Example 7 with BufferedFileHandle

use of org.apache.hyracks.storage.common.file.BufferedFileHandle in project asterixdb by apache.

the class BufferCache method purgeHandle.

@Override
public /**
     * _ONLY_ call this if you absolutely, positively know this file has no dirty pages in the cache!
     * Bypasses the normal lifecycle of a file handle and evicts all references to it immediately.
     */
void purgeHandle(int fileId) throws HyracksDataException {
    synchronized (fileInfoMap) {
        BufferedFileHandle fh = fileInfoMap.get(fileId);
        if (fh != null) {
            ioManager.close(fh.getFileHandle());
            fileInfoMap.remove(fileId);
            fileMapManager.unregisterFile(fileId);
        }
