Constructor Details

JsonParserSession

protected JsonParserSession(JsonParserSession.Builder builder)

Constructor.

Parameters:

builder - The builder for this object.

Method Details

create

public static JsonParserSession.Builder create(JsonParser ctx)

Creates a new builder for this object.

Parameters:

ctx - The context creating this session.

Returns:

A new builder.

isWhitespace

protected boolean isWhitespace(int cp)

Returns true if the specified character is whitespace.

The definition of whitespace is different for strict vs lax mode. Strict mode only interprets 0x20 (space), 0x09 (tab), 0x0A (line feed) and 0x0D (carriage return) as whitespace. Lax mode uses Character.isWhitespace(int) to make the determination.

Parameters:

cp - The codepoint.

Returns:

true if the specified character is whitespace.

isCommentOrWhitespace

protected boolean isCommentOrWhitespace(int cp)

Returns true if the specified character is whitespace or '/'.

Parameters:

cp - The codepoint.

Returns:

true if the specified character is whitespace or '/'.

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 IOException,
ParseException,
ExecutableException

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:

IOException

ParseException

ExecutableException

doParseIntoCollection

protected <E> Collection<E> doParseIntoCollection(ParserPipe pipe,
 Collection<E> c,
 Type elementType)
                                           throws IOException,
ParseException,
ExecutableException

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:

IOException

ParseException

ExecutableException

isValidateEnd

protected boolean isValidateEnd()

Validate end.

Returns:

true if after parsing a POJO from the input, verifies that the remaining input in the stream consists of only comments or whitespace.

See Also:

• JsonParser.Builder.validateEnd()

getJsonClassMeta

protected JsonClassMeta getJsonClassMeta(ClassMeta<?> cm)

Returns the language-specific metadata on the specified class.

Parameters:

cm - The class to return the metadata on.

Returns:

The metadata.
