类 DataFactory

java.lang.Object

com.vladium.emma.data.DataFactory

public abstract class DataFactory
extends java.lang.Object

Persistence and Factory API for metadata and coverage data. This implementation works with custom read/writeExternal() methods (note that those are not Externalizable implementations), which results in significant (3x-5x) serialization speed-up for large amounts of data.

NOTE: file locking for concurrent writing is handled at the caller level.
