getVisitorId

public String getVisitorId()

 Required. A unique identifier for tracking visitors.

 For example, this could be implemented with an HTTP cookie, which should be
 able to uniquely identify a visitor on a single device. This unique
 identifier should not change if the visitor log in/out of the website.

 Don't set the field to the same fixed ID for different users. This mixes
 the event history of those users together, which results in degraded model
 quality.

 The field must be a UTF-8 encoded string with a length limit of 128
 characters. Otherwise, an INVALID_ARGUMENT error is returned.

 The field should not contain PII or user-data. We recommend to use Google
 Analytics [Client
 ID](https://developers.google.com/analytics/devguides/collection/analyticsjs/field-reference#clientId)
 for this field.

string visitor_id = 2 [(.google.api.field_behavior) = REQUIRED];

Specified by:: getVisitorId in interface UserEventOrBuilder
Returns:: The visitorId.

getVisitorIdBytes

public com.google.protobuf.ByteString getVisitorIdBytes()

 Required. A unique identifier for tracking visitors.

 For example, this could be implemented with an HTTP cookie, which should be
 able to uniquely identify a visitor on a single device. This unique
 identifier should not change if the visitor log in/out of the website.

 Don't set the field to the same fixed ID for different users. This mixes
 the event history of those users together, which results in degraded model
 quality.

 The field must be a UTF-8 encoded string with a length limit of 128
 characters. Otherwise, an INVALID_ARGUMENT error is returned.

 The field should not contain PII or user-data. We recommend to use Google
 Analytics [Client
 ID](https://developers.google.com/analytics/devguides/collection/analyticsjs/field-reference#clientId)
 for this field.

string visitor_id = 2 [(.google.api.field_behavior) = REQUIRED];
