Method Detail

getMaxBlockNumber

protected int getMaxBlockNumber()

Description copied from class: SimpleBlockChooser

Can be overridden to restrict chooseKey() to a subset of the available blocks. Useful for inserts where we will be able to insert all the blocks until after encoding has finished.

Overrides:

getMaxBlockNumber in class SimpleBlockChooser

Returns:

The upper bound on the block number chosen.

onCompletedAll

protected void onCompletedAll()

Overrides:

onCompletedAll in class SimpleBlockChooser

checkValid

protected boolean checkValid(int chosen)

Description copied from class: SimpleBlockChooser

Is the proposed block valid? Override to implement custom logic e.g. checking which requests are already running.

Overrides:

checkValid in class SimpleBlockChooser

onRNF

public void onRNF(int blockNo)

Handle an RNF if the n-consecutive-RNFs-count-as-success hack is enabled. Must only be called if consecutiveRNFsCountAsSuccess > 0

pushRNFs

public boolean pushRNFs(int blockNo)

Count the previous RNFs towards the retry limit, when the following error wasn't an RNF.

write

public void write(java.io.DataOutputStream dos)
           throws java.io.IOException

Description copied from class: SimpleBlockChooser

Write everything

Overrides:

write in class SimpleBlockChooser

Throws:

java.io.IOException

read

public void read(java.io.DataInputStream dis)
          throws java.io.IOException,
                 StorageFormatException

Overrides:

read in class SimpleBlockChooser

Throws:

java.io.IOException

StorageFormatException
