AbstractDecimal.AbstractDecimalSerializer

public AbstractDecimal.AbstractDecimalSerializer(int decimals,
                                         Class<V> type)

Method Detail

construct

protected abstract V construct(long format,
          int decimals)

read

public V read(ScanBuffer buffer)

Description copied from interface: AttributeSerializer

Reads an attribute from the given ReadBuffer.

It is expected that this read operation adjusts the position in the ReadBuffer to after the attribute value.

Specified by:

read in interface AttributeSerializer<V extends AbstractDecimal>

Parameters:

buffer - ReadBuffer to read attribute from

Returns:

Read attribute

write

public void write(WriteBuffer buffer,
         V attribute)

Description copied from interface: AttributeSerializer

Writes the attribute value to the given WriteBuffer.

It is expected that this write operation adjusts the position in the WriteBuffer to after the attribute value.

Specified by:

write in interface AttributeSerializer<V extends AbstractDecimal>

Parameters:

buffer - WriteBuffer to write attribute to

attribute - Attribute to write to WriteBuffer

readByteOrder

public V readByteOrder(ScanBuffer buffer)

Description copied from interface: OrderPreservingSerializer

Reads an attribute from the given ReadBuffer assuming it was written in byte order.

It is expected that this read operation adjusts the position in the ReadBuffer to after the attribute value.

Specified by:

readByteOrder in interface OrderPreservingSerializer<V extends AbstractDecimal>

Parameters:

buffer - ReadBuffer to read attribute from

Returns:

Read attribute

writeByteOrder

public void writeByteOrder(WriteBuffer buffer,
                  V attribute)

Description copied from interface: OrderPreservingSerializer

Writes the attribute value to the given WriteBuffer such that the byte order of the result is equal to the natural order of the attribute.

It is expected that this write operation adjusts the position in the WriteBuffer to after the attribute value.

Specified by:

writeByteOrder in interface OrderPreservingSerializer<V extends AbstractDecimal>

Parameters:

buffer - WriteBuffer to write attribute to

attribute - Attribute to write to WriteBuffer

verifyAttribute

public void verifyAttribute(V value)

Description copied from interface: AttributeHandler

Verifies the given (not-null) attribute value is valid. Throws an IllegalArgumentException if the value is invalid, otherwise simply returns.

Specified by:

verifyAttribute in interface AttributeHandler<V extends AbstractDecimal>

Parameters:

value - to verify

convert

public V convert(Object value)

Description copied from interface: AttributeHandler

Converts the given (not-null) value to the expected datatype V. The given object will NOT be of type V. Throws an IllegalArgumentException if it cannot be converted.

Specified by:

convert in interface AttributeHandler<V extends AbstractDecimal>

Parameters:

value - to convert

Returns:

converted to expected datatype
