Constructor Detail

DataInputNavigableJsonAdapter

public DataInputNavigableJsonAdapter(BufferObjectDataInput input,
                                     int initialOffset)

Method Detail

position

public void position(int position)

Description copied from class: NavigableJsonInputAdapter

Sets the position of underlying data input.

Specified by:

position in class NavigableJsonInputAdapter

position

public int position()

Description copied from class: NavigableJsonInputAdapter

Gives the current position of the cursor.

Specified by:

position in class NavigableJsonInputAdapter

Returns:

the current read position of the cursor

reset

public void reset()

Description copied from class: NavigableJsonInputAdapter

Resets the read cursor.

Specified by:

reset in class NavigableJsonInputAdapter

isAttributeName

public boolean isAttributeName(JsonPathCursor cursor)

Description copied from class: NavigableJsonInputAdapter

This method verifies that the underlying input currently points to an attribute name of a Json object. JsonPathCursor.getCurrent() method is called to retrieve the attribute name. The cursor is moved to the end of the attribute name, after quote character if successful. Otherwise cursor might be in any position further forward than where it was prior to this method.

Specified by:

isAttributeName in class NavigableJsonInputAdapter

Returns:

true if the given attributeName matches the one in underlying data input

parseValue

public JsonValue parseValue(JsonReducedValueParser parser,
                            int offset)
                     throws IOException

Description copied from class: NavigableJsonInputAdapter

Tries to parse a single JsonValue from the input. The offset must be pointing to the beginning of a scalar Json value.

Specified by:

parseValue in class NavigableJsonInputAdapter

Returns:

either null or a scalar JsonValue.

Throws:

IOException - if offset is pointing to a non-scalar or invalid Json input

createParser

public com.fasterxml.jackson.core.JsonParser createParser(com.fasterxml.jackson.core.JsonFactory factory)
                                                   throws IOException

Description copied from class: NavigableJsonInputAdapter

Creates a parser from given factory

Specified by:

createParser in class NavigableJsonInputAdapter

Returns:

the parser

Throws:

IOException
