InitializeTableFromTextFile

public final class InitializeTableFromTextFile

Initializes a table from a text file.

It inserts one key-value pair into the table for each line of the file. The key and value is extracted from the whole line content, elements from the split line based on `delimiter` or the line number (starting from zero). Where to extract the key and value from a line is specified by `key_index` and `value_index`.

- A value of -1 means use the line number(starting from zero), expects `int64`. - A value of -2 means use the whole line content, expects `string`. - A value >= 0 means use the index (starting at zero) of the split line based on `delimiter`.
