Field Detail

OneToOne

public static final AssociationType OneToOne

Specifies a single-valued association to another entity that has one-to-one multiplicity. It is not normally necessary to specify the associated target entity explicitly since it can usually be inferred from the type of the object being referenced.

OneToMany

public static final AssociationType OneToMany

Specifies a muliti-valued association to another entity that has one-to-many multiplicity.

ManyToOne

public static final AssociationType ManyToOne

Specifies a single-valued association to another entity that has many-to-one multiplicity. It is not normally necessary to specify the associated target entity explicitly since it can usually be inferred from the type of the object being referenced.

ManyToMany

public static final AssociationType ManyToMany

Specifies a many-valued association with many-to-many multiplicity. If the Collection is defined using generics to specify the element type, the associated target entity class does not need to be specified; otherwise it must be specified.

Every many-to-many association has two sides, the owning side and the non-owning, or inverse, side. If the association is bidirectional, either side may be designated as the owning side

Method Detail

toString

public String toString()

Returns a string representation of the AssociationType.

Overrides:

toString in class Object

Returns:

a string representation of the AssociationType.

getAssociationType

public int getAssociationType()

Retreive the value of this AssociationType. Can be useful when using with a switch statement.

Returns:

the int value of this AssociationType.

hashCode

public int hashCode()

Retrieves the hash code of this AssociationType object.

Overrides:

hashCode in class Object

Returns:

the hash code value of this object.

equals

public boolean equals(Object obj)

Returns true if the input object is equivalent to this AssociationType.

Overrides:

equals in class Object

Parameters:

obj - the object with which to compare.

Returns:

true if the input Object is equivalent to this AssociationType
