All Implemented Interfaces:

IDataComposer

public class DataComposerCipher
extends DataComposerMemory

It generates the states of each page storing them in the client. These states will be encoded to guarantee its integrity.

Non editable values are hidden to the client to guarantee confidentiality confidentiality.

public DataComposerCipher()

Method Detail

endRequest

public java.lang.String endRequest()

It is called by each request or form existing in the page returned by the server.

it generates an encoded string containing the current state.

If the size of the generated state exceeds the maximun length allowed allowedLength the Memory strategy will be used, adding the state of the request or form to the page page and returning an identifier composed by the page identifier and the state identifier as a result.

Specified by:

endRequest in interface IDataComposer

Overrides:

endRequest in class DataComposerMemory

Returns:

String with the encoded state. If the Memory strategy has been used, an identifier.

endPage

public void endPage()

Only if the generated encoded state exceeds the maximun length allowed it will be necessary to store in session the object representing the current page.

Specified by:

endPage in interface IDataComposer

Overrides:

endPage in class DataComposerMemory

See Also:

DataComposerMemory.endPage()

startPage

public void startPage()

Description copied from class: DataComposerMemory

It is called in the pre-processing stage of each user request assigning a new page identifier to the page.

Specified by:

startPage in interface IDataComposer

Overrides:

startPage in class DataComposerMemory

getEncodingUtil

public EncodingUtil getEncodingUtil()

Returns:

Returns the encoding util.

setEncodingUtil

public void setEncodingUtil(EncodingUtil encodingUtil)

Parameters:

encodingUtil - The encoding util to set.

setAllowedLength

public void setAllowedLength(int allowedLength)

Parameters:

allowedLength - The allowed length to set.
