Constructor Detail

NumberPattern

public NumberPattern(String regex,
                     int radix,
                     int cutFromStart,
                     int cutFromEnd)

Create instance of the NumberPattern

Parameters:

regex - Regular expression for the number parser

radix - The radix that the pattern represents

cutFromStart - Count of characters that will be cut from the beginning of a number by calling prepareNumber method.

cutFromEnd - Count of characters that will be cut from the end of a number by calling prepareNumber method.

Method Detail

matches

public boolean matches(String number)

Determines if a number represented as String matches this NumberPattern.

Parameters:

number - the number String representation

Returns:

true if the number matches this pattern, false otherwise

getRadix

public int getRadix()

Get radix of this NumberPattern

Returns:

radix of this pattern

prepareNumber

public String prepareNumber(String number)

Prepares the number for radix conversion. It formats given number into a form that does not contain any additional characters for radix recognition. For example, pattern

0x[0-9a-fA-F]+

, representing hexadecimal number, contains some characters needed for pattern recognition, they are the first two (

0x

). The numbers of left and right cut are defined in the constructor.

Parameters:

number - the number String representation

Returns:

String number prepared for radix conversion.
