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 useClass.getComponentTypewhile the result is an array and then check the class. TheserialClass is nullin 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 at1and 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:
streamBytesis 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
