Constructor Details

UonParserSession

protected UonParserSession(UonParserSession.Builder builder)

Constructor.

Parameters:

builder - The builder for this object.

Method Details

create

public static UonParserSession.Builder create(UonParser ctx)

Creates a new builder for this object.

Parameters:

ctx - The context creating this session.

Returns:

A new builder.

doParse

protected <T> T doParse(ParserPipe pipe,
 ClassMeta<T> type)
                 throws IOException,
ParseException,
ExecutableException

Description copied from class: ParserSession

Workhorse method.

Subclasses are expected to implement this method or Parser.doParse(ParserSession,ParserPipe,ClassMeta).

The default implementation of this method simply calls Parser.doParse(ParserSession,ParserPipe,ClassMeta).

Overrides:

doParse in class ParserSession

Type Parameters:

T - The class type of the object to create.

Parameters:

pipe - Where to get the input from.

type - The class type of the object to create. If null or Object.class, object type is based on what's being parsed. For example, when parsing JSON text, it may return a String, Number, JsonMap, etc...

Returns:

The parsed object.

Throws:

IOException - Thrown by underlying stream.

ParseException - Malformed input encountered.

ExecutableException - Exception occurred on invoked constructor/method/field.

doParseIntoMap

protected <K,
V> Map<K,V> doParseIntoMap(ParserPipe pipe,
 Map<K,V> m,
 Type keyType,
 Type valueType)
                                 throws Exception

Description copied from class: ParserSession

Implementation method.

Default implementation throws an UnsupportedOperationException.

Overrides:

doParseIntoMap in class ParserSession

Type Parameters:

K - The key type.

V - The value type.

Parameters:

pipe - The parser input.

m - The map being loaded.

keyType - The class type of the keys, or null to default to String.class.

valueType - The class type of the values, or null to default to whatever is being parsed.

Returns:

The same map that was passed in to allow this method to be chained.

Throws:

Exception - If thrown from underlying stream, or if the input contains a syntax error or is malformed.

doParseIntoCollection

protected <E> Collection<E> doParseIntoCollection(ParserPipe pipe,
 Collection<E> c,
 Type elementType)
                                           throws Exception

Description copied from class: ParserSession

Implementation method.

Default implementation throws an UnsupportedOperationException.

Overrides:

doParseIntoCollection in class ParserSession

Type Parameters:

E - The element type.

Parameters:

pipe - The parser input.

c - The collection being loaded.

elementType - The class type of the elements, or null to default to whatever is being parsed.

Returns:

The same collection that was passed in to allow this method to be chained.

Throws:

Exception - If thrown from underlying stream, or if the input contains a syntax error or is malformed.

parse

public <T> T parse(HttpPartType partType,
 HttpPartSchema schema,
 String in,
 ClassMeta<T> toType)
            throws ParseException,
SchemaValidationException

Description copied from interface: HttpPartParserSession

Converts the specified input to the specified class type.

Specified by:

parse in interface HttpPartParserSession

Type Parameters:

T - The POJO type to transform the input into.

Parameters:

partType - The part type being parsed.

schema - Schema information about the part.
May be null.
Not all part parsers use the schema information.

in - The input being parsed.

toType - The POJO type to transform the input into.

Returns:

The parsed value.

Throws:

ParseException - Malformed input encountered.

SchemaValidationException - If the input or resulting HTTP part object fails schema validation.

parseAnything

public <T> T parseAnything(ClassMeta<?> eType,
 UonReader r,
 Object outer,
 boolean isUrlParamValue,
 BeanPropertyMeta pMeta)
                    throws IOException,
ParseException,
ExecutableException

Workhorse method.

Type Parameters:

T - The class type being parsed, or null if unknown.

Parameters:

eType - The class type being parsed, or null if unknown.

r - The reader being parsed.

outer - The outer object (for constructing nested inner classes).

isUrlParamValue - If true, then we're parsing a top-level URL-encoded value which is treated a bit different than the default case.

pMeta - The current bean property being parsed.

Returns:

The parsed object.

Throws:

IOException - Thrown by underlying stream.

ParseException - Malformed input encountered.

ExecutableException - Exception occurred on invoked constructor/method/field.

parseAttr

                              throws IOException,
ParseException

Parses an attribute name from the specified reader.

Parameters:

r - The reader.

encoded - Whether the attribute is encoded.

Returns:

The parsed attribute name.

Throws:

IOException - Exception thrown by underlying stream.

ParseException - Malformed input found.

getUonReader

public final UonReader getUonReader(ParserPipe pipe,

decodeChars - Whether the reader should automatically decode URL-encoded characters.

Returns:

A new UonReader object.

Throws:

IOException - Thrown by underlying stream.

isDecoding

protected final boolean isDecoding()

Decode "%xx" sequences.
