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

Example 1 with AssignmentStatementNode

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

the class BallerinaPsiImplUtil method findStructDefinition.

/**
 * Resolves the corresponding struct definition of the provided identifier node if possible.
 * Eg:
 * <pre>
 * function main (string[] args) {
 *     var person = getData();
 *     var person2 = person;
 *     var person3 = person2;
 *
 *     system:println(person3.&lt;caret&gt;);
 * }
 *
 * function getData () (Person) {
 *     Person person = {name:"Shan", age:26};
 *     return person;
 * }
 *
 * struct Person {
 *    string name;
 *    int age;
 * }
 * </pre>
 * <p>
 * From the above caret position, we should be able to get the type of the 'person3'. So we resolve recursively
 * until we find the struct definition. If the RHS has a variable, we resolve the definition of the variable and
 * call this method again. So in the first call of this function, 'resolvedElement' will be the
 * definition of 'person3'. Next, the definition of 'person2' and definition of 'person' after that. At that point,
 * we find a function invocation in the RHS. So we get the type from that.
 *
 * @param resolvedElement element which was resolved from the variable reference
 * @return corresponding {@link StructDefinitionNode} if the structName can be resolved, {@code null} otherwise.
