Public Member Functions

virtual bool canBeHazardous () const
 Can this filter perform actions that are potentially a security concern?
virtual void clearCache ()
 Erase cache.
FiltercloneUncached () const
 Duplicate filter contents, excluding cache.
std::string getErrString (unsigned int code) const
 Get the human readable error string associated with a particular error code during refresh(...).
unsigned int getNumOutput (unsigned int streamType) const
 Get the number of outputs for the specified type during the filter's last refresh.
void getOutputData (std::vector< FilterStreamData * > *&getOut)
 Get the filter output data from this filter.
void getProperties (FilterProperties &propertyList) const
 Get the properties of the filter, in key-value form. First vector is for each output.
void getSelectionDevices (vector< SelectionDevice * > &devices)
 Get the selection devices for this filter. MUST be called after refresh().
unsigned int getType () const
 Returns FILTER_TYPE_IONDOWNSAMPLE.
virtual std::string getUserString () const
 Return a user-specified string, or just the typestring if user set string not active.
bool haveCache () const
 Have cached output data?
bool isEnabled () const
virtual size_t numBytesForCache (size_t nObjects) const
 Get (approx) number of bytes required for cache.
bool readState (xmlNodePtr &node)
 Read the state of the filter from XML file. If this.
unsigned int refresh (const std::vector< const FilterStreamData * > &dataIn, std::vector< const FilterStreamData * > &getOut, unsigned int &progress, bool(*callback)(void))
 Apply filter to new data, updating cache as needed. Vector of returned pointers must be deleted manually, first checking ->cached.
void setCaching (bool enableCache)
 Enable/disable caching for this filter.
void setControlledOut (bool controlled)
 Set mode, fixed num out/approximate out (fraction).
void setFilterCount (size_t nMax)
 Set the number of ions to generate after the filtering (when using count based fitlering).
bool setProperty (unsigned int set, unsigned int key, const std::string &value, bool &needUpdate)
 Set the properties for the nth filter.
void setPropFromBinding (const SelectionBinding &b)
 Set internal property value using a selection binding (Disabled, this filter has no bindings).
virtual void setUserString (const std::string &str)
 Set a user-specified string.
virtual std::string typeString () const
 return string naming the human readable type of this class
void updateOutputInfo (const std::vector< const FilterStreamData * > &dataOut)
 Update the output informaiton for this filter.
bool writeState (std::ofstream &f, unsigned int format, unsigned int depth=0) const
 Dump state to output stream, using specified format.

Protected Attributes

bool cache
bool cacheOK
std::vector< SelectionDevice * > devices
 User interaction "Devices" associated with this filter.
bool enabled
 Is this filter active?
std::vector< FilterStreamData * > filterOutputs
unsigned int numStreamsLastRefresh [NUM_STREAM_TYPES]
 Array of the number of streams propagated on last refresh.
unsigned int progress
std::string userString
 User settable labelling string (human readable ID, etc etc).

Private Attributes

bool fixedNumOut
 Allow only a fixed number at output, alternate is random fraction (binomial dist).
float fraction
size_t maxAfterFilter
RandNumGen rng
