### Description

This class is deprecated and will be defunct in the next release.

This function is deprecated and will be defunct in the next release.

### Usage

    H5S_source(serverURL, domain, ...)

### Arguments

`serverURL` | a URL for a port for HDF5Server
`domain` | character string with path to file for HSDS
`...` | not used

### Value

an initialized object of type H5S_source

### Slots

`serverURL`

  character string with a URL

`dsmeta`

  DataFrame instance with metadata about content of h5serv server

`dmains`

  DataFrame instance with metadata about the content of hsds server

`getReq`

  DataFrame instance with metadata about hsds server

`folderPath`

  character string with path to user's folder/file on hsds server

### Note

The dsmeta slot holds a DataFrame with a column `dsnames` that is a list with ith element a character vector of all dsnames available for the ith group. There is no effort at present to search all groups for candidate datasets.

If the domain for the HSDS server is known, pass the domain path as a character string along with ther serverURL

### Examples

    ## Not run:
    bigec2 = H5S_source(URL_h5serv()) # h5serv
    bigec2
    dsmeta(bigec2)[1:2,]       # two groups
    dsmeta(bigec2)[1,2][[1]]   # all dataset candidates in group 1
    hsdsCon = H5S_source(URL_hsds()) # hsds server connection
    hsdsCon
    getReq(hsdsCon)
    setPath(hsdsCon,"/home/stvjc/hdf5_mat.h5") -> hsds
    fetchDatasets(hsds)     # grab the dataset id of interest
    H5S_dataset2(hsds, "d-a9e4b71c-8ea2-11e8-9306-0242ac120022")
