public void writeExternal(ObjectOutput out)
                   throws IOException

Redirects the default java serialization via externalizable to our default hadoop writable serialization for efficient broadcast/rdd serialization.

Specified by:

writeExternal in interface Externalizable

Parameters:

out - object output

Throws:

IOException - if IOException occurs

                         ClassNotFoundException

Redirects the default java serialization via externalizable to our default hadoop writable serialization for efficient broadcast/rdd deserialization.

Specified by:

readExternal in interface Externalizable

Parameters:

in - object input

Throws:

IOException - if IOException occurs

ClassNotFoundException

getCleanupStates

public List<Boolean> getCleanupStates()

Gets list of current cleanupFlag values recursively for every element in the list and in its sublists of type CacheableData. The order is as CacheableData elements are discovered during DFS. Elements that are not of type CacheableData are skipped.

Returns:

list of booleans containing the _cleanupFlag values.

enableCleanup

public void enableCleanup(boolean flag)

Sets the cleanupFlag values recursively for every element of type CacheableData in the list and in its sublists to the provided flag value.

Parameters:

flag - New value for every CacheableData element.

enableCleanup

public void enableCleanup(Queue<Boolean> flags)

Sets the cleanupFlag values recursively for every element of type CacheableData in the list and in its sublists to the provided values in flags. The cleanupFlag value of the i-th CacheableData element in the list (counted in the order of DFS) is set to the i-th value in flags.

Parameters:

flags - Queue of values in the same order as its corresponding elements occur in DFS.
