Constructor Detail

ElementParser

protected ElementParser(AltFormat altFormat,
             java.lang.Class<T> resultType)

Constructs a new ElementParser instance for parsing content in a a particular representation to produce results of a specified type.

Parameters:

altFormat - parsed alternate representation

resultType - expected result type

Throws:

java.lang.IllegalArgumentException - if the representation does not have an associated wire format that can be used to parse the content.

Method Detail

of

public static <T> ElementParser<T> of(AltFormat altFormat,
                      java.lang.Class<T> resultType)

Provides a factory method to create a new ElementParser that handles a particular representation to produce a particular type of result.

Type Parameters:

T - base type of parse result objects

Parameters:

altFormat - alternate representation parsed

resultType - type of result object produced

Returns:

an element parser with the desired configuration

Throws:

java.lang.IllegalArgumentException - if the representation does not have an associated wire format that can be used to parse the content.

parse

public <R extends T> R parse(java.io.Reader inputReader,
                    InputProperties inProps,
                    java.lang.Class<R> resultClass)
                  throws java.io.IOException,
                         ServiceException

Description copied from class: CharacterParser

Parses character content with the specified properties to produce a result of an expected type. Concrete subclasses will provide an implementation of this method that constructs a result type instance of the result class and then parses into it from the provided Reader.

Specified by:

parse in class CharacterParser<T>

Type Parameters:

R - expected result type

Parameters:

inputReader - reader to parse data from

inProps - input properties

resultClass - class to instantiate and parse result into.

Returns:

result object from parse

Throws:

java.io.IOException - if an error occurred reading data while parsing

ServiceException - if an error occurred within the content
