All Implemented Interfaces:

Condition<T>, Partial<T>

Enclosing class:

QBuilder<T extends QBuilder<T>>

protected final class QBuilder.ConditionDelegate
extends Delegate<T>
implements Condition<T>

A delegate view of this builder that represents a logically complete condition. A logically complete condition can either be directly built into a query or it can be composed with other conditions in the form of 'AND' or 'OR'

Method Summary

Modifier and Type	Method and Description
T	and() Prepare to append another condition onto the current node in the condition tree in such a way that both the preceeding condition AND the next condition specified must be met in order to match an object.
LogicalNode	getRootNode()
T	or() Prepare to append another condition onto the current node in the condition tree in such a way that both the preceeding condition OR the next condition specified must be met in order to match an object.
<Q,S> Q	query(ContextualNodeVisitor<Q,S> visitor, S context) Given this logically complete condition, execute a node visitor against the underlying condition tree in order to build a query or predicate against which objects can be queried / tested.
<Q> Q	query(ContextualNodeVisitor<Q,Void> visitor) Given this logically complete condition, execute a node visitor against the underlying condition tree in order to build a query or predicate against which objects can be queried / tested.

Method Detail

and

public final T and()

Description copied from interface: Condition

Prepare to append another condition onto the current node in the condition tree in such a way that both the preceeding condition AND the next condition specified must be met in order to match an object. If more flexibility surrounding precedence is needed than what chaining provides, please see Partial.and(List) and Partial.or(List).

Specified by:

and in interface Condition<T extends QBuilder<T>>

Returns:

The beginnings of another condition.

or

public final T or()

Description copied from interface: Condition

Prepare to append another condition onto the current node in the condition tree in such a way that both the preceeding condition OR the next condition specified must be met in order to match an object. If more flexibility surrounding precedence is needed than what chaining provides, please see Partial.and(List) and Partial.or(List).

Specified by:

or in interface Condition<T extends QBuilder<T>>

Returns:

The beginnings of another condition.

query

public final <Q> Q query(ContextualNodeVisitor<Q,Void> visitor)

Description copied from interface: Condition

Given this logically complete condition, execute a node visitor against the underlying condition tree in order to build a query or predicate against which objects can be queried / tested.

Specified by:

query in interface Condition<T extends QBuilder<T>>

Type Parameters:

Q - The type of the results returned from visiting any node in the tree.

Parameters:

visitor - The visitor which specifies how to traverse the nodes in the visitor tree. Nodes can be AndNodes or OrNodes or ComparisonNodes.

Returns:

The result of the visitor's execution.

query

public final <Q,S> Q query(ContextualNodeVisitor<Q,S> visitor,
                           S context)

Description copied from interface: Condition

Given this logically complete condition, execute a node visitor against the underlying condition tree in order to build a query or predicate against which objects can be queried / tested.

Specified by:

query in interface Condition<T extends QBuilder<T>>

Type Parameters:

Q - The type of the results returned from visiting any node in the tree.

Parameters:

visitor - The visitor which specifies how to traverse the nodes in the visitor tree. Nodes can be AndNodes or OrNodes or ComparisonNodes.

Returns:

The result of the visitor's execution.
