Member Enumeration Documentation

Type

enum class knowCore::ConstrainedValue::Type

strong

Enumerator
Inferior	such as value < constraint.value
Superior	such as constraint.value < value
InferiorEqual	such as value <= constraint.value
SuperiorEqual	such as constraint.value <= value
GeoOverlaps	such as value overlaps with constraint.value (but they cannot share a boundary)
GeoWithin	such as value is within the constraint.value
GeoContains	such as constraint.value is within the value
GeoIntersects	such as value intersects with constraint.value,
GeoTouches	such as value touches with constraint.value,
GeoDisjoint	such as value disjoint with constraint.value,
Contains	such as list contains a value
NotContains	such as list does not contains a value
In	such as one value is part of a list
NotIn	such as one value is not part of a list

Member Function Documentation

apply() [1/2]

ConstrainedValue & ConstrainedValue::apply

(

const Constraint &

_constraint

)

Apply a constraint on this value.

Returns

a reference to self

apply() [2/2]

ConstrainedValue & ConstrainedValue::apply	(	const Value &	_value,
		ConstrainedValue::Type	_type )

Apply a constraint on this value, with the given _value and _type.

Returns

a reference to self

hasConstraints()

bool ConstrainedValue::hasConstraints

(

)

const

Returns

true if this constrained value has constrained

update()

cres_qresult< ValueRange > ConstrainedValue::update

(

const ValueRange &

_range

)

Update a range according to the constraint.
