14. def eval(sigmaContext: Context, costAccumulator: CostAccumulator, constants: Seq[Constant[SType]], exp: SValue, evalSettings: EvalSettings): (Any, Int)

    

    Evaluate the given expression in the given Ergo context using the given settings.

    Evaluate the given expression in the given Ergo context using the given settings. The given Value is evaluated as-is and is not changed during evaluation.

    sigmaContext

    special.sigma.Context instance used for script execution

    costAccumulator

    CostAccumulator instance used for accumulating costs

    constants

    collection of segregated constants which can be refered by ConstantPlaceholders in exp

    exp

    ErgoTree expression represented as sigmastate.Values.Value

    evalSettings

    evaluation settings

    returns

    1) the result of evaluating exp in a given context and 2) an accumulated JIT cost estimation.

15. def eval(context: ErgoLikeContext, constants: Seq[Constant[SType]], exp: SValue, evalSettings: EvalSettings): (Any, Int)

    

    Evaluate the given expression in the given Ergo context using the given settings.

    Evaluate the given expression in the given Ergo context using the given settings. The given Value is evaluated as-is and is not changed during evaluation.

    context

    ErgoLikeContext used for script execution

    constants

    collection of segregated constants which can be refered by ConstantPlaceholders in exp

    exp

    ErgoTree expression represented as Value

    evalSettings

16. def evalToCrypto(context: ErgoLikeContext, ergoTree: ErgoTree, evalSettings: EvalSettings): ReductionResult

    

    Evaluate the given ErgoTree in the given Ergo context using the given settings.

    Evaluate the given ErgoTree in the given Ergo context using the given settings. The given ErgoTree is evaluated as-is and is not changed during evaluation.

    context

    ErgoLikeContext used for script execution

    ergoTree

    script represented as ErgoTree

    evalSettings

18. def forProfiling(profiler: Profiler, evalSettings: EvalSettings): ErgoTreeEvaluator

    

    Creates a new ErgoTreeEvaluator instance with the given profiler and settings.

    Creates a new ErgoTreeEvaluator instance with the given profiler and settings. The returned evaluator can be used to initialize the currentEvaluator variable. As a result, cost-aware operations (code blocks) can be implemented, even when those operations don't involve ErgoTree evaluation. As an example, see methods in sigmastate.SigSerializer and sigmastate.FiatShamirTree where cost-aware code blocks are used.
