Defines an evaluation semantics of this tree node (aka Value or expression) in the given data environment.
Defines an evaluation semantics of this tree node (aka Value or expression) in the given data environment.
Should be implemented by all the ErgoTree nodes (aka operations).
Thus, the ErgoTree interpreter implementation consists of combined implementations of this method.
NOTE, this method shouldn't be called directly, instead use evalTo method.
immutable map, which binds variables (given by ids) to the values
Evaluator which defines evaluation context, cost accumulator, settings etc.
the data value which is the result of evaluation
Evaluates this node to the value of the given expected type.
Evaluates this node to the value of the given expected type.
This method should called from all eval implementations.
expected type of the resulting value

Name of the operation.
Name of the operation.
Every value represents an operation and that operation can be associated with a function type, describing functional meaning of the operation, kind of operation signature.
Every value represents an operation and that operation can be associated with a function type, describing functional meaning of the operation, kind of operation signature. Thus, we can obtain global operation identifiers by combining Value.opName with Value.opType, so that if (v1.opName == v2.opName) && (v1.opType == v2.opType) then v1 and v2 are functionally point-wise equivalent. This in particular means that if two _different_ ops have the same opType they _should_ have different opNames. Thus defined op ids are used in a v4.x Cost Model - a table of all existing primitives coupled with performance parameters.

The type of the value represented by this node.
The type of the value represented by this node. If the value is an operation it is the type of operation result.
Transforms serialized bytes of ErgoTree with segregated constants by replacing constants at given positions with new values. This operation allow to use serialized scripts as pre-defined templates. The typical usage is "check that output box have proposition equal to given script bytes, where minerPk (constants(0)) is replaced with currentMinerPk". Each constant in original scriptBytes have SType serialized before actual data (see ConstantSerializer). During substitution each value from newValues is checked to be an instance of the corresponding type. This means, the constants during substitution cannot change their types.
