Method Detail

toPredicate

public static Predicate toPredicate(Expression expression)

Converts the given expression into an Predicate

not
```
public static Predicate not(Predicate predicate)
```
A helper method to return the logical not of the given predicate

and

public static Predicate and(Predicate left,
                            Predicate right)

or

public static Predicate or(Predicate left,
                           Predicate right)

Parameters:

predicates - predicates

Returns:

a single predicate containing all the predicates

in
```
public static Predicate in(Predicate... predicates)
```
A helper method to return true if any of the predicates matches.

in
```
public static Predicate in(List<Predicate> predicates)
```
A helper method to return true if any of the predicates matches.
