Method Details

getPosition

public int getPosition()

Description copied from class: BinaryOutput

Returns this buffer's position.

Overrides:

getPosition in class BinaryOutput

getAddress

public org.graalvm.nativeimage.c.type.CCharPointer getAddress()

Returns an address of an off-heap memory segment containing the marshalled data.

write

public void write(int b)

Description copied from class: BinaryOutput

Writes the lowest byte of the argument as a single byte value. The buffer position is incremented by 1.

Specified by:

write in class BinaryOutput

write

public void write(byte[] b,
 int off,
 int len)

Description copied from class: BinaryOutput

Writes len bytes from the byte array starting at offset off. The buffer position is incremented by len.

Specified by:

write in class BinaryOutput

skip

public void skip(int numberOfBytes)

Description copied from class: BinaryOutput

Reserves a buffer space. The reserved space can be used for out parameters.

Specified by:

skip in class BinaryOutput

Parameters:

numberOfBytes - number of bytes to reserve.

close

public void close()

Closes the buffer and frees off-heap allocated resources.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

create

public static BinaryOutput.CCharPointerBinaryOutput create(int initialSize)

Creates a new buffer backed by an off-heap memory segment. The buffer initial size is initialSize.
