Modifier and Type	Method and Description
boolean	areEqualitiesBetweenTwoDBAttributesStrict() Returns true if the non-strict equality between two attributes of the same database of this type is equivalent to a strict equality.
boolean	areEqualitiesStrict() NB: here we ignore the presence of + and 0s on the left (for the sake of simplicity) TODO: stop ignoring this presence

Optional<RDFDatatype>	getNaturalRDFDatatype()
boolean	isNeedingIRISafeEncoding() False by default as the vast majority of number formats are not sensible to IRI safe encoding.

Method Detail

getNaturalRDFDatatype

public Optional<RDFDatatype> getNaturalRDFDatatype()

isNeedingIRISafeEncoding

public boolean isNeedingIRISafeEncoding()

False by default as the vast majority of number formats are not sensible to IRI safe encoding. In theory rationals would pose problems if they use the "/" character, but I have so far never seen them in a DB.

areEqualitiesStrict

public boolean areEqualitiesStrict()

NB: here we ignore the presence of + and 0s on the left (for the sake of simplicity) TODO: stop ignoring this presence

areEqualitiesStrict

public Optional<Boolean> areEqualitiesStrict(DBTermType otherType)

Description copied from interface: DBTermType

Returns true if the non-strict equality between terms of these two types are equivalent to a strict equality

areEqualitiesBetweenTwoDBAttributesStrict

public boolean areEqualitiesBetweenTwoDBAttributesStrict()

Description copied from interface: DBTermType

Returns true if the non-strict equality between two attributes of the same database of this type is equivalent to a strict equality. Useful for floating numbers. Note that we are NOT considering here equalities with constants coming from source part of the mapping assertion.

getCastName

public String getCastName()

Description copied from class: DBTermTypeImpl

Default implementation, can be overridden

Specified by:

getCastName in interface DBTermType

Overrides:

getCastName in class DBTermTypeImpl
