C++ and C Correlator plug-in API enhancements
Correlator plug-ins written in C++ and C can now return sequences. The APIs for developing correlator plug-ins in C++ and C have been enhanced as follows:
The C++ API class
AP_Type now defines the following functions:
To set the length of an existing sequence:
void setSequenceLength(size_t length)
To create a sequence that contains empty items of the type you specify:
void createSequence(AP_TypeDescriptor inner)
Also, AP_Type objects can now be directly assigned from one to another. For example, to return the first argument, regardless of type:
rval = args[0];
The C API class
AP_PluginType_Functions now defines the following comparable functions:
void (AP_PLUGIN_CALL *setSequenceLength)(const AP_PluginType *obj, AP_uint32 len) void (AP_PLUGIN_CALL *createSequence)(const AP_PluginType *obj, AP_TypeDescriptor inner) void (AP_PLUGIN_CALL *copyFrom)(const AP_PluginType *obj, const AP_PluginType *other); For both C++ and C APIs, a sequence you create can contain items of type
integer,
float,
boolean,
string, or
chunk.
