Interface ObjectStrategy<T>

Type Parameters:

T - the keyType of elements maintained by this Collection

All Known Implementing Classes:

ObjectStrategy.IdentityStrategy, ObjectStrategy.NormalStrategy

public interface ObjectStrategy<T>

A Type Specific Strategy class that allows to give control hashcode generation and equals comparason for maps

Modifier and Type	Interface and Description
static class	ObjectStrategy.IdentityStrategy<T> A Strategy that uses Identity HashCode instead of the normal hashing function.
static class	ObjectStrategy.NormalStrategy<T> A Strategy that simulates the normal Hash Collection Behavior if you want to use Hash Control Collections to replace normal ones.

Field Detail

IDENTITY

static final ObjectStrategy<?> IDENTITY

Identity Strategy

NORMAL

static final ObjectStrategy<?> NORMAL

Normal Strategy

Method Detail

identityStrategy

static <T> ObjectStrategy<T> identityStrategy()

Type Parameters:

T - the keyType of elements maintained by this Collection

Returns:

a IdentityStrategy that allows to emulate a IdentityHashMap

normalStrategy

static <T> ObjectStrategy<T> normalStrategy()

Type Parameters:

T - the keyType of elements maintained by this Collection

Returns:

a Normal Strategy that is behaving exactly like the normal Hash Strategy in the Hash Collections

hashCode

int hashCode(T o)

Type Specific HashCode function

Parameters:

o - the element that the hashcode is requested for (if object may be null)

Returns:

hashcode for the given entry

equals

boolean equals(T key,
               T value)

Type Specific Equals function

Parameters:

key - the first element that should be compared with

value - the second element that should be compared with (if object may be null)

Returns:

if the elements match
