![]() | |
OutputStream () | |
Writes data to an internal memory buffer, which grows as required.
The data that was written into the stream can then be accessed later as a contiguous block of memory.
MemoryOutputStream::MemoryOutputStream | ( | size_t | initialSize = 256 | ) |
Creates an empty memory stream, ready to be written into.
initialSize | the intial amount of capacity to allocate for writing into |
MemoryOutputStream::MemoryOutputStream | ( | MemoryBlock & | memoryBlockToWriteTo, |
bool | appendToExistingBlockContent | ||
) |
Creates a memory stream for writing into into a pre-existing MemoryBlock object.
Note that the destination block will always be larger than the amount of data that has been written to the stream, because the MemoryOutputStream keeps some spare capactity at its end. To trim the block's size down to fit the actual data, call flush(), or delete the MemoryOutputStream.
memoryBlockToWriteTo | the block into which new data will be written. |
appendToExistingBlockContent | if this is true, the contents of the block will be kept, and new data will be appended to it. If false, the block will be cleared before use |
MemoryOutputStream::MemoryOutputStream | ( | void * | destBuffer, |
size_t | destBufferSize | ||
) |
Creates a MemoryOutputStream that will write into a user-supplied, fixed-size block of memory. When using this mode, the stream will write directly into this memory area until it's full, at which point write operations will fail.
MemoryOutputStream::~MemoryOutputStream | ( | ) |
Destructor. This will free any data that was written to it.
bool MemoryOutputStream::appendUTF8Char | ( | juce_wchar | character | ) |
Appends the utf-8 bytes for a unicode character
|
overridevirtual |
If the stream is writing to a user-supplied MemoryBlock, this will trim any excess capacity off the block, so that its length matches the amount of actual data that has been written so far.
Implements juce::OutputStream.
|
noexcept |
Returns a pointer to the data that has been written to the stream.
|
inlinenoexcept |
Returns the number of bytes of data that have been written to the stream.
MemoryBlock MemoryOutputStream::getMemoryBlock | ( | ) | const |
Returns a copy of the stream's data as a memory block.
|
inlineoverridevirtual |
void MemoryOutputStream::preallocate | ( | size_t | bytesToPreallocate | ) |
Increases the internal storage capacity to be able to contain at least the specified amount of data without needing to be resized.
|
noexcept |
Resets the stream, clearing any data that has been written to it so far.
|
overridevirtual |
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.
Implements juce::OutputStream.
String MemoryOutputStream::toString | ( | ) | const |
Attempts to detect the encoding of the data and convert it to a string.
String MemoryOutputStream::toUTF8 | ( | ) | const |
Returns a String created from the (UTF8) data that has been written to the stream.
|
overridevirtual |
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. |
Implements juce::OutputStream.
|
overridevirtual |
Reads data from an input stream and writes it to this stream.
source | the stream to read from |
maxNumBytesToWrite | the number of bytes to read from the stream (if this is less than zero, it will keep reading until the input is exhausted) |
Reimplemented from juce::OutputStream.
|
overridevirtual |
Writes a byte to the output stream a given number of times.
Reimplemented from juce::OutputStream.
