Class SmartSpool

java.lang.Object
  com.atlassian.core.spool.SmartSpool

All Implemented Interfaces:

Spool, ThresholdingSpool

public class SmartSpool

extends java.lang.Object

implements ThresholdingSpool

Spool that delegates to the overThresholdSpool immediately if InputStream::available() is greater than the threshold of the secondary Thresholding spool. This avoids needless spooling of data into memory from InputStreams with large amounts of initial data available

Constructor Summary

SmartSpool()

Method Summary

int	getThresholdBytes()
void	setOverThresholdSpool(Spool overThresholdSpool) Set the spooling strategy to use when InputStream::available is greater than the threshold of the configured ThresholdingSpool
void	setThresholdBytes(int bytes)
void	setThresholdingSpool(ThresholdingSpool thresholdingSpool) Set the spooling strategy that will be used when InputStream::available() is less than or equal to the value of the strategy's threshold.
java.io.InputStream	spool(java.io.InputStream is) Return a new InputStream to the data provided.

Method Detail

setThresholdBytes

public void setThresholdBytes(int bytes)

Specified by:

setThresholdBytes in interface ThresholdingSpool

getThresholdBytes

public int getThresholdBytes()

Specified by:

getThresholdBytes in interface ThresholdingSpool

spool

public java.io.InputStream spool(java.io.InputStream is)
                          throws java.io.IOException

Description copied from interface: Spool

Return a new InputStream to the data provided. Implementations should guarantee that the returned input stream is independent of the stream passed in. For example, the returned InputStream should still be useable once the original InputStream is closed and its associated resources are released.

Specified by:

spool in interface Spool

Parameters:

is - - Source stream to be spooled

Returns:

Spooled stream

Throws:

java.io.IOException

setOverThresholdSpool

public void setOverThresholdSpool(Spool overThresholdSpool)

Set the spooling strategy to use when InputStream::available is greater than the threshold of the configured ThresholdingSpool

Parameters:

overThresholdSpool -

setThresholdingSpool

public void setThresholdingSpool(ThresholdingSpool thresholdingSpool)

Set the spooling strategy that will be used when InputStream::available() is less than or equal to the value of the strategy's threshold.

Parameters:

thresholdingSpool -
