jdeserialize

Interface content

All Known Implementing Classes:

arrayobj, blockdata, classdesc, classobj, contentbase, enumobj, exceptionstate, instance, stringobj

public interface content

Generic interface for all data that may be read from the stream (except null).

A successful read of the stream will result in a series of content instances or null references. For details on specific metadata, see documentation on implementing classes/subinterfaces.

Method Detail

getType

contenttype getType()

Returns:

the type of instance represented by this object.

getHandle

int getHandle()

Get the numeric handle by which this object was referred to in the object stream. These handles are used internally by Object{Output,Input}Stream as a mechanism to avoid costly duplication.

CAUTION: they are *not* necessarily unique across all objects in a given stream! If an exception was thrown during serialization (which is most likely to happen during a serialized objct's writeObject() implementation), then the stream resets before and after the exception is serialized.

Returns:

the handle assigned in the stream

validate

void validate()
       throws ValidityException

Performs extra object-specific validity checks.

Throws:

ValidityException - if the object's state is invalid

isExceptionObject

boolean isExceptionObject()

Tells whether or not this object is an exception that was caught during serialization.

Note: Not every Throwable or Exception in the stream will have this flag set to true; only those which were thrown during serialization will

Returns:

true iff the object was an exception thrown during serialization

setIsExceptionObject

void setIsExceptionObject(boolean value)

Sets the flag that tells whether or not this object is an exception that was caught during serialization.

Parameters:

value - the new value to use

toJson

java.lang.String toJson(java.lang.String indentation,
                        java.util.Map<classdesc,java.util.Map<field,java.lang.Object>> fielddata,
                        boolean child)

Analogy for toString method; however, outputs its string in json formatting. Returns the exact json representation of object with indentation.

Inherited by multiple classes via contentbase, often calls itself for another object

Parameters:

indentation - starting indentation for json output

fielddata - used when calling this method for inner instances so the instance has info about its variables. Instance info is saved in another content space than info about its field variables, so it must be provided by parameter to inner instances

child - tells that the instance is child of another because of indentation

Returns:

The string in json format representing this instance
