Public Member Functions | |
GLogify () | |
General purpose constructor. More... | |
GLogify (const GDomNode *pNode) | |
Load from a DOM. More... | |
virtual | ~GLogify () |
virtual GDomNode * | serialize (GDom *pDoc) const |
Marshal this object into a DOM, which can then be converted to a variety of serial formats. More... | |
virtual void | transform (const GVec &in, GVec &out) |
See the comment for GIncrementalTransform::transform. More... | |
virtual void | untransform (const GVec &in, GVec &out) |
See the comment for GIncrementalTransform::untransform. More... | |

Public Member Functions inherited from GClasses::GIncrementalTransform | |
GIncrementalTransform () | |
GIncrementalTransform (const GDomNode *pNode) | |
virtual | ~GIncrementalTransform () |
const GRelation & | after () const |
Returns a relation object describing the data after it is transformed. More... | |
const GRelation & | before () const |
Returns a relation object describing the data before it is transformed. More... | |
GVec & | innerBuf () |
Returns a buffer of sufficient size to store an inner (transformed) vector. The caller should not to delete the buffer. The same buffer will be returned each time. More... | |
virtual GMatrix * | reduce (const GMatrix &in) |
This calls train, then calls transformBatch, and returns the result. More... | |
void | setAfter (GRelation *pRel) |
Sets the after relation. Takes ownership of pRel. More... | |
void | setBefore (GRelation *pRel) |
Sets the before relation. Takes ownership of pRel. More... | |
void | train (const GMatrix &data) |
Trains the transform on the data in pData. (This method may be a no-op for transformations that always behave in the same manner.) More... | |
void | train (const GRelation &pRelation) |
"Trains" the transform without any data. More... | |
virtual GMatrix * | transformBatch (const GMatrix &in) |
This assumes that train has already been called, and transforms all the rows in in returning the resulting matrix. The caller is responsible for deleting the new matrix. More... | |
virtual std::unique_ptr< GMatrix > | untransformBatch (const GMatrix &in) |
This assumes train was previously called, and untransforms all the rows in pIn and returns the results. More... | |
