Functions
DLLEXPORT QoreValue	qore_type_assign_value (const QoreTypeInfo *t, const QoreValue value, ExceptionSink *xsink)
	processes the given value by the given type and returns the result; a Qore-language exception is thrown if the value is not assignable to the type More...
DLLEXPORT bool	qore_type_can_convert_to_scalar (const QoreTypeInfo *ti)
	returns true if the type's value can be converted to a scalar; the argument may be nullptr meaning no type restrictions
DLLEXPORT bool	qore_type_equal (const QoreTypeInfo *ti1, const QoreTypeInfo *ti2)
	returns true if the types are equal; either argument may be nullptr meaning no type restrictions

	returns a hash of base types accepted by the type More...

	returns the base type code for the type or NT_ALL for those that don't have types More...
DLLEXPORT QoreValue	qore_type_get_default_value (const QoreTypeInfo *ti)
	returns the default value of the type (if any); the caller owns any reference returned; the argument may be nullptr meaning no type restrictions

qore_type_assign_value()

DLLEXPORT QoreValue qore_type_assign_value	(	const QoreTypeInfo *	t,
		const QoreValue	value,
		ExceptionSink *	xsink
	)

processes the given value by the given type and returns the result; a Qore-language exception is thrown if the value is not assignable to the type

Since

Qore 0.9.4

qore_type_get_accept_types()

DLLEXPORT QoreHashNode* qore_type_get_accept_types

(

const QoreTypeInfo *

t

)

returns a hash of base types accepted by the type

Since

Qore 0.9.4

qore_type_get_base_type()

DLLEXPORT qore_type_t qore_type_get_base_type

(

const QoreTypeInfo *

t

)

returns the base type code for the type or NT_ALL for those that don't have types

Since

Qore 0.9.4

qore_type_get_return_types()

DLLEXPORT QoreHashNode* qore_type_get_return_types

(

const QoreTypeInfo *

t

)

returns a hash of base types returned by the type

Since

Qore 0.9.4

qore_type_is_assignable_from() [1/3]

DLLEXPORT bool qore_type_is_assignable_from	(	const QoreTypeInfo *	ti1,
		const QoreTypeInfo *	ti2
	)

returns true if ti2's return type is compatible with ti1 input (i.e. ti1 is assignable from ti2)

Parameters

ti1	the type to check assignability to
ti2	the type to see if it can be assigned to ti1

Returns

true if ti2's return type is compatible with ti1 input (i.e. ti1 is assignable from ti2)

either argument may be nullptr meaning no type restrictions

Since

Qore 0.9.4

qore_type_is_assignable_from() [2/3]

DLLEXPORT bool qore_type_is_assignable_from	(	const QoreTypeInfo *	ti1,
		const QoreTypeInfo *	ti2,
		bool &	may_not_match
	)

returns true if ti2's return type is compatible with ti1 input (i.e. ti1 is assignable from ti2)

Parameters

ti1	the type to check assignability to
ti2	the type to see if it can be assigned to ti1
may_not_match	an output variable, if true then the assignment is not guaranteed to succeed and may fail at runtime

Returns

true if ti2's return type is compatible with ti1 input (i.e. ti1 is assignable from ti2)

either argument may be nullptr meaning no type restrictions

Since

Qore 0.9.4

qore_type_is_assignable_from() [3/3]

DLLEXPORT int qore_type_is_assignable_from	(	const QoreTypeInfo *	t,
		QoreValue	value
	)

returns true if the given type can be assigned from the given value

Parameters

t	the type to check assignability to
value	the value to check if it can be assigned to t

Returns

a type match code for the assignability

The type argument t may be nullptr meaning no type restrictions

Since

Qore 0.9.4
