Method Detail

beforeSearch

protected SearchRequest beforeSearch(SearchRequest pRequest,
                         atg.search.client.SearchSession pSession)

When using saveRequest (see SearchRequest.setSaveRequest(boolean)), if this is a paging request this method will replace the current request with the last one, and update it to reflect the correct page number. If this is not a paging request this method ensures that any previously-saved page number is cleared from the SearchSession.

Overrides:

beforeSearch in class BaseSearchFormHandler

Parameters:

pRequest - current search request

pSession - search session

Returns:

the passed-in request, or the previous request with an updated page number and chain token

getPagesAvailable

public int getPagesAvailable()

Returns the number of available pages based on the type of paging, page size, and total results. It will always be >= 1. If Fast paging is disabled (the default; see PagedRequest.setFastPaging(Boolean)), this is the number of pages available; if Fast paging is enabled, this is the number of pages visited so far.

Returns:

number of available pages of answers based on the type of paging and page size and total results, always >= 1

getGoToPage

public java.lang.Integer getGoToPage()

The 1-based page that will be retrieved next, or that has already been retrieved.

Returns:

The 1-based page

setGoToPage

public void setGoToPage(java.lang.Integer pPageNum)

Sets the 1-based page that will be retrieved next. This sets the page number on the session and request.

Parameters:

pPageNum - The 1-based page number.

See Also:

handleGoToPage(atg.servlet.DynamoHttpServletRequest, atg.servlet.DynamoHttpServletResponse)

handleGoToPage

public boolean handleGoToPage(DynamoHttpServletRequest pRequest,
                     DynamoHttpServletResponse pResponse)
                       throws javax.servlet.ServletException,
                              java.io.IOException

Called when user is iterating through pages of results.

Parameters:

pRequest - the servlet's request

pResponse - the servlet's response

Returns:

false to stop form processing

Throws:

javax.servlet.ServletException - if there was an error while executing the code

java.io.IOException - if there was an error with servlet io
