Field Detail

RDF_trimWhitespace

public static final String RDF_trimWhitespace

Configuration property: Trim whitespace from text elements.

Property:

• Name: "RdfParser.trimWhitespace.b"
• Data type: Boolean
• Default: false
• Session property: false
• Methods:
  • RdfParserBuilder.trimWhitespace(boolean)
  • RdfParserBuilder.trimWhitespace()

Description:

If true, whitespace in text elements will be automatically trimmed.

Example:

// Create an RDF parser that trims whitespace. ReaderParser p = RdfParser .create() .xml() .trimWhitespace() .build(); // Same, but use property. ReaderParser p = RdfParser .create() .xml() .set(RDF_trimWhitespace, true) .build();

Constructor Detail

RdfParser

public RdfParser(PropertyStore ps,
                 String... consumes)

Constructor.

Parameters:

ps - The property store containing all the settings for this object.

consumes - The list of media types that this parser consumes (e.g. "application/json").

RdfParser

public RdfParser(PropertyStore ps)

Constructor.

Parameters:

ps - The property store containing all the settings for this object.

Method Detail

builder

public RdfParserBuilder builder()

Description copied from class: Context

Creates a builder from this context object.

Builders are used to define new contexts (e.g. serializers, parsers) based on existing configurations.

Overrides:

builder in class Parser

Returns:

A new ContextBuilder object.

create

public static RdfParserBuilder create()

Instantiates a new clean-slate RdfParserBuilder object.

This is equivalent to simply calling new RdfParserBuilder().

Note that this method creates a builder initialized to all default settings, whereas builder() copies the settings of the object called on.

Returns:

A new RdfParserBuilder object.

createSession

public RdfParserSession createSession()

Description copied from class: BeanContext

Create a new bean session based on the properties defined on this context.

Use this method for creating sessions if you don't need to override any properties or locale/timezone currently set on this context.

Overrides:

createSession in class Parser

Returns:

A new session object.

createSession

public RdfParserSession createSession(ParserSessionArgs args)

Description copied from class: Parser

Create the session object that will be passed in to the parse method.

It's up to implementers to decide what the session object looks like, although typically it's going to be a subclass of ParserSession.

Specified by:

createSession in class Parser

Parameters:

args - Runtime arguments.

Returns:

The new session.

getCollectionFormat

protected final RdfCollectionFormat getCollectionFormat()

Configuration property: RDF format for representing collections and arrays.

Returns:

RDF format for representing collections and arrays.

See Also:

RdfCommon.RDF_collectionFormat

getJuneauBpNs

protected final Namespace getJuneauBpNs()

Configuration property: Default XML namespace for bean properties.

Returns:

Default XML namespace for bean properties.

See Also:

RdfCommon.RDF_juneauBpNs

getJuneauNs

protected final Namespace getJuneauNs()

Configuration property: XML namespace for Juneau properties.

Returns:

XML namespace for Juneau properties.

See Also:

RdfCommon.RDF_juneauNs

getLanguage

protected final String getLanguage()

Configuration property: RDF language.

Returns:

The RDF language to use.

See Also:

RdfCommon.RDF_language

isLooseCollections

protected final boolean isLooseCollections()

Configuration property: Collections should be serialized and parsed as loose collections.

Returns:

true if collections of resources are handled as loose collections of resources in RDF instead of resources that are children of an RDF collection (e.g. Sequence, Bag).

See Also:

RdfCommon.RDF_looseCollections

getJenaProperties

protected final Map<String,Object> getJenaProperties()

Configuration property: All Jena-related configuration properties.

Returns:

A map of all Jena-related configuration properties.

isTrimWhitespace

protected final boolean isTrimWhitespace()

Configuration property: Trim whitespace from text elements.

Returns:

true if whitespace in text elements will be automatically trimmed.

See Also:

RDF_trimWhitespace

toMap

public ObjectMap toMap()

Description copied from class: Context

Returns the properties defined on this bean context as a simple map for debugging purposes.

Overrides:

toMap in class ReaderParser

Returns:

A new map containing the properties defined on this context.
