Constructor Details

ForeignKey

public ForeignKey(@Nullable String constraint,
 @Nullable String table,
 @Nullable Class<? extends Data> type,
 List<Metamodel<?,?>> fields)

Creates an instance of a ForeignKey record class.

Parameters:

constraint - the value for the constraint record component

table - the value for the table record component

type - the value for the type record component

fields - the value for the fields record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

constraint

public @Nullable String constraint()

Returns the value of the constraint record component.

Specified by:

constraint in interface IntegrityViolation

Returns:

the value of the constraint record component

table

public @Nullable String table()

Returns the value of the table record component.

Specified by:

table in interface IntegrityViolation

Returns:

the value of the table record component

type

public @Nullable Class<? extends Data> type()

Returns the value of the type record component.

Specified by:

type in interface IntegrityViolation

Returns:

the value of the type record component

fields

public List<Metamodel<?,?>> fields()

Returns the value of the fields record component.

Specified by:

fields in interface IntegrityViolation

Returns:

the value of the fields record component
