public class NativeInt8
extends NativeInteger

A descriptor for a byte which may be either signed or unsigned. The 4GL does not differentiate between the two types, but the native code may be sensitive to this. The type will be as LibraryManager.TYPE_SIGNED_INT8 if the value is negative and otherwise it will report as LibraryManager.TYPE_UNSIGNED_INT8.

Constructor Detail

NativeInt8

public NativeInt8()

Default constructor.

Method Detail

setValue

public void setValue(long value)

Assign the data element.

Overrides:

setValue in class NativeInteger

Parameters:

value - The new integer data element.

size

public int size()

Report the size (in bytes) of the native memory needed to store this instance.

This should never be called on the server, only on the client side.

Specified by:

size in class BaseNativeType

Returns:

The number of bytes needed.

readNative

protected void readNative(memptr ptr)

Worker method to read the primitive value from the first index position of the given memory buffer.

Specified by:

readNative in class NativePrimitive

Parameters:

ptr - The memory buffer to reference.

writeNative

protected void writeNative(memptr ptr)

Worker method to write the primitive value to the first index position of the given memory buffer.

Specified by:

writeNative in class NativePrimitive

Parameters:

ptr - The memory buffer to reference.
