Field Detail

COMPARABLE_COMPARATOR

static final Comparator<Comparable<Object>> COMPARABLE_COMPARATOR

A Comparator for comparing Comparable instances.

TO_STRING_COMPARATOR

static final Comparator<?> TO_STRING_COMPARATOR

A Comparator for comparing Objects according to their toString() value.

Method Detail

columnClass

Class<?> columnClass(C columnIdentifier)

Returns the class of the column with the given identifier

Parameters:

columnIdentifier - the column identifier

Returns:

the Class representing the given column

comparator

default Comparator<?> comparator(C columnIdentifier)

Returns the comparator to use when sorting by the give column, the comparator receives the column values, but never null.

Parameters:

columnIdentifier - the column identifier

Returns:

the comparator to use when sorting by the given column

value

Object value(R row,
             C columnIdentifier)

Returns a value for the given row and columnIdentifier

Parameters:

row - the object representing a given row

columnIdentifier - the column identifier

Returns:

a value for the given row and column

string

default String string(R row,
                      C columnIdentifier)

Returns a String representation of the value for the given row and columnIdentifier

Parameters:

row - the row

columnIdentifier - the column identifier

Returns:

a String representation of the value for the given row and column

comparable

default <T> Comparable<T> comparable(R row,
                                     C columnIdentifier)

Returns a Comparable instance for the given row and columnIdentifier. The default implementation simply assumes the value is a Comparable instance and performs a cast.

Type Parameters:

T - the column value type

Parameters:

row - the object representing a given row

columnIdentifier - the column identifier

Returns:

a Comparable for the given row and column
