• helperMemoryUse

  public Map<String,Long> helperMemoryUse()

  Description copied from interface: LayerHelper
  Return the currently allocated memory for the helper.
  (a) Excludes: any shared memory used by multiple helpers/layers
  (b) Excludes any temporary memory (c) Includes all memory that persists for longer than the helper method
  This is mainly used for debugging and reporting purposes. Returns a map:
  Key: The name of the type of memory
  Value: The amount of memory
  

  Specified by:

  helperMemoryUse in interface LayerHelper

  Returns:

  Map of memory, may be null if none is used.
