Method Detail

registerComparator

public void registerComparator(String fieldLocation,
                               Comparator<?> comparator)

Puts the comparator for the given fieldLocation.

Parameters:

fieldLocation - the FieldLocation where to apply the comparator

comparator - the comparator itself

hasComparatorForField

public boolean hasComparatorForField(String fieldLocation)

Checks, whether an any comparator is associated with the giving field location.

Parameters:

fieldLocation - the field location which association need to check

Returns:

is field location contain a custom comparator

getComparatorForField

public Comparator<?> getComparatorForField(String fieldLocation)

Retrieves a custom comparator, which is associated with the giving field location. If this location does not associate with any custom comparators - this method returns null.

Parameters:

fieldLocation - the field location that has to be associated with a comparator

Returns:

a custom comparator or null

comparatorByFields

public Stream<Map.Entry<String,Comparator<?>>> comparatorByFields()

Returns a sequence of associated field-comparator pairs.

Returns:

sequence of field-comparator pairs

put

public void put(String fieldLocation,
                T entity)

Pairs the giving entity with the fieldLocation.

Parameters:

fieldLocation - the field location where to apply the giving entity

entity - the entity to pair

get

public T get(String fieldLocation)

Retrieves a specific entity which is associated with the giving filedLocation from the field holder, if it presents. Otherwise, this method returns null.

Parameters:

fieldLocation - the field location which has to be associated with an entity

Returns:

entity or null

hasEntity

public boolean hasEntity(String fieldLocation)

Checks, whether an any entity associated with the giving field location.

Parameters:

fieldLocation - the field location which association need to check

Returns:

is entity associated with field location

isEmpty

public boolean isEmpty()

Returns:

true is there are registered entities, false otherwise

entryByField

public Stream<Map.Entry<String,T>> entryByField()

Returns a sequence of all field-entry pairs which the current holder supplies.

Returns:

sequence of field-entry pairs

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
