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-overridable: true
• 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 ReaderParserSession 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.

asMap

public ObjectMap asMap()

Description copied from class: Context

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

Overrides:

asMap in class Parser

Returns:

A new map containing the properties defined on this context.
