Class InvocationOnWhateverExpression

java.lang.Object
  org.eclipse.xtend.backend.common.ExpressionBase
      org.eclipse.xtend.backend.expr.InvocationOnWhateverExpression

public final class InvocationOnWhateverExpression
extends ExpressionBase

This expression invokes a function on the first argument, deciding at runtime whether to do the "collection magic" of invoking the function on every member of the collection that is the first argument and returning the collection of all the arguments.
This expression does *not* do implicit "this" resolution - it is the responsibility of the initializing code, e.g. in the middle end, to statically resolve that.
