Parameter

parent

string

Required. The session to list all session entity types from. Format: projects/<Project ID>/agent/sessions/<Session ID>.

pageSize

Optional

number

The maximum number of resources contained in the underlying API response. If page streaming is performed per-resource, this parameter does not affect the return value. If page streaming is performed per-page, this determines the maximum number of resources in a page.

The second parameter to the callback is Array of SessionEntityType.

When autoPaginate: false is specified through options, it contains the result in a single response. If the response indicates the next page exists, the third parameter is set to be used for the next request object. The fourth parameter keeps the raw response object of an object representing ListSessionEntityTypesResponse.

Returns

Promise 

  • The promise which resolves to an array. The first element of the array is Array of SessionEntityType.

    When autoPaginate: false is specified through options, the array has three elements. The first element is Array of SessionEntityType in a single response. The second element is the next request object if the response indicates the next page exists, or null. The third element is an object representing ListSessionEntityTypesResponse.

    The promise has a method named "cancel" which cancels the ongoing API call.

Example

const dialogflow = require('dialogflow');

const client = new dialogflow.v2.SessionEntityTypesClient({
  // optional auth parameters.
});

// Iterate over all elements.
const formattedParent = client.sessionPath('[PROJECT]', '[SESSION]');

client.listSessionEntityTypes({parent: formattedParent})
  .then(responses => {
    const resources = responses[0];
    for (const resource of resources) {
      // doThingsWith(resource)
    }
  })
  .catch(err => {
    console.error(err);
  });

// Or obtain the paged response.
const formattedParent = client.sessionPath('[PROJECT]', '[SESSION]');


const options = {autoPaginate: false};
const callback = responses => {
  // The actual resources in a response.
  const resources = responses[0];
  // The next request if the response shows that there are more responses.
  const nextRequest = responses[1];
  // The actual response object, if necessary.
  // const rawResponse = responses[2];
  for (const resource of resources) {
    // doThingsWith(resource);
  }
  if (nextRequest) {
    // Fetch the next page.
    return client.listSessionEntityTypes(nextRequest, options).then(callback);
  }
}
client.listSessionEntityTypes({parent: formattedParent}, options)
  .then(callback)
  .catch(err => {
    console.error(err);
  });
