trait SigmaDslBuilder extends AnyRef
Runtime representation of SGlobal ErgoTree type.
The only instance of SGlobal type can be referenced as Global variable in ErgoScript.
It is represented as org.ergoplatform.Global node of ErgoTree, which evaluates to
the default singleton instance of this interface.
CostingSigmaDslBuilder object serves as the default singleton instance of Global object, which implements global ErgoTree functions.

- abstract def substConstants[T](scriptBytes: Coll[Byte], positions: Coll[Int], newValues: Coll[T]): Coll[Byte]
Transforms serialized bytes of ErgoTree with segregated constants by replacing constants at given positions with new values.
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.
- scriptBytes
serialized ErgoTree with ConstantSegregationFlag set to 1.
- positions
zero based indexes in ErgoTree.constants array which should be replaced with new values
- newValues
new values to be injected into the corresponding positions in ErgoTree.constants array
- returns
original scriptBytes array where only specified constants are replaced and all other bytes remain exactly the same
- abstract def toBigInteger(n: BigInt): BigInteger

java.math.BigIntegerfrom DSL'sBigInttype - abstract def xor(l: Coll[Byte], r: Coll[Byte]): Coll[Byte]
Returns a byte-wise XOR of the two collections of bytes.
- abstract def xorOf(conditions: Coll[Boolean]): Boolean
Similar to
allOf, but performing logical XOR operation between all conditions.
