Additional Inherited Members |
Abstract base class for all the Unicode character input stream implementation classes. Implements the body idiom from the handle-body pattern.
|
inlinevirtual |
Destructor.
|
inlineprotected |
Constructor.
|
virtual |
Acquires the synchronization mechanism provided by a stream concrete implementation. The acquire() member function returns a handle to the UTF-16 character stream that should be used for input operation after acquiring the synchronization mechanism.
Reimplemented in RWTInputStreamLockImp< RWUCharInputStream, RWFilteredUCharInputStreamImp >.
|
pure virtual |
Reads a single UTF-16 character from the stream.
Implemented in RWTInputStreamLockImp< RWUCharInputStream, RWFilteredUCharInputStreamImp >, RWUCharFromUTF8ByteInputStreamImp, RWUCharFromByteInputStreamImp, and RWFilteredUCharInputStreamImp.
|
pure virtual |
Reads an array of UTF-16 characters from the stream. The array must be pre-allocated to contain at least numUChars elements. The function returns the actual number of UTF-16 characters read from the stream.
unicodeArray | A pointer to the first element of the array. |
numUChars | The number of UTF-16 characters to be read from the stream. |
Implemented in RWTInputStreamLockImp< RWUCharInputStream, RWFilteredUCharInputStreamImp >, RWUCharFromUTF8ByteInputStreamImp, RWUCharFromByteInputStreamImp, and RWFilteredUCharInputStreamImp.
|
pure virtual |
Reads UTF-16 characters from the stream until the last UTF-16 character read is equal to delim, or maxSize UTF-16 characters have been read, or the end of the input sequence is reached. The UTF-16 characters read are stored in unicodeArray. The function returns the actual number of UTF-16 characters read from the stream.
unicodeArray | A pointer to the array receiving the UTF-16 characters extracted from the stream. |
maxSize | The maximum number of UTF-16 characters to be read. |
delim | The UTF-16 character used as a delimiter. |
Implemented in RWUCharFromUTF8ByteInputStreamImp, RWUCharFromByteInputStreamImp, RWFilteredUCharInputStreamImp, and RWSynchronizedUCharInputStreamImp.
|
inlinevirtual |
Releases the synchronization mechanism provided by a stream concrete implementation.
Reimplemented in RWTInputStreamLockImp< RWUCharInputStream, RWFilteredUCharInputStreamImp >.
