Method Details

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.getComponentType
while the result is an array and then check the class. TheserialClass 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 at1
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
