FloatParameter

A float parameter This is an abstract class, mapping from normalized to parmeter values is left to the user.

class FloatParameter : Parameter {

double value();

double valueAtomic();

void setDecimalPrecision(int digits);

double toNormalized(double value);

double fromNormalized(double value);

}

Functions

fromNormalized double fromNormalized(double value): Override it to specify mapping from normalized [0..1] to parameter value
setDecimalPrecision void setDecimalPrecision(int digits): Sets the number of decimal digits after the dot to be displayed.
toNormalized double toNormalized(double value): Override it to specify mapping from parameter values to normalized [0..1]
value double value(): Gets current value.
valueAtomic double valueAtomic(): Same as value but doesn't use locking, and doesn't use ordering. Which make it a better fit for the audio thread.

name string name()
label string label()
index int index()
setFromHost void setFromHost(double hostValue): From a normalized double [0..1], set the parameter value.
getForHost double getForHost()
addListener void addListener(IParameterListener listener): Adds a parameter listener.
removeListener void removeListener(IParameterListener listener): Removes a parameter listener.
beginParamEdit void beginParamEdit(): Warns the host that a parameter will be edited. Should only ever be called from the UI thread.
endParamEdit void endParamEdit(): Warns the host that a parameter has finished being edited. Should only ever be called from the UI thread.
getNormalized double getNormalized()
getNormalizedDefault double getNormalizedDefault()
stringFromNormalizedValue void stringFromNormalizedValue(double normalizedValue, char* buffer, size_t len)
normalizedValueFromString bool normalizedValueFromString(const(char)[] valueString, double result)
isDiscrete bool isDiscrete()
setNormalized void setNormalized(double hostValue): From a normalized double, set the parameter value. No guarantee at all that getNormalized will return the same, because this value is rounded to fit.
toStringN void toStringN(char* buffer, size_t numBytes): Display parameter (without label). This always adds a terminal zero within numBytes.
setClientReference void setClientReference(Client client): Parameters are owned by a client, this is used to make them refer back to it.
