Method Detail

matches

public final boolean matches(java.lang.Object content)
Description copied from interface: Filter
Check to see if the object matches a predefined set of rules.

Specified by:
matches in interface Filter<T>
Parameters:
content - The object to verify.
Returns:
true if the object matches a predfined set of rules.

filter

public java.util.List<T> filter(java.util.List<?> content)
Description copied from interface: Filter
Filter the input list keeping only the items that match the Filter.

Specified by:
filter in interface Filter<T>
Parameters:
content - The content to filter.
Returns:
a new read-only RandomAccess list of the filtered input content.

negate

public final Filter<?> negate()
Description copied from interface: Filter
Creates an 'inverse' filter

Specified by:
negate in interface Filter<T>
Returns:
a Filter that returns all content except what this Filter instance would.

or

public final Filter<? extends Content> or(Filter<?> filter)
Description copied from interface: Filter
Creates an ORing filter

Specified by:
or in interface Filter<T>
Parameters:
filter - a second Filter to OR with.
Returns:
a new Filter instance that returns the 'union' of this filter and the specified filter.

and

public final Filter<T> and(Filter<?> filter)
Description copied from interface: Filter
Creates an ANDing filter. The generic type of the result is the same as this Filter.

Specified by:
and in interface Filter<T>
Parameters:
filter - a second Filter to AND with.
Returns:
a new Filter instance that returns the 'intersection' of this filter and the specified filter.

refine

public <R> Filter<R> refine(Filter<R> filter)
Description copied from interface: Filter
This is similar to the and(Filter) method except the generic type is different.

Specified by:
refine in interface Filter<T>
Type Parameters:
R - The Generic type of the returned data is taken from the input instance.
Parameters:
filter - The filter to refine our results with.
Returns:
A Filter that requires content to both match our instance and the refining instance, but the generic type of the retuned data is based on the refining instance, not this instance.
