Constructor Detail

CollectionQuery

public CollectionQuery(java.util.Collection<T> collection)

Method Detail

findAll

public java.util.Collection<T> findAll()

Description copied from interface: Query

Get all of the results in the Collection

Specified by:

findAll in interface Query<T>

Returns:

results in a collection or empty collection if no results found.

findFirst

public T findFirst()

Description copied from interface: Query

Get the first result or null if no results have been found.

Specified by:

findFirst in interface Query<T>

Returns:

first result of the search or null if no results.

forEach

public boolean forEach(Processor<? super T> consumer)

Description copied from interface: Query

Process search results one-by-one. All the results will be subsequently fed to a consumer passed. The consumer might be called on different threads, but by default these calls are mutually exclusive, so no additional synchronization inside consumer is necessary. If you need to process results in parallel, run forEach() on the result of Query.allowParallelProcessing().

Specified by:

forEach in interface Query<T>

Parameters:

consumer - - a processor search results should be fed to.

Returns:

true if the search was completed normally, false if the occurrence processing was cancelled by the processor.

forEachAsync

public AsyncFuture<java.lang.Boolean> forEachAsync(Processor<? super T> consumer)

Specified by:

forEachAsync in interface Query<T>

toArray

public T [] toArray(T [] a)

Specified by:

toArray in interface Query<T>

iterator

public java.util.Iterator<T> iterator()

Specified by:

iterator in interface java.lang.Iterable<T>
