The base class for streams that write data to some kind of destination.
Input and output streams are used throughout the library - subclasses can override some or all of the virtual functions to implement their behaviour.

Destructor.
Some subclasses might want to do things like call flush() during their destructors.

If the stream is using a buffer, this will ensure it gets written out to the destination.
Implemented in juce::FileOutputStream, juce::MemoryOutputStream, and juce::GZIPCompressorOutputStream.
Tries to move the stream's output position.
Not all streams will be able to seek to a new position - this will return false if it fails to work.
Implemented in juce::FileOutputStream, juce::MemoryOutputStream, and juce::GZIPCompressorOutputStream.

Returns the stream's current position.

pure virtual |
Writes a block of data to the stream.
When creating a subclass of OutputStream, this is the only write method that needs to be overloaded - the base class has methods for writing other types of data which use this to do the work.
dataToWrite | the target buffer to receive the data. This must not be null. |
numberOfBytes | the number of bytes to write. |
Implemented in juce::FileOutputStream, juce::MemoryOutputStream, and juce::GZIPCompressorOutputStream.
Referenced by juce::AiffAudioFormatWriter::write(), and juce::WavAudioFormatWriter::write().
Writes a single byte to the stream.

Referenced by juce::XmlDocument::getDocumentElement(), juce::InputStream::readNextLine(), juce::InputStream::readString(), and juce::XmlElement::writeToStream().
Writes a boolean to the stream as a single byte.
This is encoded as a binary byte (not as text) with a value of 1 or 0.
Definition at line 66 of file juce_OutputStream.cpp.
Writes a 16-bit integer to the stream in a little-endian byte order.
This will write two bytes to the stream: (value & 0xff), then (value >> 8).

Referenced by juce::FileOutputStream::writeRepeatedByte().
Writes a condensed binary encoding of a 32-bit integer.
If you're storing a lot of integers which are unlikely to have very large values, this can save a lot of space, because values under 0xff will only take up 2 bytes, under 0xffff only 3 bytes, etc.
The format used is: number of significant bytes + up to 4 bytes in little-endian order.
Definition at line 110 of file juce_OutputStream.cpp.
Stores a string in the stream in a binary format.
This isn't the method to use if you're trying to append text to the end of a text-file! It's intended for storing a string so that it can be retrieved later by InputStream::readString().
It writes the string to the stream as UTF8, including the null termination character.
For appending text to a file, instead use writeText, or operator<<

Writes a string of text to the stream.
It can either write the text as UTF-8 or UTF-16, and can also add the UTF-16 byte-order-mark bytes (0xff, 0xfe) to indicate the endianness (these should only be used at the start of a file).
If lineEndings is nullptr, then line endings in the text won't be modified. If you pass "\\n" or "\\r\\n" then this function will replace any existing line feeds.
