Method Detail

$q

public static <T> List<T> $q(List<T> list,
             Class<?>... classes)

$q turns a listStream into a querying listStream.

Type Parameters:

T - The type this criteria listStream will return

Parameters:

list - the listStream you want to convert

classes - classes you want to be able to criteria.

Returns:

generic listStream decorated with criteria features.

$c

public static <T> List<T> $c(List<T> list)

$c turns a listStream back into a regular listStream. This is the reverse of $q.

Type Parameters:

T - the type of the listStream.

Parameters:

list - the listStream

Returns:

the new decorated listStream.

plainList(java.util.List)

listQuery

public static <T> List<T> listQuery(List<T> list)

listQuery turns a listStream into a querying listStream.

Type Parameters:

T - The type this criteria listStream will return

Parameters:

list - the listStream you want to convert

Returns:

generic listStream decorated with criteria features.

See Also:

$q(java.util.List, Class[])

listQuery

public static <T> List<T> listQuery(List<T> list,

                    boolean useUnSafe,
                    Class<?>... classes)

listQuery turns a listStream into a querying listStream.

Type Parameters:

T - The type this criteria listStream will return

Parameters:

list - the listStream you want to convert

classes - classes you want to be able to criteria.

useField - use the field instead of the property

useUnSafe - use unsafe
