Method Detail

and

public ConvenientFilter<T> and(Filter<? super T> filter)

Description copied from interface: ConvenientFilter

Combines the two filters using the logical AND operation and returns the combined filter.

Specified by:

and in interface ConvenientFilter<T>

Parameters:

filter - The filter to combine this filter with.

Returns:

The combined filter.

not

public ConvenientFilter<T> not()

Description copied from interface: ConvenientFilter

Creates a filter that negates the result from this filter.

A filter implementing this method is also recommended to implement a method called bitwiseNegate that delegates to this method. That makes it possible to negate the filter using the ~ operator in a Groovy script.

Specified by:

not in interface ConvenientFilter<T>

Returns:

A filter that negates the result from this filter.

bitwiseNegate

public final ConvenientFilter<T> bitwiseNegate()

This method delegates to not()

Since:

1.1.3

The combined filter.

matches

public boolean matches(T object)

Description copied from interface: Filter
