How PMD Apex Rules work

Sample Rule: Method names should not contain underscores

• PMD gets method Name: String methodName = node.getImage();

• Checks the methodName for starting-with-capital-letters

• Checks for the '_' in the methodName

• CODECLIMATE_CATEGORIES for this issue: 'Style'

• Refer: MethodNamingConventionsRule

public Object visit(ASTMethod node, Object data) {
  		if (isOverriddenMethod(node) || isPropertyAccessor(node) || isConstructor(node)) {
  			return data;
  		}
  
  		String methodName = node.getImage();
  
  		if (Character.isUpperCase(methodName.charAt(0))) {
  			addViolationWithMessage(data, node, "Method names should not start with capital letters");
  		}
  		if (methodName.indexOf('_') >= 0) {
  			addViolationWithMessage(data, node, "Method names should not contain underscores");
  		}
  		return data;
 }
