Detailed Description

template<typename T>
class pongasoft::VST::IParamSerializer< T >

A vst parameter is represented by a ParamValue type which is a double in the range [0,1].

This interface represents a way to extend the concept of parameter by allowing any type that cannot be converted to ParamValue (for example a string). The parameter simply needs to provide an implementation of this interface which represents a way to serialize/deserialize the type to the stream.

Note

This interface can also be used to simply display the parameter (even if not serializable)

Template Parameters

T	the actual type that the parameter represents

Member Function Documentation

readFromStream()

template<typename T>

virtual tresult readFromStream ( IBStreamer & iStreamer, ParamType & oValue ) const

inlinevirtual

This method should read from the stream and populate oValue accordingly (aka deserialization).

Returns

kResultOk if reading was successful, kResultFalse otherwise (or kNotImplemented if not supported)

Reimplemented in BooleanParamSerializer, DiscreteTypeParamSerializer< T, Compare >, DoubleParamSerializer, UTF8StringParamSerializer< size >, Int32ParamSerializer, Int64ParamSerializer, JmbParamDef< T >, and RawParamSerializer.

toString()

template<typename T>

virtual std::string toString ( ParamType const & iValue, int32 iPrecision ) const

inlinevirtual

writeToStream() [1/2]

template<typename T>

virtual tresult writeToStream ( const ParamType & iValue, IBStreamer & oStreamer ) const

inlinevirtual

This method should write iValue to the stream (aka serialization).

Returns

kResultOk if writing was successful, kResultFalse otherwise (or kNotImplemented if not supported)

Reimplemented in BooleanParamSerializer, DiscreteTypeParamSerializer< T, Compare >, DoubleParamSerializer, UTF8StringParamSerializer< size >, Int32ParamSerializer, Int64ParamSerializer, JmbParamDef< T >, and RawParamSerializer.

writeToStream() [2/2]

template<typename T>

virtual void writeToStream ( ParamType const & iValue, std::ostream & oStream ) const

inlinevirtual

By default, this implementation simply writes the value to the stream IF it is possible (determined at compilation time).

Doesn't do anything if not. Subclasses can redefine this behavior.

Reimplemented in DiscreteTypeParamSerializer< T, Compare >, and JmbParamDef< T >.
