Method Detail

prepareUpdate

public void prepareUpdate(S stockedCount)

Description copied from interface: IResizer

Prepare an update (calculate next value of expectedSize). When this method returns the calcul must be complete (no asynchronous mechanism can be used).

Parameters:

stockedCount - statistics

update

public void update()

This method do not use asynchronous mechanism, so call to setExpectedSize will be made before this method returns.

setExpectedSparePool

public void setExpectedSparePool(int expectedSparePool)

Parameters:

expectedSparePool - the expectedSparePool to set

setMaxPool

public void setMaxPool(int maxPool)

setMinPool

public void setMinPool(int minPool)
