public NavigableJsonInputAdapter()

Method Detail

position

public abstract void position(int position)

Sets the position of underlying data input.

Parameters:

position -

position

public abstract int position()

Gives the current position of the cursor.

Returns:

the current read position of the cursor

reset

public abstract void reset()

Resets the read cursor.

isAttributeName

public abstract boolean isAttributeName(JsonPathCursor cursor)

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.

Parameters:

cursor -

Returns:

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

parseValue

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

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

Parameters:

parser -

offset -

Returns:

either null or a scalar JsonValue.

Throws:

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

createParser

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

Creates a parser from given factory

Parameters:

factory -

Returns:

the parser

Throws:

IOException
