Package org.hibernate.search.mapper.pojo.model.path

Class PojoModelPath

java.lang.Object

org.hibernate.search.mapper.pojo.model.path.PojoModelPath

Direct Known Subclasses:

PojoModelPathPropertyNode, PojoModelPathValueNode

public abstract class PojoModelPath
extends Object

Represents an arbitrarily long access path when walking the POJO model.

For instance the path could be: property "propertyOfA" => extractor "MapValueExtractor" => property "propertyOfB" Meaning: extract property "propertyOfA", then extract values using "MapValueExtractor", then for each value extract property "propertyOfB".

Method Detail

builder

public static PojoModelPath.Builder builder()

Returns:

A builder allowing to create a PojoModelPath by specifying its components (property, container extractors) one by one.

ofProperty

public static PojoModelPathPropertyNode ofProperty(String propertyName)

Parameters:

propertyName - The name of a POJO property.

Returns:

A path from a POJO to the property with the given name.

ofValue

public static PojoModelPathValueNode ofValue(String propertyName)

Parameters:

propertyName - The name of a POJO property.

Returns:

A PojoModelPath from a POJO to the value(s) of the property with the given name. Default container extractors are applied to the property, so that for example a path to a List property will in fact point to the elements of that list.

ofValue

public static PojoModelPathValueNode ofValue(String propertyName,
                                             ContainerExtractorPath extractorPath)

Parameters:

propertyName - The name of a POJO property.

extractorPath - A container extractor path.

Returns:

A PojoModelPath from a POJO to the value(s) of the property with the given name. The extractors represented by the given extractor path are applied to the property, so that for example a path to a List property may in fact point to the elements of that list.

parse

public static PojoModelPathValueNode parse(String dotSeparatedPath)

Parameters:

dotSeparatedPath - A dot-separated path, such as "myProperty.someNestedProperty".

Returns:

A PojoModelPath representing the same path, which the default container extractors applied to each property, so that for example a path to a List property will in fact point to the elements of that list.

toString

public String toString()

Overrides:

toString in class Object

toPathString

public final String toPathString()

Returns:

A representation of this path in the form propertyA<containerExtractorPathA>.propertyB<containerExtractorPathB>.propertyC<containerExtractorPathB>.

parent

public abstract PojoModelPath parent()

Returns:

The model path to the element from which the value represented by this node is extracted. May be null.
