            throws java.io.IOException

Description copied from interface: ObjectEncoder

This method will try to encode the given object using the GMLEncoder

Specified by:

encode in interface ObjectEncoder

Parameters:

item - the object to be encoded

enc - an encoder

Throws:

java.io.IOException - in the case of an I/O exception

encodeType

protected java.lang.String encodeType(java.lang.String qualifiedName)

Returns the external form of the given qualified class name.

By default, this method delegates to YGFIOHandler.encode(String).

Note: To prevent obfuscation from breaking user data and style property serialization, an explicit class name encoding should be specified for user data types and style property value types.
