public int getDefaultVersion()

Returns the version that shall be used when creating new databases.

isSupportedVersion

public boolean isSupportedVersion(int vers)

getMinSupportedVersion

public int getMinSupportedVersion()

getMaxSupportedVersion

public int getMaxSupportedVersion()

versionString

public static java.lang.String versionString(int version)

getPath

public java.io.File getPath()

getWriteNumber

scheduleDeletion

public void scheduleDeletion(long addressOfNodeToDelete)

logDoubleDeletion

protected void logDoubleDeletion(long addressOfNodeToDelete)

setData

public <T> void setData(java.lang.Class<T> key,
                        T value)

Inserts a cookie that can be later retrieved via getData(String).
