Constructor Detail

AndPredicateSemantics.DefaultImplementation

public AndPredicateSemantics.DefaultImplementation(Iterator children)

Constructor

Parameters:

children - iterator over children to add

AndPredicateSemantics.DefaultImplementation

public AndPredicateSemantics.DefaultImplementation(PredicateSemantics child1,
                                                   PredicateSemantics child2)

Constructor

Parameters:

child1 - a child

child2 - a child

AndPredicateSemantics.DefaultImplementation

public AndPredicateSemantics.DefaultImplementation(PredicateSemantics[] children)

Constructor

Parameters:

children - an array of child predicates

Method Detail

getChildren

public List getChildren()

Get the immutable collection of child predicates.

Specified by:

getChildren in interface AndPredicateSemantics

Returns:

Child predicates as an immutable List

perform

public void perform(SongIDResultSet resultSet)
             throws SongDatabaseFailedException

Performs the operation on the given result set.

Specified by:

perform in interface SongOperation

Parameters:

resultSet - the SongIDResultSet

Throws:

SongDatabaseFailedException - Catch-all exception for database-related problems. This will often have a cause exception, which may be exceptions like IOException or SQLException.

equals

public boolean equals(Object obj)

The equals method should return true if the given object is a SongOperation with the same semantics as this one. (i.e. it would perform the same operation.) This may be used to optimize performance. It is always safe to return false from this method, if the semantics of the given object cannot be determined. (This is similar to the equals method in java.util.Comparator.) As a corollary, it is safe just to fall back on the default implementation inherited from java.lang.Object.

Specified by:

equals in interface SongOperation

Parameters:

obj - object to test

Returns:

true if the object is equal
