resetAndReuseEventInstance

public void resetAndReuseEventInstance(Object entity,
                                       EntityEntry entry)

This is a terrible anti-pattern, but particular circumstances call for being able to reuse the same event instance: this is otherwise allocated in hot loops and since each event is escaping the scope it's actually causing allocation issues. The flush event does not appear to be used recursively so this is currently safe to do, nevertheless we add an allowedToReuse flag to ensure only instances whose purpose has completed are being reused. N.B. two out of three parameters from the constructor are reset: the same EventSource is implied on reuse.

Parameters:

entity - same as constructor parameter

entry - same as constructor parameter

isAllowedToReuse

public boolean isAllowedToReuse()

setAllowedToReuse

public void setAllowedToReuse(boolean allowedToReuse)

getInstanceGenerationId

public int getInstanceGenerationId()

setInstanceGenerationId

public void setInstanceGenerationId(int instanceGenerationId)
