Everything starts from the words from the ScratchPad (Specification). Here, the scratchpad I want to say is an agreement that is used to obtain binary from the network or the local input stream and localize the data. To mention this, you must first introduce the source of this agreement.
"DoJA is NTT Docomo Java application profile for its I-Mode service. It runs on the J2ME CLDC API."
"DoJA application can store data generated in the application and data downloaded from the network to the mobile terminal. This feature is called scratchpad."
The syntax of the protocol complies with General Connection Framework, is simple to say is factory model. Use the Connector to create a connection, which correspond to different data exchange protocols. They all use the interface defined by the universal connection framework to implement functionality. The connection parameters of this connection framework are specified by the protocol itself, and the connection string is required when defined, and the resolution is completed by the server. This connection string can be referred to RFC 2396. Below is a description:
The Parameter String That Describes The Target Should Conformed in Url Format As Described in RFC 2396. This Takes The General Form:
{scheme}: [{target}] [{parms}]
WHERE {scheme} is the name of a protocol such as http}.
The {target} is Normally Some Kind of Network Address.
ANY {Parms} Are Formed AS A Series of Equates of the form "; x = y". EXAMPLE: "; TYPE = a".
The method of achieving localization with the corresponding MIDP is to use the RMS storage manager. This manager is certain than the CLDC level API. It is best to personally realize the storage management of ScratchPad, on the one hand, as a target, on the one hand, can better understand the API in java.io defined in CLDC. These APIs are interactive with mobile extension javax.microedition.IO to complete the data interaction of mobile platform applications. Of course, the RMS extension in the MIDP or the IO extension of DoCoMo in DoJA may have a very convenient API. But the BYTE level data control has a large use of space because it is open (original).
My main purpose is to "依 葫 画 画 画", is the special function of the application according to its own use of the high-level interface.
This is very simple, just to learn.
