Method Detail

openStream

public java.io.Reader openStream()

Description copied from class: CharSource

Opens a new Reader for reading from this source. This method should return a new, independent reader each time it is called.

The caller is responsible for ensuring that the returned reader is closed.

Specified by:

openStream in class CharSource

read

public java.lang.String read()

Description copied from class: CharSource

Reads the contents of this source as a string.

Overrides:

read in class CharSource

isEmpty

public boolean isEmpty()

Description copied from class: CharSource

Returns whether the source has zero chars. The default implementation is to open a stream and check for EOF.

Overrides:

isEmpty in class CharSource

lines

private java.lang.Iterable<java.lang.String> lines()

Returns an iterable over the lines in the string. If the string ends in a newline, a final empty string is not included to match the behavior of BufferedReader/LineReader.readLine().

readFirstLine

public java.lang.String readFirstLine()

Description copied from class: CharSource

Reads the first link of this source as a string. Returns null if this source is empty.

Like BufferedReader, this method breaks lines on any of \n, \r or \r\n, does not include the line separator in the returned line and does not consider there to be an extra empty line at the end if the content is terminated with a line separator.

Overrides:

readFirstLine in class CharSource

readLines

public ImmutableList<java.lang.String> readLines()

Description copied from class: CharSource

Reads all the lines of this source as a list of strings. The returned list will be empty if this source is empty.

Like BufferedReader, this method breaks lines on any of \n, \r or \r\n, does not include the line separator in the returned lines and does not consider there to be an extra empty line at the end if the content is terminated with a line separator.

Overrides:

readLines in class CharSource

readLines

public <T> T readLines(LineProcessor<T> processor)
                throws java.io.IOException

Description copied from class: CharSource

Reads lines of text from this source, processing each line as it is read using the given processor. Stops when all lines have been processed or the processor returns false and returns the result produced by the processor.

Like BufferedReader, this method breaks lines on any of \n, \r or \r\n, does not include the line separator in the lines passed to the processor and does not consider there to be an extra empty line at the end if the content is terminated with a line separator.

Overrides:

readLines in class CharSource

Throws:

java.io.IOException - if an I/O error occurs in the process of reading from this source or if processor throws an IOException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
