Class CharSink

java.lang.Object
com.google.common.io.CharSink
All Implemented Interfaces:
OutputSupplier<Writer>
@Deprecated(since="2022-12-01") public abstract class CharSink extends Object implements OutputSupplier<Writer>
Deprecated.
The Google Guava Core Libraries are deprecated and will not be part of the AEM SDK after April 2023
A destination to which characters can be written, such as a text file. Unlike a Writer, a CharSink is not an open, stateful stream that can be written to and closed. Instead, it is an immutable supplier of Writer instances.

CharSink provides two kinds of methods:

  • Methods that return a writer: These methods should return a new, independent instance each time they are called. The caller is responsible for ensuring that the returned writer is closed.
  • Convenience methods: These are implementations of common operations that are typically implemented by opening a writer using one of the methods in the first category, doing something and finally closing the writer that was opened.

Any ByteSink may be viewed as a CharSink with a specific character encoding using ByteSink.asCharSink(Charset). Characters written to the resulting CharSink will written to the ByteSink as encoded bytes.

Since:
14.0

    • openStream

      public abstract Writer openStream() throws IOException
      Deprecated.
      Opens a new Writer for writing to this sink. This method should return a new, independent writer each time it is called.

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

      Throws:
      IOException - if an I/O error occurs in the process of opening the writer

    • getOutput

      @Deprecated public final Writer getOutput() throws IOException
      Deprecated.
      This method is only provided for temporary compatibility with the OutputSupplier interface and should not be called directly. Use openStream() instead.
      This method is a temporary method provided for easing migration from suppliers to sources and sinks.
      Specified by:
      getOutput in interface OutputSupplier<Writer>
      Throws:
      IOException
      Since:
      15.0

    • openBufferedStream

      public Writer openBufferedStream() throws IOException
      Deprecated.
      Opens a new buffered Writer for writing to this sink. The returned stream is not required to be a BufferedWriter in order to allow implementations to simply delegate to openStream() when the stream returned by that method does not benefit from additional buffering. This method should return a new, independent writer each time it is called.

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

      Throws:
      IOException - if an I/O error occurs in the process of opening the writer
      Since:
      15.0 (in 14.0 with return type BufferedWriter)

    • write

      public void write(CharSequence charSequence) throws IOException
      Deprecated.
      Writes the given character sequence to this sink.
      Throws:
      IOException - if an I/O error in the process of writing to this sink

    • writeLines

      public void writeLines(Iterable<? extends CharSequence> lines) throws IOException
      Deprecated.
      Writes the given lines of text to this sink with each line (including the last) terminated with the operating system's default line separator. This method is equivalent to writeLines(lines, System.getProperty("line.separator")).
      Throws:
      IOException - if an I/O error occurs in the process of writing to this sink

    • writeLines

      public void writeLines(Iterable<? extends CharSequence> lines, String lineSeparator) throws IOException
      Deprecated.
      Writes the given lines of text to this sink with each line (including the last) terminated with the given line separator.
      Throws:
      IOException - if an I/O error occurs in the process of writing to this sink

    • writeFrom

      public long writeFrom(Readable readable) throws IOException
      Deprecated.
      Writes all the text from the given Readable (such as a Reader) to this sink. Does not close readable if it is Closeable.
      Throws:
      IOException - if an I/O error occurs in the process of reading from readable or writing to this sink
