Class FileBackedOutputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    @Beta
@Deprecated(since="2022-12-01")
public final class FileBackedOutputStream
extends java.io.OutputStream
    Deprecated.
    The Google Guava Core Libraries are deprecated and will not be part of the AEM SDK after April 2023
    An OutputStream that starts buffering to a byte array, but switches to file buffering once the data reaches a configurable size.

    This class is thread-safe.

    Since:
    1.0

      Constructor Description
      FileBackedOutputStream​(int fileThreshold)
      Deprecated.
      Creates a new instance that uses the given file threshold, and does not reset the data when the ByteSource returned by asByteSource() is finalized.
      FileBackedOutputStream​(int fileThreshold, boolean resetOnFinalize)
      Deprecated.
      Creates a new instance that uses the given file threshold, and optionally resets the data when the ByteSource returned by asByteSource() is finalized.

      • FileBackedOutputStream

        public FileBackedOutputStream​(int fileThreshold)
        Deprecated.
        Creates a new instance that uses the given file threshold, and does not reset the data when the ByteSource returned by asByteSource() is finalized.
        Parameters:
        fileThreshold - the number of bytes before the stream should switch to buffering to a file

      • FileBackedOutputStream

        public FileBackedOutputStream​(int fileThreshold,
                              boolean resetOnFinalize)
        Deprecated.
        Creates a new instance that uses the given file threshold, and optionally resets the data when the ByteSource returned by asByteSource() is finalized.
        Parameters:
        fileThreshold - the number of bytes before the stream should switch to buffering to a file
        resetOnFinalize - if true, the reset() method will be called when the ByteSource returned by asByteSource() is finalized

      • getSupplier

        @Deprecated
public InputSupplier<java.io.InputStream> getSupplier()
        Deprecated.
        Use asByteSource() instead. This method is scheduled to be removed in Guava 16.0.
        Returns a supplier that may be used to retrieve the data buffered by this stream. This method returns the same object as asByteSource().

      • asByteSource

        public ByteSource asByteSource()
        Deprecated.
        Returns a readable ByteSource view of the data that has been written to this stream.
        Since:
        15.0

      • reset

        public void reset()
           throws java.io.IOException
        Deprecated.
        Calls close() if not already closed, and then resets this object back to its initial state, for reuse. If data was buffered to a file, it will be deleted.
        Throws:
        java.io.IOException - if an I/O error occurred while deleting the file buffer
