/**
 * Class Pattern
 *
 * A pattern is used to fill or stroke an object using a pre-defined graphic object which can be replicated ("tiled")
 * at fixed intervals in x and y to cover the areas to be painted. Patterns are defined using a 'pattern' element and
 * then referenced by properties 'fill' and 'stroke' on a given graphics element to indicate that the given element
 * shall be filled or stroked with the referenced pattern.
 *
 * @link    https://www.w3.org/TR/SVG/pservers.html#Patterns
 * @property string patternUnits        "userSpaceOnUse | objectBoundingBox" Defines the coordinate system for
 *           attributes 'x',
 *           'y', 'width' and 'height'. If patternUnits="userSpaceOnUse", 'x', 'y', 'width' and 'height' represent
 *           values in the coordinate system that results from taking the current user coordinate system in place at
 *           the time when the 'pattern' element is referenced (i.e., the user coordinate system for the element
 *           referencing the 'pattern' element via a 'fill' or 'stroke' property) and then applying the transform
 *           specified by attribute 'patternTransform'. If patternUnits="objectBoundingBox", the user coordinate system
 *           for attributes 'x', 'y', 'width' and 'height' is established using the bounding box of the element to
 *           which the pattern is applied (see Object bounding box units) and then applying the transform specified by
 *           attribute 'patternTransform'. If attribute 'patternUnits' is not specified, then the effect is as if a
 *           value of 'objectBoundingBox' were specified.
 * @property string patternContentUnits = "userSpaceOnUse | objectBoundingBox" Defines the coordinate system for the
 *           contents of the ‘pattern’. Note that this attribute has no effect if attribute ‘viewBox’ is specified. If
 *           patternContentUnits="userSpaceOnUse", the user coordinate system for the contents of the ‘pattern’ element
 *           is the coordinate system that results from taking the current user coordinate system in place at the time
 *           when the ‘pattern’ element is referenced (i.e., the user coordinate system for the element referencing the
 *           ‘pattern’ element via a ‘fill’ or ‘stroke’ property) and then applying the transform specified by
 *           attribute ‘patternTransform’. If patternContentUnits="objectBoundingBox", the user coordinate system for
 *           the contents of the ‘pattern’ element is established using the bounding box of the element to which the
 *           pattern is applied (see Object bounding box units) and then applying the transform specified by attribute
 *           ‘patternTransform’. If attribute ‘patternContentUnits’ is not specified, then the effect is as if a value
 *           of 'userSpaceOnUse' were specified.
 * @property string patternTransform    = "<transform-list>" Contains the definition of an optional additional
 *           transformation from the pattern coordinate system onto the target coordinate system (i.e.,
 *           'userSpaceOnUse' or 'objectBoundingBox'). This allows for things such as skewing the pattern tiles. This
 *           additional transformation matrix is post-multiplied to (i.e., inserted to the right of) any previously
 *           defined transformations, including the implicit transformation necessary to convert from object bounding
 *           box units to user space. If attribute ‘patternTransform’ is not specified, then the effect is as if an
 *           identity transform were specified.
 * @property float  x                   = "<coordinate>" ‘x’, ‘y’, ‘width’ and ‘height’ indicate how the pattern tiles
 *           are placed and spaced. These attributes represent coordinates and values in the coordinate space specified
 *           by the combination of attributes ‘patternUnits’ and ‘patternTransform’. If the attribute is not specified,
 *           the effect is as if a value of zero were specified.
 * @property float  y                   = "<coordinate>" See ‘x’. If the attribute is not specified, the effect is as
 *           if a value of zero were specified.
 * @property float  width               = "<length>" See ‘x’. A negative value is an error (see Error processing). A
 *           value of zero disables rendering of the element (i.e., no paint is applied). If the attribute is not
 *           specified, the effect is as if a value of zero were specified.
 * @property float  height              = "<length>" See ‘x’. A negative value is an error (see Error processing). A
 *           value of zero disables rendering of the element (i.e., no paint is applied). If the attribute is not
 *           specified, the effect is as if a value of zero were specified.
 * @property float  xlink               :href = "<iri>" An IRI reference to a different ‘pattern’ element within the
 *           current SVG document fragment. Any attributes which are defined on the referenced element which are not
 *           defined on this element are inherited by this element. If this element has no children, and the referenced
 *           element does (possibly due to its own ‘xlink:href’ attribute), then this element inherits the children
 *           from the referenced element. Inheritance can be indirect to an arbitrary level; thus, if the referenced
 *           element inherits attributes or children due to its own ‘xlink:href’ attribute, then the current element
 *           can inherit those attributes or children.

How about adding an `instanceof` check? If you access a property on an interface, you most likely code against a concrete implementation of the interface. Available Fixes Adding an additional type check: interface SomeInterface { } class SomeClass implements SomeInterface { public $a; } function someFunction(SomeInterface $object) { if ($object instanceof SomeClass) { $a = $object->a; } } Changing the type hint: interface SomeInterface { } class SomeClass implements SomeInterface { public $a; } function someFunction(SomeClass $object) { $a = $object->a; } Loading history...
