Detailed Description

An input stream for a contiguous piece of memory.

Constructor & Destructor Documentation

MemoryInputStream() [1/2]

CartoTypeCore::MemoryInputStream::MemoryInputStream ( const uint8_t *  aData, size_t  aLength  )

inline

Creates a memory input stream to read from data of aLength bytes starting at aData.

MemoryInputStream() [2/2]

CartoTypeCore::MemoryInputStream::MemoryInputStream ( const std::string &  aString )

inlineexplicit

Creates a memory input stream to read from a std::string.

Member Function Documentation

Copy()

std::unique_ptr< InputStream > CartoTypeCore::MemoryInputStream::Copy ( )

overridevirtual

Creates a copy of the stream.

Implements CartoTypeCore::InputStream.

StreamEnd()

bool CartoTypeCore::MemoryInputStream::StreamEnd ( ) const

inlineoverridevirtual

Returns whether the end of the stream has been reached.

Implements CartoTypeCore::InputStream.

StreamLength()

int64_t CartoTypeCore::MemoryInputStream::StreamLength ( )

inlineoverridevirtual

Returns the number of bytes in the stream.

Implements CartoTypeCore::InputStream.

StreamPosition()

int64_t CartoTypeCore::MemoryInputStream::StreamPosition ( )

inlineoverridevirtual

Returns the current position.

Implements CartoTypeCore::InputStream.

StreamRead()

void CartoTypeCore::MemoryInputStream::StreamRead ( const uint8_t *&  aPointer, size_t &  aLength  )

overridevirtual

Reads some data into a buffer owned by the InputStream object and returns a pointer to it in aPointer. Returns the number of bytes of data in aLength. This function will return at least one byte if there are bytes remaining in the stream. The pointer is valid until the next call to Read.

Implements CartoTypeCore::InputStream.

StreamSeek()

void CartoTypeCore::MemoryInputStream::StreamSeek ( int64_t  aPosition )

overridevirtual

Seeks to the specified position.

Implements CartoTypeCore::InputStream.
