart - the integer part

fPart - the fractional part

compare

public static int compare(java.lang.String value1,
                          java.lang.String value2)

Compares two integers numerically

Parameters:

value1 -

value2 -

Returns:
