\title{
Returns a list of child populations of the current node in the \code{GatingHierarchy}
}
\description{
Returns a character vector of all the children of the current node in the \code{GatingHierarchy}
}
\usage{
\S4method{getChildren}{GatingHierarchy,character}(obj, y)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{obj}{
a \code{GatingHierarchy}
}
  \item{y}{
a \code{character} name of the node / population.
}
}
\details{
Get the child nodes / populations of the given node / population, \code{y} in the GatingHierarchy \code{obj}
}
\value{
A \code{character} vector of the names of the child nodes of the current node. An empty vector if the node has no children.
