Method Summary

Modifier and Type	Method and Description
ReIterator<MemoryKey>	keys(KeyMode keyMode)
ReIterator<FactHandleVersioned>	values(KeyMode mode, MemoryKey key)
void	write(Collection<FactHandleVersioned> factHandles) This method will be called after necessary count of keys are provided via write(ValueHandle).
void	write(ValueHandle partialKey) Method similar to the JarOutputStream.putNextEntry(ZipEntry), except both sides are expected to know how many keys are to be written until write(Collection) gets called.

Method Detail

keys

ReIterator<MemoryKey> keys(KeyMode keyMode)

values

ReIterator<FactHandleVersioned> values(KeyMode mode,
                                       MemoryKey key)

write

void write(ValueHandle partialKey)

Method similar to the JarOutputStream.putNextEntry(ZipEntry), except both sides are expected to know how many keys are to be written until write(Collection) gets called.

Parameters:

partialKey - next component of the memory key

write

void write(Collection<FactHandleVersioned> factHandles)

This method will be called after necessary count of keys are provided via write(ValueHandle). After fact handles are provided, the implementation must reset its internal key counter and wait for the next call of write(ValueHandle).

Parameters:

factHandles - fact handles to save under the sequence of keys
