Method Detail

addClauses

public void addClauses(java.lang.String use,
                       java.lang.String structure,
                       java.lang.String relation,
                       java.lang.String line,
                       java.lang.String concordancia,
                       java.lang.String operator)

It adds a new clause to the query

Parameters:

use - It is a number that represent an attribute (4=Title,62=abstract,...)

structure - It defines the attribute type (1=Phrase,2=wors,...)

relation - Relation between the attribute and the query (1=LessThan,3=equal,...)

line - String with the user introduced value

concordancia - Relationship between different words of the same field (more than one words) E,A o Y --> Exact, All, anY

operator - Relationship between fields (title, abstract) 'and' or 'or'

addClauses

public void addClauses(java.lang.String use,
                       java.lang.String structure,
                       java.lang.String relation,
                       java.util.Iterator values,
                       java.lang.String concordancia,
                       java.lang.String operator)

It realize the same function than the "addClauses(String use, String structure String relation,String line, String concordancia)" function, but the words to find are in a vector.

Parameters:

use -

structure -

relation -

values -

concordancia -

operator -

addCurrentClauseQuery

protected void addCurrentClauseQuery(java.lang.String operator)

It adds a new query to the current query.

Parameters:

operator - 'and' or 'or'. Relation between fields

toString

public java.lang.String toString(java.lang.String database)

It returns the complete BER query

Returns:
