org.apache.lucene.benchmark.byTask.utils.StringBuilderReader
- All Implemented Interfaces:
- Closeable, Readable
public class StringBuilderReader
- extends Reader
Implements a Reader
over a StringBuilder
instance. Although
one can use StringReader
by passing it
StringBuilder.toString()
, it is better to use this class, as it
doesn't mark the passed-in StringBuilder
as shared (which will cause
inner char[] allocations at the next append() attempt).

StringBuilderReader
public StringBuilderReader(StringBuilder sb)
close
public void close()
- Specified by:
close
in interface Closeable
- Specified by:
close
in class Reader
mark
public void mark(int readAheadLimit)
throws IOException
- Mark the present position in the stream. Subsequent calls to reset() will
reposition the stream to this point.
- Overrides:
mark
in class Reader
- Parameters:
readAheadLimit
- Limit on the number of characters that may be read
while still preserving the mark. Because the stream's input comes
from a StringBuilder, there is no actual limit, so this argument
must not be negative, but is otherwise ignored.
- Throws:
IllegalArgumentException
- If readAheadLimit is < 0
IOException
- If an I/O error occurs
