AbstractSegmentedStoreConfiguration

public AbstractSegmentedStoreConfiguration(AttributeSet attributes,
                                           AsyncStoreConfiguration async,

Method Detail

newConfigurationFrom

public abstract T newConfigurationFrom(int segment)

Method that is invoked each time a new store is created for a segment. This method should return a new configuration that is configured to be persisted using the given segment.

Parameters:

segment - the segment to use

Returns:

the newly created configuration

fileLocationTransform

protected static String fileLocationTransform(String location,
                                              int segment)

Transforms a file location to a segment based one. This is useful for file based stores where all you need to do is append a segment to the name of the directory. If the provided location is a directory, that is that it is terminated by in File.separatorChar, it will add a new directory onto that that is the segment. If the location is a file, that is that it is not terminated by File.separatorChar, this will treat the location as a directory and append a segment file in it. The underlying store may or may not preseve this and could still turn the segment into a directory.

Parameters:

location - original file location

segment - the segment to append

Returns:

string with the segment appended to the file location
