Method Detail

accessInstanceVariablesDirectly

public static boolean accessInstanceVariablesDirectly()

activateConstraints

public static void activateConstraints(NSArray<? extends NSLayoutConstraint> constraints)

Convenience method that activates each constraint in the contained array, in the same manner as setting active=YES. This is often more efficient than activating each constraint individually.

alloc

public static NSLayoutConstraint alloc()

allocWithZone

public static NSLayoutConstraint allocWithZone(org.moe.natj.general.ptr.VoidPtr zone)

automaticallyNotifiesObserversForKey

public static boolean automaticallyNotifiesObserversForKey(java.lang.String key)

cancelPreviousPerformRequestsWithTarget

                                                                         org.moe.natj.objc.SEL aSelector,
                                                                         java.lang.Object anArgument)

constraintWithItemAttributeRelatedByToItemAttributeMultiplierConstant

public static NSLayoutConstraint constraintWithItemAttributeRelatedByToItemAttributeMultiplierConstant(java.lang.Object view1,
                                                                                                       long attr1,
                                                                                                       long relation,
                                                                                                       java.lang.Object view2,
                                                                                                       long attr2,
                                                                                                       double multiplier,
                                                                                                       double c)

Create constraints explicitly. Constraints are of the form "view1.attr1 = view2.attr2 * multiplier + constant" If your equation does not have a second view and attribute, use nil and NSLayoutAttributeNotAnAttribute. Use of this method is not recommended. Constraints should be created using anchor objects on views and layout guides.

constraintsWithVisualFormatOptionsMetricsViews

public static NSArray<? extends NSLayoutConstraint> constraintsWithVisualFormatOptionsMetricsViews(java.lang.String format,
                                                                                                   long opts,
                                                                                                   NSDictionary<java.lang.String,?> metrics,
                                                                                                   NSDictionary<java.lang.String,?> views)

Create an array of constraints using an ASCII-art-like visual format string. The values of the `metrics` dictionary should be NSNumber (or some other type that responds to -doubleValue and returns a double).

deactivateConstraints

public static void deactivateConstraints(NSArray<? extends NSLayoutConstraint> constraints)

Convenience method that deactivates each constraint in the contained array, in the same manner as setting active=NO. This is often more efficient than deactivating each constraint individually.

debugDescription_static

public static java.lang.String debugDescription_static()

description_static

public static java.lang.String description_static()

hash_static

public static long hash_static()

instanceMethodForSelector

public static NSObject.Function_instanceMethodForSelector_ret instanceMethodForSelector(org.moe.natj.objc.SEL aSelector)

instanceMethodSignatureForSelector

public static NSMethodSignature instanceMethodSignatureForSelector(org.moe.natj.objc.SEL aSelector)

instancesRespondToSelector

public static boolean instancesRespondToSelector(org.moe.natj.objc.SEL aSelector)

isSubclassOfClass

public static boolean isSubclassOfClass(org.moe.natj.objc.Class aClass)

keyPathsForValuesAffectingValueForKey

public static NSSet<java.lang.String> keyPathsForValuesAffectingValueForKey(java.lang.String key)

new_objc

public static NSLayoutConstraint new_objc()

resolveClassMethod

public static boolean resolveClassMethod(org.moe.natj.objc.SEL sel)

resolveInstanceMethod

public static boolean resolveInstanceMethod(org.moe.natj.objc.SEL sel)

setVersion_static

public static void setVersion_static(long aVersion)

superclass_static

public static org.moe.natj.objc.Class superclass_static()

version_static

public static long version_static()

constant

public double constant()

Unlike the other properties, the constant may be modified after constraint creation. Setting the constant on an existing constraint performs much better than removing the constraint and adding a new one that's just like the old but for having a new constant.

firstAnchor

public NSLayoutAnchor<?> firstAnchor()

accessors firstAnchor{==,<=,>=} secondAnchor * multiplier + constant

firstAttribute

public long firstAttribute()

firstItem

public java.lang.Object firstItem()

accessors firstItem.firstAttribute {==,<=,>=} secondItem.secondAttribute * multiplier + constant Access to these properties is not recommended. Use the `firstAnchor` and `secondAnchor` properties instead.

identifier

public java.lang.String identifier()

For ease in debugging, name a constraint by setting its identifier, which will be printed in the constraint's description. Identifiers starting with NS or UI are reserved by the system.

init

public NSLayoutConstraint init()

Overrides:

init in class NSObject

isActive

public boolean isActive()

The receiver may be activated or deactivated by manipulating this property. Only active constraints affect the calculated layout. Attempting to activate a constraint whose items have no common ancestor will cause an exception to be thrown. Defaults to NO for newly created constraints.

setActive

public void setActive(boolean value)

The receiver may be activated or deactivated by manipulating this property. Only active constraints affect the calculated layout. Attempting to activate a constraint whose items have no common ancestor will cause an exception to be thrown. Defaults to NO for newly created constraints.

multiplier

public double multiplier()

priority

public float priority()

relation

public long relation()

secondAnchor

public NSLayoutAnchor<?> secondAnchor()

secondAttribute

public long secondAttribute()

secondItem

public java.lang.Object secondItem()

setConstant

public void setConstant(double value)

Unlike the other properties, the constant may be modified after constraint creation. Setting the constant on an existing constraint performs much better than removing the constraint and adding a new one that's just like the old but for having a new constant.

setIdentifier

public void setIdentifier(java.lang.String value)

For ease in debugging, name a constraint by setting its identifier, which will be printed in the constraint's description. Identifiers starting with NS or UI are reserved by the system.

setPriority

public void setPriority(float value)

setShouldBeArchived

public void setShouldBeArchived(boolean value)

When a view is archived, it archives some but not all constraints in its -constraints array. The value of shouldBeArchived informs the view if a particular constraint should be archived by the view. If a constraint is created at runtime in response to the state of the object, it isn't appropriate to archive the constraint - rather you archive the state that gives rise to the constraint. Since the majority of constraints that should be archived are created in Interface Builder (which is smart enough to set this prop to YES), the default value for this property is NO.

shouldBeArchived

public boolean shouldBeArchived()

When a view is archived, it archives some but not all constraints in its -constraints array. The value of shouldBeArchived informs the view if a particular constraint should be archived by the view. If a constraint is created at runtime in response to the state of the object, it isn't appropriate to archive the constraint - rather you archive the state that gives rise to the constraint. Since the majority of constraints that should be archived are created in Interface Builder (which is smart enough to set this prop to YES), the default value for this property is NO.
