Constructor Details

AlwaysTrueResultSet

public AlwaysTrueResultSet(ModelQueryAdapter adapter,
 RelationalQuery query)

Creates an instance of a AlwaysTrueResultSet record class.

Parameters:

adapter - the value for the adapter record component

query - the value for the query record component

Method Details

getAdapter

public ModelQueryAdapter getAdapter()

Specified by:

getAdapter in interface AnyResultSet

getCanonicalQuery

public Query<Boolean> getCanonicalQuery()

Specified by:

getCanonicalQuery in interface AnyResultSet

Specified by:

getCanonicalQuery in interface ResultSet<Boolean>

size

public int size()

Specified by:

size in interface AnyResultSet

get

public Boolean get(Tuple parameters)

Specified by:

get in interface ResultSet<Boolean>

getAll

public Cursor<Tuple,Boolean> getAll()

Specified by:

getAll in interface ResultSet<Boolean>

addListener

public void addListener(ResultSetListener<Boolean> listener)

Specified by:

addListener in interface ResultSet<Boolean>

removeListener

public void removeListener(ResultSetListener<Boolean> listener)

Specified by:

removeListener in interface ResultSet<Boolean>

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.

adapter

public ModelQueryAdapter adapter()

Returns the value of the adapter record component.

Returns:

the value of the adapter record component

query

public RelationalQuery query()

Returns the value of the query record component.

Returns:

the value of the query record component
