Factory method pattern. In object-oriented programming, the factory method pattern is a design pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact classes. Rather than by calling a constructor, this is accomplished by invoking a factory method to create an object.
Al Held (October 12, 1928 – July 27, 2005) was an American Abstract expressionist painter.He was particularly well known for his large scale Hard-edge paintings. [1] As an artist, multiple stylistic changes occurred throughout his career, however, none of these occurred at the same time as any popular emerging style or acted against a particular art form. [2]
Abstract art uses visual language of shape, form, color and line to create a composition which may exist with a degree of independence from visual references in the world. [ 1 ] Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective and an attempt to reproduce an illusion of ...
Software design pattern. In software engineering, a design pattern is describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code. Using a pattern is intended to leverage an existing concept rather than re-inventing it. This can decrease the time to develop software and increase ...
A wallpaper group (or plane symmetry group or plane crystallographic group) is a mathematical classification of a two-dimensional repetitive pattern, based on the symmetries in the pattern. Such patterns occur frequently in architecture and decorative art, especially in textiles, tiles, and wallpaper. The simplest wallpaper group, Group p 1 ...
In situations where a character's life events flash across his/her mind, a splash page may be used with the entire background consisting of segments from earlier chapters. Abstract background effects: These involve elaborate hatching patterns in the background and serve to indicate or strengthen the mood of the plot. It can also illustrate a ...
Abstract algebra. The permutations of the Rubik's Cube form a group, a fundamental concept within abstract algebra. In mathematics, more specifically algebra, abstract algebra or modern algebra is the study of algebraic structures, which are sets with specific operations acting on their elements. [1] Algebraic structures include groups, rings ...
A pattern is a regularity in the world, in human-made design, [1] or in abstract ideas. As such, the elements of a pattern repeat in a predictable manner. A geometric pattern is a kind of pattern formed of geometric shapes and typically repeated like a wallpaper design. Any of the senses may directly observe patterns.
