Java Module java.base Package java.io Interface ObjectInputFilter.FilterInfo（JDK11）

Method Detail

• serialClass

  Class<?> serialClass()

  The class of an object being deserialized. For arrays, it is the array type. For example, the array class name of a 2 dimensional array of strings is "[[Ljava.lang.String;". To check the array's element type, iteratively use Class.getComponentType while the result is an array and then check the class. The serialClass is null in the case where a new object is not being created and to give the filter a chance to check the depth, number of references to existing objects, and the stream size.

  Returns:

  class of an object being deserialized; may be null

• arrayLength

  long arrayLength()

  The number of array elements when deserializing an array of the class.

  Returns:

  the non-negative number of array elements when deserializing an array of the class, otherwise -1

• depth

  long depth()

  The current depth. The depth starts at 1 and increases for each nested object and decrements when each nested object returns.

  Returns:

  the current depth

• references

  long references()

  The current number of object references.

  Returns:

  the non-negative current number of object references

• streamBytes

  long streamBytes()

  The current number of bytes consumed.

  Implementation Requirements:

  streamBytes is implementation specific and may not be directly related to the object in the stream that caused the callback.

  Returns:

  the non-negative current number of bytes consumed
