RubyRange
public RubyRange(Ruby ruby)
init
public void init(IRubyObject begin,
IRubyObject end,
RubyBoolean isExclusive)
createRangeClass
public static RubyClass createRangeClass(Ruby ruby)
getBeginLength
public long[] getBeginLength(long limit,
boolean truncate,
boolean isStrict)
- Converts this Range to a pair of integers representing a start position
and length. If either of the range's endpoints is negative, it is added to
the
limit
parameter in an attempt to arrive at a position
p such that 0 <= p <= limit. If
truncate
is true, the result will be adjusted, if possible, so
that begin + length <= limit. If strict
is true, an exception will be raised if the range can't be converted as
described above; otherwise it just returns null.
- Parameters:
limit
- the size of the object (e.g., a String or Array) that
this range is being evaluated against.truncate
- if true, result must fit within the range (0..limit).isStrict
- if true, raises an exception if the range can't be converted.
- Returns:
- a two-element array representing a start value and a length,
or null if the conversion failed.
