Method Detail

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Specified by:

close in class Directory

Throws:

IOException

isOpen

public boolean isOpen()

indexPossiblyExists

protected boolean indexPossiblyExists()

don't rely upon DirectoryReader.fileExists to determine if we should checkIndex() or not. It might mask real problems, where we silently don't checkindex at all. instead we look for a segments file.

setCheckIndexOnClose

public void setCheckIndexOnClose(boolean value)

Set whether or not checkindex should be run on close

getCheckIndexOnClose

public boolean getCheckIndexOnClose()

setCrossCheckTermVectorsOnClose

public void setCrossCheckTermVectorsOnClose(boolean value)

getCrossCheckTermVectorsOnClose

public boolean getCrossCheckTermVectorsOnClose()

listAll

public String[] listAll()
                 throws IOException

Specified by:

listAll in class Directory

Throws:

IOException
