Public Member Functions

Patchablein_signal ()
 Sets "signal" as selected input and returns this Unit ready to be patched. This is the default input. The signal of this input will be sampled on trigger.
 
Patchablein_trig ()
 Sets "trig" as selected input and returns this Unit ready to be patched. On a trigger on value the signal is sampled,.
 
Patchableout_signal ()
 Sets "signal" as selected output and returns this Unit ready to be patched. This is the default output. Outputs the last sampled value.
 
float meter_output () const
 returns the last sampled value. This method is thread-safe.

OutputNodegetSelectedOutput ()
 returns the selected output, you can patch it to another Patchable or InputNode with the >> operator.
 
std::vector< std::string > getInputsList ()
 returns a vector of the valid input tags
 
std::vector< std::string > getOutputsList ()
 returns a vector of the valid input tags

Detailed Description

Sample & Hold unit.

This unit continously outputs the last sampled signal. Each time a trigger on value is found in in_trig() the input in in_signal() is sampled.
