getTransactionByHash function is not available in the go-ethereum package

Question

In have downloaded go-ethereum package and made the private network. I am able to make changes in the code as per my requirement and it is also working fine. However, ethereum_js.go file has the following lines

    var getTransaction = new Method({
    name: 'getTransaction',
    call: 'eth_getTransactionByHash',
    params: 1,
    outputFormatter: formatters.outputTransactionFormatter
    });

Above says whenever we use getTransaction, it call eth_getTransactionByHash.

But there is no function avaialable with name getTransactionByHash.

Also the following line is not clear

         outputFormatter: formatters.outputTransactionFormatter

Here's a full example of using the TransactionByHash method from the go-ethereum client package.

package main

import (
    "context"
    "fmt"
    "log"

    "github.com/ethereum/go-ethereum/common"
    "github.com/ethereum/go-ethereum/ethclient"
)

func main() {
    client, err := ethclient.Dial("https://mainnet.infura.io")
    if err != nil {
        log.Fatal(err)
    }

    txHash := common.HexToHash("0x5d49fcaa394c97ec8a9c3e7bd9e8388d420fb050a52083ca52ff24b3b65bc9c2")
    tx, isPending, err := client.TransactionByHash(context.Background(), txHash)
    if err != nil {
        log.Fatal(err)
    }

    fmt.Println(tx.Hash().Hex())     // 0x5d49fcaa394c97ec8a9c3e7bd9e8388d420fb050a52083ca52ff24b3b65bc9c2
    fmt.Println(tx.Value().String()) // 10000000000000000 (in wei)
    fmt.Println(isPending)           // false
}
