## get gated flow data from a GatingHierarchy/GatingSet/GatingSetList

### Description

get gated flow data from a GatingHierarchy/GatingSet/GatingSetList

### Usage

    ## S4 method for signature 'GatingHierarchy,missing'
    getData(obj, y, ...)

    ## S4 method for signature 'GatingHierarchy,character'
    getData(obj, y, ...)

    ## S4 method for signature 'GatingSet,missing'
    getData(obj, y, ...)

    ## S4 method for signature 'GatingSet,character'
    getData(obj, y, ...)

    ## S4 method for signature 'GatingSetList,ANY'
    getData(obj, y, ...)

### Arguments

`obj` | A `GatingHierarchy`, `GatingSet` or `GatingSetList` object.
`y` | `character` the node name or full(/partial) gating path. If not specified, will return the complete flowFrame/flowSet at the root node.
`...` | arguments passed to ncdfFlow::[[

### Details

Returns a flowFrame/flowSet containing the events in the gate defined at node `y`. Subset membership can be obtained using `getIndices`. Population statistics can be obtained using `getPop` and `getPopStats`. When calling `getData` on a GatingSet,the trees representing the GatingHierarchy for each sample in the GaingSet are presumed to have the same structure. To update the data, use `flowData` method.

### Value

A `flowFrame` object if `obj` is a GatingHierarchy. A `flowSet` or `ncdfFlowSet` if a `GatingSet`. A `ncdfFlowList` if a `GatingSetList`.

### See Also

`flowData` `getIndices` `getPopStats`

### Examples

      ## Not run:
        #G is a GatingSet
        geData(G,3) #get a flowSet constructed from the third node / population in the tree.
        geData(G,"cd4")

        #gh is a GatingHierarchy
        getData(gh)

    ## End(Not run)
