Interface DBTypeConversionFunctionSymbol

All Superinterfaces:

DBFunctionSymbol, DBFunctionSymbolSerializer, FunctionSymbol, Predicate, Serializable

All Known Implementing Classes:

AbstractDBTypeConversionFunctionSymbolImpl, AbstractTimestampISODenormFunctionSymbol, AbstractTimestampISONormFunctionSymbol, DefaultBooleanDenormFunctionSymbol, DefaultBooleanNormFunctionSymbol, DefaultCastIntegerToStringFunctionSymbol, DefaultNumberNormAsBooleanFunctionSymbol, DefaultSimpleDBBooleanCastFunctionSymbol, DefaultSimpleDBCastFunctionSymbol, DefaultTimeTzNormalizationFunctionSymbol, MockupSimpleDBBooleanCastFunctionSymbol, MockupSimpleDBCastFunctionSymbol, NonPostProcessedSimpleDBCastFunctionSymbol, OneDigitBooleanNormFunctionSymbolImpl, OneLetterBooleanNormFunctionSymbolImpl, TemporaryDBTypeConversionToStringFunctionSymbolImpl

public interface DBTypeConversionFunctionSymbol
extends DBFunctionSymbol

Slightly more general abstraction than a regular DB cast, as it MAY perform some normalization to a specific format.

Method Detail

getTargetType

DBTermType getTargetType()

getInputType

Optional<DBTermType> getInputType()

isTemporary

boolean isTemporary()

isSimple

boolean isSimple()

Returns true if does not transform the string representation of the value (i.e. no normalization). Useful for simplifying nested casts ( A-to-B(B-to-A(x)) === x if both casts are simple)

isTemporary

static boolean isTemporary(FunctionSymbol fs)

uncast

static ImmutableTerm uncast(ImmutableTerm term)
