Constructor Detail

DefaultCharInputReader

public DefaultCharInputReader(char normalizedLineSeparator,
                              int bufferSize,
                              int whitespaceRangeStart,
                              boolean closeOnStop)

Creates a new instance with the mandatory characters for handling newlines transparently. Line separators will be detected automatically.

Parameters:

normalizedLineSeparator - the normalized newline character (as defined in Format.getNormalizedNewline()) that is used to replace any lineSeparator sequence found in the input.

bufferSize - the buffer size used to store characters read from the input.

whitespaceRangeStart - starting range of characters considered to be whitespace.

closeOnStop - indicates whether to automatically close the input when stop() is called

DefaultCharInputReader

public DefaultCharInputReader(char[] lineSeparator,
                              char normalizedLineSeparator,
                              int bufferSize,
                              int whitespaceRangeStart,
                              boolean closeOnStop)

Creates a new instance with the mandatory characters for handling newlines transparently.

Parameters:

lineSeparator - the sequence of characters that represent a newline, as defined in Format.getLineSeparator()

normalizedLineSeparator - the normalized newline character (as defined in Format.getNormalizedNewline()) that is used to replace any lineSeparator sequence found in the input.

bufferSize - the buffer size used to store characters read from the input.

whitespaceRangeStart - starting range of characters considered to be whitespace.

closeOnStop - indicates whether to automatically close the input when stop() is called

Method Detail

stop

public void stop()

Description copied from interface: CharInputReader

Stops the CharInputReader from reading characters from the Reader provided in CharInputReader.start(Reader) and closes it.

setReader

protected void setReader(java.io.Reader reader)

Description copied from class: AbstractCharInputReader

Passes the Reader provided in the AbstractCharInputReader.start(Reader) method to the extending class so it can begin loading characters from it.

Specified by:

setReader in class AbstractCharInputReader

Parameters:

reader - the Reader provided in AbstractCharInputReader.start(Reader)

reloadBuffer

public void reloadBuffer()

Copies a sequence of characters from the input into the AbstractCharInputReader.buffer, and updates the AbstractCharInputReader.length to the number of characters read.

Specified by:

reloadBuffer in class AbstractCharInputReader
