Examples of org.apache.flink.core.io.StringRecord

org.apache.flink.core.io.StringRecord
This class stores text using standard UTF8 encoding. It provides methods to serialize, deserialize, and compare texts at byte level. The type of length is integer and is serialized using zero-compressed format.
In addition, it provides methods for string traversal without converting the byte array to a string.
Also includes utilities for serializing/deserialing a string, coding/decoding a string, checking if a byte array contains valid UTF8 code, calculating the length of an encoded string.
