All Implemented Interfaces:

Serializable, Resource, AliasedObject

public class CollectionResourceWrapper
extends Object
implements Resource

A wrapper around a Resouce that allows for a marshalled collection to be read from it. Call to getProperty(String) will return the first (or next) property that is registered under that name. Calling getProperty(String) again will return the next one.

                     throws SearchEngineException

Description copied from interface: Resource

Adds a property to the resource based on resource mapping definitions. If the property already exists in the resource (the name exists), it will be added on top of it (won't replace it). ONLY use this method with resource mapping.

Specified by:

addProperty in interface Resource

Parameters:

name - the name of the property

value - the value to be set (will be converted to a string).

Throws:

SearchEngineException

addProperty

public Resource addProperty(String name,
                            Reader value)
                     throws SearchEngineException

Description copied from interface: Resource

Adds a property to the resource based on resource mapping definitions. If the property already exists in the resource (the name exists), it will be added on top of it (won't replace it). ONLY use this method with resource mapping.

Specified by:

addProperty in interface Resource

Parameters:

name - the name of the property

value - the value to be set (will be converted to a string).

Throws:

SearchEngineException

addProperty

public Resource addProperty(Property property)

Description copied from interface: Resource

Add a property to the resource. If the property already exists in the resource (the name exists), it will be added on top of it (won't replace it). Note: Compass adds all properties specified in mapping file, adding extra properties to a Resource will make the index out of sync with mapping.

Specified by:

addProperty in interface Resource

Parameters:

property - The properyt to add

removeProperty

public Resource removeProperty(String name)

Description copied from interface: Resource

Remove the latest property added under the given name.

Specified by:

                     throws SearchEngineException

Description copied from interface: Resource

Sets a property to the resource (removes then adds) based on resource mapping definitions. If the property already exists in the resource (the name exists), it will be added on top of it (won't replace it). ONLY use this method with resource mapping.

Specified by:

setProperty in interface Resource

Parameters:

setProperty

public Resource setProperty(Property property)

Description copied from interface: Resource

Sest a property to the resource (removes then adds). If the property already exists in the resource (the name exists), it will be added on top of it (won't replace it).

Specified by:

setProperty in interface Resource

Parameters:

property - The properyt to add

getProperty

public Property getProperty(String name)

Description copied from interface: Resource

Returns the first property under the name.

Specified by:

getProperty in interface Resource

Parameters:

name - The name of the property

Returns:

The first proeprty that match the name

public Property[] getProperties(String name)

Description copied from interface: Resource

Returns all the properties under the given name.

name - The name of the properties

Returns:

An array of properties that match the name

Description copied from interface: Resource

Returns an array of values of the proeprty with the given name. This method returns an empty array if no values are associated with the given name.

If a converter is associated with the property in one of Compass mapping definitions, it will be used to convert the string value to an object value. If there is no converter associated with the property, the string value will be returned.

Specified by:

getObjects in interface Resource

getProperties

public Property[] getProperties()

Description copied from interface: Resource

Returns all the properties for the resource.

Specified by:

getProperties in interface Resource

Returns:

All the properties

getBoost

public float getBoost()

Description copied from interface: Resource

Returns, at indexing time, the boost factor as set by Resource.setBoost(float).

Note that once a document is indexed this value is no longer available from the index. At search time, for retrieved documents, this method always returns 1. This however does not mean that the boost value set at indexing time was ignored - it was just combined with other indexing time factors and stored elsewhere, for better indexing and search performance. (For more information see the "norm(t,d)" part of the scoring formula in Similarity.)

Specified by:

getBoost in interface Resource

Returns:

The boost value

setBoost

public Resource setBoost(float boost)

Description copied from interface: Resource

/** Sets a boost factor for hits on any field of this document. This value will be multiplied into the score of all hits on this document.

The default value is 1.0.

Values are multiplied into the value of Property.getBoost() of each properties of the resource. Thus, this method in effect sets a default boost for the fields of this document.

Specified by:

setBoost in interface Resource

Parameters:

boost - The boost level for the resource

Property.setBoost(float)

copy

public void copy(Resource resource)

Description copied from interface: Resource

Copies the content of the give Resource into the current one

Specified by:

copy in interface Resource

Parameters:

resource - The resource to copy from
