    Class
    Description
    BooleanExpressionTransformer
    Transforms a && b into if(a, b, false) and a || b into if(a, true, b) to avoid computing b if a is false and true respectively.
    ConstantTensorTransformer
    Transforms named references to constant tensors with the rank feature 'constant'.
    ExpressionTransforms
    The transformations done on ranking expressions done at config time before passing them on to the Vespa engine for execution.
    FunctionInliner
    Inlines functions in ranking expressions
    FunctionShadower
    Transforms function nodes to reference nodes if a rank profile function shadows a built-in function.
    LightGBMFeatureConverter
    Replaces instances of the lightgbm(model-path) pseudofeature with the native Vespa ranking expression implementing the same computation.
    OnnxFeatureConverter
    Replaces instances of the onnx(model-path, output) pseudofeature with the native Vespa ranking expression implementing the same computation.
    OnnxModelTransformer
    Transforms ONNX model features of the forms: onnx(config_name) onnx(config_name).output onnx("path/to/model") onnx("path/to/model").output onnx("path/to/model", "path/to/output") onnx("path/to/model", "unused", "path/to/output") // signature is unused To the format expected by the backend: onnx(config_name).output
    RankProfileTransformContext
    Extends the transform context with rank profile information
    TensorFlowFeatureConverter
    Replaces instances of the tensorflow(model-path, signature, output) pseudofeature with the native Vespa ranking expression implementing the same computation.
    TokenTransformer
    Convenience feature transforms for inputs to Transformer type models.
    XgboostFeatureConverter
    Replaces instances of the xgboost(model-path) pseudofeature with the native Vespa ranking expression implementing the same computation.
