Field Detail

value

protected float value

The stored value.

Constructor Detail

NativeFloat

public NativeFloat()

Default constructor.

Method Detail

getValue

public float getValue()

Access the data element.

Returns:

The floating point data element.

setValue

public void setValue(float value)

Assign the data element.

Parameters:

value - The new floating point data element.

readExternal

public void readExternal(java.io.ObjectInput in)
                  throws java.io.IOException,
                         java.lang.ClassNotFoundException

Replacement for the default object reading method. The latest state is read from the input source. The parent's state is read first.

Specified by:

readExternal in interface java.io.Externalizable

Overrides:

readExternal in class BaseNativeType

Parameters:

in - The input source from which fields will be restored.

Throws:

java.io.IOException - In case of I/O errors.

java.lang.ClassNotFoundException - If payload can't be instantiated.

writeExternal

public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException

Replacement for the default object writing method. The latest state is written to the output destination. The parent's state is written first.

Specified by:

writeExternal in interface java.io.Externalizable

Overrides:

writeExternal in class BaseNativeType

Parameters:

out - The output destination to which fields will be saved.

Throws:

java.io.IOException - In case of I/O errors.

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.
