class TAS3File: public TWebFile


TAS3File

A TAS3File is a normal TWebFile but it reads data from the
Amazon S3 server. As a derived TWebFile class TAS3File it is a
read only file. The HTTP requests are generated by THTTPMessage
objects with the auth_prefix set as AWS. The user id and secret pass
required to sign the requests are passed through the environment
variables S3_ACCESS_ID and S3_ACCESS_KEY.
For more information check:

Function documentation

TAS3File(const char* url, Option_t* opt = "")
 For TAS3File to properly work you need to set up
 environment variables S3_ACCESS_ID and S3_ACCESS_KEY
 The format of the path is: server/bucket/file
 Example: f = new TAS3File("as3://s3-eu-west-1.amazonaws.com/roots3/hsimple.root")
Int_t GetHead()
 Clone of TWebFile::GetHead except it uses THTTPMessage to generate
 the HTTP request.
Bool_t ReadBuffer(char* buf, Int_t len)
Bool_t ReadBuffer10(char* buf, Int_t len)
 Read specified byte range from Amazon S3.
 This routine connects to the Amazon S3 server, sends the
 request created by THTTPMessage and returns the buffer.
 Returns kTRUE in case of error.
