Class PathProperties

java.lang.Object

io.ebean.text.PathProperties

All Implemented Interfaces:

FetchPath

public class PathProperties
extends Object
implements FetchPath

This is a Tree like structure of paths and properties that can be used for defining which parts of an object graph to render in JSON or XML, and can also be used to define which parts to select and fetch for an ORM query.

It provides a way of parsing a string representation of nested path properties and applying that to both what to fetch (ORM query) and what to render (JAX-RS JSON / XML).

Method Detail

parse

public static PathProperties parse(String source)

Parse and return a PathProperties from nested string format like (a,b,c(d,e),f(g)) where "c" is a path containing "d" and "e" and "f" is a path containing "g" and the root path contains "a","b","c" and "f".

toString

public String toString()

Overrides:

toString in class Object

hasPath

public boolean hasPath(String path)

Return true if the path is defined and has properties.

Specified by:

hasPath in interface FetchPath

getProperties

public Set<String> getProperties(String path)

Get the properties for a given path.

Specified by:

getProperties in interface FetchPath

addToPath

public void addToPath(String path,
                      String property)

addNested

public void addNested(String prefix,
                      PathProperties pathProps)

getPathProps

public Collection<PathProperties.Props> getPathProps()

apply

public <T> void apply(Query<T> query)

Apply these path properties as fetch paths to the query.

Specified by:

apply in interface FetchPath

includesProperty

public boolean includesProperty(String name)

Return true if the property (dot notation) is included in the PathProperties.

includesProperty

public boolean includesProperty(String prefix,
                                String name)

Return true if the property is included using a prefix.

includesPath

public boolean includesPath(String path)

Return true if the fetch path is included in the PathProperties.

The fetch path is a OneToMany or ManyToMany path in dot notation.

includesPath

public boolean includesPath(String prefix,
                            String name)

Return true if the path is included using a prefix.
