Binding.hasVariable介绍

[英]Simple check for whether the binding contains a particular variable or not.
[中]简单检查绑定是否包含特定变量。

代码示例

代码示例来源：origin: spring-projects/spring-framework

if (binding != null && binding.hasVariable(name)) {
  return binding.getVariable(name);

代码示例来源：origin: org.springframework/spring-beans

if (binding != null && binding.hasVariable(name)) {
  return binding.getVariable(name);

代码示例来源：origin: io.snamp/scripting

/**
 * Simple check for whether the binding contains a particular variable or not.
 *
 * @param name the name of the variable to check for
 */
@Override
public boolean hasVariable(final String name) {
  return first.hasVariable(name) && second.hasVariable(name);

/**
 * @param name the name of the variable to lookup
 * @return the variable value
 */
