public com.ds.fw.dv.search.FwDVSearchQuery bulid(java.lang.String s1)

This methods build a framework query object from a string.

Parameters:

s1 - the string to be parsed

Returns:

the query

strReplace

public java.lang.String strReplace(java.lang.String sOld,
                                   java.lang.String sNew,

This method replaces all substrings of a string, metching a given string.

Parameters:

sOld - substring to be replaced

sNew - the new substring to be placed

s - the main string

Returns:

a new edited string

fixQuery

public java.lang.String fixQuery(java.lang.String s)

Fixes the string which will be parsed to produse a query. (i.e. replaces all double separators with single ones)

Parameters:

s - the string to be fixed

Returns:

Parameters:

s - the string to be fixed

Returns:

a new fixed string

stringCorrect

public java.lang.String stringCorrect(java.lang.String s)

Replaces default separator in a quoted substring of a string with other special simbol(s) (i.e "^^").
