Daniel Sun updated GROOVY-8258:
-------------------------------
Description:
h2. *Ⅰ. Introduction*
GINQ DSL is an alternative solution of GINQ, it is a simplified version of
GINQ(GROOVY-9159) and will be implemented as a module "groovy-linq".
GINQ DSL is wrapped with:
{code:java}
ginq {
// GINQ code
}
{code}
h2. *Ⅱ. Sample code related to GROOVY-9159*
h4. 1.1
{code:java}

where p.age > 15 && p.age <= 35
select p.name
