Examples with ParameterTypeName org.ballerinalang.plugins.idea.psi.ParameterTypeName used on opensource projects

Example 1 with ParameterTypeName

use of org.ballerinalang.plugins.idea.psi.ParameterTypeName in project ballerina by ballerina-lang.

the class BallerinaDocumentationProvider method getReturnTypes.

/**
 * Returns the return types of the given definition node. This return types are later used to generate the
 * signature.
 *
 * @param definitionNode definition node which we want to get the return types
 * @return list of return type strings.
 */
private static List<String> getReturnTypes(PsiElement definitionNode) {
    List<String> results = new LinkedList<>();
    // Parameters are in the ReturnParameterNode. So we first get the ReturnParameterNode from the definition
    // node.
    ReturnParameterNode node = PsiTreeUtil.findChildOfType(definitionNode, ReturnParameterNode.class);
    if (node == null) {
        return results;
    }
    // But there can be two possible scenarios. The actual return types can be in either ParameterTypeNameList or
    // ParameterListNode. This is because return types can be named parameters. In that case, ParameterListNode is
    // available.
    // First we check for ParameterTypeNameList.
    ParameterTypeNameList parameterTypeNameList = PsiTreeUtil.findChildOfType(node, ParameterTypeNameList.class);
    // If it is available, that means the return types are not named parameters.
    if (parameterTypeNameList != null) {

            }
        });
        // Return the results.
        return results;
    }
    // If there is no return type node, we check for ParameterListNode.
    ParameterListNode parameterListNode = PsiTreeUtil.findChildOfType(node, ParameterListNode.class);
    if (parameterListNode != null) {
        // Actual parameters are in ParameterNodes.
        Collection<ParameterNode> parameterNodes = PsiTreeUtil.findChildrenOfType(parameterListNode, ParameterNode.class);
        // Add each ParameterNode to the result list.

        // Return the results.
        return results;
    }
    // Return empty list.
    return results;
