The bridge pattern can also be thought of as two layers of abstraction. When there is only one fixed implementation, this pattern is known as the Pimpl idiom in the C++ world. The bridge pattern is often confused with the adapter pattern, and is often implemented using the object adapter pattern; e.g., in the Java code below.
public class DebuggingFilter implements Processor {private Processor target; public DebuggingFilter (Processor myTarget) {target = myTarget;} public void execute (ServletRequest req, ServletResponse res) throws IOException, ServletException {//Do some filter processing here, such as // displaying request parameters target. execute (req, res);}}
An example of implementation of this pattern is the javax.servlet.Filter interface, which is part of Java Platform, Enterprise Edition. Aspect-oriented programming (AOP) can also be used in some situations to provide the capability of an interceptor, although AOP doesn't use the elements typically defined [ clarification needed ] for the ...
The critical path of a carry-skip-adder begins at the first full-adder, passes through all adders and ends at the sum-bit .Carry-skip-adders are chained (see block-carry-skip-adders) to reduce the overall critical path, since a single -bit carry-skip-adder has no real speed benefit compared to a -bit ripple-carry adder.
This is a list of the instructions that make up the Java bytecode, an abstract machine language that is ultimately executed by the Java virtual machine. [1] The Java bytecode is generated from languages running on the Java Platform, most notably the Java programming language.
A graph with 16 vertices and six bridges (highlighted in red) An undirected connected graph with no bridge edges. In graph theory, a bridge, isthmus, cut-edge, or cut arc is an edge of a graph whose deletion increases the graph's number of connected components. [1] Equivalently, an edge is a bridge if and only if it is not contained in any cycle.
A snippet of Java code with keywords highlighted in bold blue font. The syntax of Java is the set of rules defining how a Java program is written and interpreted. The syntax is mostly derived from C and C++. Unlike C++, Java has no global functions or variables, but has data members which are also regarded as global variables.
In the Java Swing API, the LayoutManager interface defines how Container objects can have controlled Component placement. One of the more powerful LayoutManager implementations is the GridBagLayout class which requires the use of the GridBagConstraints class to specify how layout control occurs. A typical example of the use of this class is ...
