4. val JitActivationVersion: Byte

   

   The first version of ErgoTree starting from which the JIT costing interpreter must be used.

   The first version of ErgoTree starting from which the JIT costing interpreter must be used. It must also be used for all subsequent versions (3, 4, etc).

5. val MaxSupportedScriptVersion: Byte

   

   Maximum version of ErgoTree supported by this interpreter release.

   Maximum version of ErgoTree supported by this interpreter release. See version bits in ErgoTree.header for more details. This value should be increased with each new protocol update via soft-fork. The following values are used for current and upcoming forks: - version 3.x this value must be 0 - in v4.0 must be 1 - in v5.x must be 2 etc.

9. def current: VersionContext

   

   Returns the current VersionContext attached to the current thread.

   Returns the current VersionContext attached to the current thread. Each thread can have only one current version context at any time, which can be changed using withVersions method.

24. def withVersions[T](activatedVersion: Byte, ergoTreeVersion: Byte)(block: ⇒ T): T

    

    Executes the given block under the given version context attached to the current thread.

    Executes the given block under the given version context attached to the current thread.

    The typical usage is to use VersionContext.withVersions(activatedVersion, treeVersion) {...} when the block of code needs to be executed with the given versions.

    For example, sigmastate.Interpreter uses it to execute operations according to the necessary versions of Ergo protocol and ErgoTree.

    activatedVersion

    Currently activated script version == Block.headerVersion - 1

    ergoTreeVersion

    ErgoTree version to be set on the current thread

    block

    block of code to execute

    returns

    result of block execution
