Class to generate dense features data via the streaming features interface. The core are pairs of methods to a) set the data model and parameters, and b) to generate a data vector using these model parameters Both methods are automatically called when calling get_next_example() This allows to treat generated data as a stream via the standard streaming features interface.
Streaming based data generator that samples from a distribution that is a 2D grid-like mixture of a number Gaussians at a certain distance from each other, and where each Gaussian is stretched and rotated by a factor.

Takes a set of TParameter instances (base) with a certain version and a set of target parameter infos and recursively maps the base level wise to the current version using CSGObject::migrate(...). The base is replaced. After this call, the base version containing parameters should be of same version/type as the initial target parameter infos. Note for this to work, the migrate methods and all the internal parameter mappings have to match

creates a new TParameter instance, which contains migrated data from the version that is provided. The provided parameter data base is used for migration, this base is a collection of all parameter data of the previous version. Migration is done FROM the data in param_base TO the provided param info Migration is always one version step. Method has to be implemented in subclasses, if no match is found, base method has to be called.
If there is an element in the param_base which equals the target, a copy of the element is returned. This represents the case when nothing has changed and therefore, the migrate method is not overloaded in a subclass

This method prepares everything for a one-to-one parameter migration. One to one here means that only ONE element of the parameter base is needed for the migration (the one with the same name as the target). Data is allocated for the target (in the type as provided in the target SGParamInfo), and a corresponding new TParameter instance is written to replacement. The to_migrate pointer points to the single needed TParameter instance needed for migration. If a name change happened, the old name may be specified by old_name. In addition, the m_delete_data flag of to_migrate is set to true. So if you want to migrate data, the only thing to do after this call is converting the data in the m_parameter fields. If unsure how to use - have a look into an example for this. (base_migration_type_conversion.cpp for example)

Set the vector reading functions.
The functions are implemented specific to the type in the derived class.

Sets the read function (in case the examples are labelled) to get_*_vector_and_label from CStreamingFile.
The exact function depends on type T.
The parser uses the function set by this while reading labelled examples.
实现了 CStreamingFeatures.

Sets the read function (in case the examples are unlabelled) to get_*_vector() from CStreamingFile.
The exact function depends on type T.
The parser uses the function set by this while reading unlabelled examples.
