isSetOrListCollection

protected boolean isSetOrListCollection(SymTypeExpression type)

whether a type is a Set or List, this differs between languages (s.a. OCL)

getContainedExpressions

protected Optional<List<ASTExpression>> getContainedExpressions(ASTSetEnumeration expr)

Get all expressions within the set enumeration. E.g.: "{1, 2..4}" -> "1","2","4" Returns empty on error (will have been logged)

getContainedExpressionTypes

protected List<SymTypeExpression> getContainedExpressionTypes(ASTSetEnumeration expr)

Get all expressions' types within the set enumeration. They need to be stored in Type4Ast before calling this. E.g.: "{1, 2..4}" -> int, int, int May contain Obscure (error will have been logged).

assertRangesContainIntegrals

protected boolean assertRangesContainIntegrals(ASTSetEnumeration expr)

s. assertRangeContainsIntegrals(ASTSetValueRange)

assertRangeContainsIntegrals

protected boolean assertRangeContainsIntegrals(ASTSetValueRange range)

Logs an error if the lower and upper bounds of the range are not integral types.

Returns:

true iff no error occurred.
