public final class SequenceScalarUnion extends BinaryDerivation
Represents the setwise union of two base variables, each of which is a collection. This variable contains every element that is in either of the base variables, but this variable contains no duplicate elements. Elements are in order of first appearance in the base variables (base1 first).- See Also:

computeValueAndModifiedImpl
public ValueAndModified computeValueAndModifiedImpl(ValueTuple full_vt)
Description copied from class:BinaryDerivation
Actual implementation once mods are handled.- Specified by:
computeValueAndModifiedImpl
in classBinaryDerivation
-
makeVarInfo
protected VarInfo makeVarInfo()
Description copied from class:Derivation
Used by all child classes to actually create the VarInfo this represents, after which it is interned for getVarInfo().- Specified by:
makeVarInfo
in classDerivation
-
isSameFormula
@Pure public boolean isSameFormula(Derivation other)
Description copied from class:Derivation
Returns true iff other and this represent the same derivation (modulo the variable they are applied to). Default implentation will just checks run-time type, but subclasses with state (e.g. SequenceInitial index) should match that, too.- Specified by:
isSameFormula
in classDerivation
- Parameters:
other
- the Derivation to compare to- Returns:
- true iff other and this represent the same derivation
-
esc_name
@SideEffectFree public String esc_name(String index)
Returns the ESC name.- Overrides:
