org.joda.beans.query
Class ChainedBeanQuery<P>

java.lang.Object
  extended by org.joda.beans.query.ChainedBeanQuery<P>
Type Parameters:
P - the type of the result of the query
All Implemented Interfaces:
BeanQuery<P>
Deprecated. Use functional interfaces in Java SE 8 

@Deprecated
public final class ChainedBeanQuery<P>
extends Object
implements BeanQuery<P>

A chained query, that allows two or more queries to be joined.

For example, consider a structure where class A has a property b of type B, and class B has a property c of type C. The compound query allows property c to be accessed directly from an instance of A.

Method Detail

of

public static <P> ChainedBeanQuery<P> of(BeanQuery<? extends Bean> prop1,
                                         BeanQuery<P> prop2)
Deprecated. 
Obtains a chained query from two other queries.

MetaProperty implements BeanQuery, so typically the parameters are in fact meta-properties.

Type Parameters:
P - the result type
Parameters:
prop1 - the first query, not null
prop2 - the second query, not null
Returns:
the compound query, not null
Throws:
IllegalArgumentException - if unable to obtain the meta-bean

of

public static <P> ChainedBeanQuery<P> of(BeanQuery<? extends Bean> prop1,
                                         BeanQuery<? extends Bean> prop2,

Deprecated. 
Obtains a chained query from three queries.

MetaProperty implements BeanQuery, so typically the parameters are in fact meta-properties.

Type Parameters:
P - the result type
Parameters:
prop1 - the first query, not null
prop2 - the second query, not null
prop3 - the third query, not null
Returns:
the compound query, not null
Throws:
IllegalArgumentException - if unable to obtain the meta-bean

of

public static <P> ChainedBeanQuery<P> of(BeanQuery<? extends Bean> prop1,
                                         BeanQuery<? extends Bean> prop2,
                                         BeanQuery<? extends Bean> prop3,
                                         BeanQuery<P> prop4)

MetaProperty implements BeanQuery, so typically the chain is formed from meta-properties.

Returns:
the list of all meta-properties being chained, not null
