Constructor Detail

FSTObjectInput

public FSTObjectInput()
               throws IOException

Throws:

IOException

FSTObjectInput

public FSTObjectInput(FSTConfiguration conf)
               throws IOException

Throws:

IOException

FSTObjectInput

public FSTObjectInput(InputStream in)
               throws IOException

Creates a FSTObjectInput that uses the specified underlying InputStream.

Parameters:

in - the specified input stream

Throws:

IOException

FSTObjectInput

public FSTObjectInput(InputStream in,
              FSTConfiguration conf)
               throws IOException

Creates a FSTObjectInput that uses the specified underlying InputStream. Don't create a FSTConfiguration with each stream, just create one global static configuration and reuseit. FSTConfiguration is threadsafe.

Parameters:

in - the specified input stream

Throws:

IOException

Method Detail

getConf

public FSTConfiguration getConf()

getConditionalCallback

public FSTObjectInput.ConditionalCallback getConditionalCallback()

setConditionalCallback

public void setConditionalCallback(FSTObjectInput.ConditionalCallback conditionalCallback)

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 -

readFPrimitiveArray
