NumberInput
public NumberInput()
parseInt
public static final int parseInt(char[] digitChars,
int offset,
int len)
- Fast method for parsing integers that are known to fit into
regular 32-bit signed int type. This means that length is
between 1 and 9 digits (inclusive)
Note: public to let unit tests call it
parseLong
public static final long parseLong(char[] digitChars,
int offset,
int len)
inLongRange
public static final boolean inLongRange(char[] digitChars,
int offset,
int len,
boolean negative)
- Helper method for determining if given String representation of
an integral number would fit in 64-bit Java long or not.
Note that input String must NOT contain leading minus sign (even
if 'negative' is set to true).
- Parameters:
negative
- Whether original number had a minus sign (which is
NOT passed to this method) or not
inLongRange
public static final boolean inLongRange(String numberStr,
boolean negative)
- Similar to
inLongRange(char[],int,int,boolean)
, but
with String argument
- Parameters:
negative
- Whether original number had a minus sign (which is
NOT passed to this method) or not- Since:
