Class AbstractPropertyQuery<T>

java.lang.Object

repast.simphony.query.AbstractPropertyQuery<T>

All Implemented Interfaces:

Query<T>

Direct Known Subclasses:

PropertyEquals, PropertyGreaterThan, PropertyGreaterThanEquals, PropertyLessThan, PropertyLessThanEquals, PropertyNotEquals

public abstract class AbstractPropertyQuery<T>
extends Object
implements Query<T>

Deprecated.

Use Context.getObjectsAsStream(Class) and the Java 8+ streaming API Stream instead.

Abstact implementation of a query that queries based on an object's property. A property is defined in the standard java bean way as a getter or setter, such that the presence of a getFoo or setFoo method defines a "foo" property.

Constructor Detail

AbstractPropertyQuery

public AbstractPropertyQuery(Context<T> context,
                             String propertyName,
                             Object propertyValue)

Deprecated.

Creates an AbstractProperty query to query the specified contexts using the specified property name and value.

Parameters:

context -

propertyName -

propertyValue -

Method Detail

getQueryPredicate

public org.apache.commons.collections15.Predicate<T> getQueryPredicate()

Deprecated.

Gets the Predicate that will be used in this Predicate's next call to query().

Returns:

the Predicate that will be used in this Predicate's next call to query().

createPredicate

protected abstract org.apache.commons.collections15.Predicate<T> createPredicate(Context<T> context,
                                                                                 String propertyName)

Deprecated.

Implemented by subclasses to return the appropriate Predicate. For example, a property equals query predicate will return true if an object has that property and its value is equal to the value specified in the constructor.

Parameters:

context -

propertyName -

Returns:

the Predicate appropriate to the implementing sub class.

query

public Iterable<T> query()

Deprecated.

Returns the result of the query.

Specified by:

query in interface Query<T>

Returns:

an iterable over the objects that are the result of the query.

propertyNotFound

protected void propertyNotFound(String propertyName)

Deprecated.

query

public Iterable<T> query(Iterable<T> iter)

Deprecated.

Returns an iterable over the objects that are the result of the query and are in the passed in iterable. This allows queries to be chained together where the result of one query is passed into another.

Specified by:

query in interface Query<T>

Parameters:

iter -

Returns:

an iterable over the objects that are the result of the query and are in the passed in iterable.
