public SqlFunctionRegistry(SqlFunctionRegistry.Select select,
 SqlFunctionRegistry.Aggregate aggregate,
 SqlFunctionRegistry.Scalar scalar,
 SqlFunctionRegistry.Date date)

Creates an instance of a SqlFunctionRegistry record class.

Parameters:

select - the value for the select record component

aggregate - the value for the aggregate record component

scalar - the value for the scalar record component

date - the value for the date 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.
