getReadExternalReadAHead

public int getReadExternalReadAHead()

setReadExternalReadAHead

public void setReadExternalReadAHead(int readExternalReadAHead)

since the stock readXX methods on InputStream are final, i can't ensure sufficient readAhead on the inputStream before calling readExternal. Default value is 16000 bytes. If you make use of the externalizable interfac and write larger Objects a) cast the ObjectInput in readExternal to FSTObjectInput and call ensureReadAhead on this in your readExternal method b) set a sufficient maximum using this method before serializing.

Parameters:

readExternalReadAHead -
