renderCondition

public String renderCondition(String columnName,
                              String placeholder)

Specified by:

renderCondition in class AbstractSingleValueCondition<T>

of

public static <T> IsEqualTo<T> of(T value)

when

@Deprecated
public IsEqualTo<T> when(Predicate<T> predicate)

Deprecated. replaced by filter(Predicate)

If renderable and the value matches the predicate, returns this condition. Else returns a condition that will not render.

Parameters:

predicate - predicate applied to the value, if renderable

Returns:

this condition if renderable and the value matches the predicate, otherwise a condition that will not render.

then

@Deprecated
public IsEqualTo<T> then(UnaryOperator<T> mapper)

Deprecated. replaced by map(Function)

If renderable, apply the mapping to the value and return a new condition with the new value. Else return a condition that will not render (this).

Parameters:

mapper - a mapping function to apply to the value, if renderable

Returns:

a new condition with the result of applying the mapper to the value of this condition, if renderable, otherwise a condition that will not render.

filter

public IsEqualTo<T> filter(Predicate<? super T> predicate)

Description copied from class: AbstractSingleValueCondition

If renderable and the value matches the predicate, returns this condition. Else returns a condition that will not render.

Specified by:

filter in class AbstractSingleValueCondition<T>

Parameters:

predicate - predicate applied to the value, if renderable

Returns:

this condition if renderable and the value matches the predicate, otherwise a condition that will not render.

map

public <R> IsEqualTo<R> map(Function<? super T,? extends R> mapper)

If renderable, apply the mapping to the value and return a new condition with the new value. Else return a condition that will not render (this).

Type Parameters:

R - type of the new condition

Parameters:

mapper - a mapping function to apply to the value, if renderable

Returns:

a new condition with the result of applying the mapper to the value of this condition, if renderable, otherwise a condition that will not render.
