Class MemoryMeter.Builder

Method Details

• build

  public MemoryMeter build()

• withGuessing

  public MemoryMeter.Builder withGuessing(MemoryMeter.Guess strategy, MemoryMeter.Guess... fallbacks)

  Specify what should be the strategy used to measure the shallow size of object.

  Parameters:

  strategy - the strategy that should be used to measure objects

  fallbacks - the fallback strategies

  Returns:

  this builder

• ignoreOuterClassReference

  public MemoryMeter.Builder ignoreOuterClassReference()

  Ignores the outer class reference from non-static inner classes.

  In practice this is only useful if the top class provided to MemoryMeter.measureDeep is an inner class and we wish to ignore the outer class in the measurement.

  Returns:

  this builder

• measureKnownSingletons

  public MemoryMeter.Builder measureKnownSingletons()

  Measures the space occupied by known singletons such as Class objects, enums, ClassLoaders and AccessControlContexts. By default MemoryMeter will ignore those.

  Returns:

• measureNonStrongReferences

  public MemoryMeter.Builder measureNonStrongReferences()

  Measures the references from a Reference (like weak/soft/phantom references). By default MemoryMeter will ignore those.

  Returns:

  this builder

• printVisitedTree

  public MemoryMeter.Builder printVisitedTree()

  Prints the classes tree to System.out when measuring through measureDeep.

  Returns:

  this builder

• printVisitedTreeUpTo

  public MemoryMeter.Builder printVisitedTreeUpTo(int depth)

  Prints the classes tree to System.out up to the specified depth when measuring through measureDeep.

  Parameters:

  depth - the depth up to which the class tree must be printed

  Returns:

  this builder
