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

StringBufferReader
public StringBufferReader(java.lang.StringBuffer sb)
close
public void close()
- Specified by:
close
in interface java.io.Closeable
- Specified by:
close
in class java.io.Reader
mark
public void mark(int readAheadLimit)
throws java.io.IOException
- Mark the present position in the stream. Subsequent calls to reset() will
reposition the stream to this point.
- Overrides:
mark
in class java.io.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 StringBuffer, there is no actual limit, so this argument
must not be negative, but is otherwise ignored.
- Throws:
java.lang.IllegalArgumentException
- If readAheadLimit is < 0
java.io.IOException
- If an I/O error occurs
markSupported
public boolean markSupported()
- Overrides:
markSupported
in class java.io.Reader
read
public int read()
throws java.io.IOException
- Overrides:
read
in class java.io.Reader

read
public int read(char[] cbuf,
int off,
int len)
throws java.io.IOException
- Specified by:
