Buffer

Region of native memory that can be read and written.

Buffer does not provide any kind of thread-safety and external synchronization is required if concurrent access is needed.

Attempting to alter the buffer while it is in use by SQLite will throw an IllegalStateException.

The Buffer must be closed once no longer needed to release allocated resources.

Types

Provides factory functions for allocating a Buffer.

Size of the memory region in bytes.

open override fun close()

Releases allocated resources.

fun read(destination: ByteArray, size: Int = destination.size, sourceOffset: Long = 0, destinationOffset: Int = 0)

Reads size bytes from the native memory block into destination.

Reads size bytes from the native memory block and returns a ByteArray holding them.

Reads at most Int.MAX_VALUE bytes from this buffer.

Reads all bytes from this buffer.

fun resize(newSize: Int)

fun resize(newSize: Long)

Resizes this buffer to newSize. If allocation fails, this buffer stays untouched.

fun write(source: ByteArray, size: Int, sourceOffset: Int = 0, destinationOffset: Long = 0)

Writes size bytes from source into the native memory block.
