Constructor Detail

RbfLowLevelDeserializerImpl

public RbfLowLevelDeserializerImpl(C config)

Constructs a new RbfLowLevelDeserializerImpl.

Parameters:

config - the configuration object

Method Detail

open

public final void open(Reader reader)

Opens a new deserialization stream based on the given reader.

Specified by:

open in interface LowLevelDeserializer

Parameters:

reader - the reader to base the stream on.

readNextRecord

public final boolean readNextRecord()

Reads the next record from the stream. Returns true, if it could be read and false otherwise.

Specified by:

readNextRecord in interface RbfLowLevelDeserializer

Returns:

true, if another record could be read from the stream, otherwise false.

unreadRecord

public final void unreadRecord()

Unreads the already read record so that it can be read again with RbfLowLevelDeserializer.readNextRecord().

Specified by:

unreadRecord in interface RbfLowLevelDeserializer

close

public final void close(boolean closeReader)

Closes the deserialization stream. The underlying reader will be closed only if closeReader is true.

Specified by:

close in interface LowLevelDeserializer

Parameters:

closeReader - if true, the underlying reader will be closed, too.

getInputPosition

public final InputPosition getInputPosition()

Returns information about the current position within the input stream.

Specified by:

getInputPosition in interface LowLevelDeserializer

Returns:

the input position or null if no position information is available

getStoredLines

public List<Line> getStoredLines()

Returns a list of lines stored during deserialization.

Specified by:

getStoredLines in interface RbfLowLevelDeserializer

Returns:

a list of lines

LineFilter

getConfiguration

protected final C getConfiguration()

Returns the configuration object.

Returns:

the configuration object

hasNextChar

protected final boolean hasNextChar()

Returns true, if there is another character on the current line segment to read.

Returns:

true, if there is another character on the current line segment to read; false otherwise.

peekChar

protected final char peekChar()

Returns the current character of the current line segment.

Returns:

a character

nextChar

protected final char nextChar()

Returns the next character of the current line segment and moves one character forward.

Returns:

a character

nextString

protected final String nextString(int length)

Returns the next String with the given length of the current line segment and moves forward accordingly.

Parameters:

length - the length of the String to return

Returns:

a String

remainingLineLength

protected final int remainingLineLength()

Returns:

the number of remaining characters in the current line segment.

readNextSegment

protected boolean readNextSegment()

Reads the next segment from the stream.

Returns:

true, if a segment could be read; false otherwise

getCurrentSegmentTerminatorString

protected String getCurrentSegmentTerminatorString()

Returns:

the string terminating the current segment.

getCurrentSegmentTerminator

protected LineSegment.Terminator getCurrentSegmentTerminator()

Returns:

the terminator of the current segment.
