Method Detail

read

public Character 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<Character>

Parameters:

buffer - ReadBuffer to read attribute from

Returns:

Read attribute

write

public void write(WriteBuffer out,
         Character 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<Character>

Parameters:

out - WriteBuffer to write attribute to

attribute - Attribute to write to WriteBuffer

readByteOrder

public Character 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<Character>

Parameters:

buffer - ReadBuffer to read attribute from

Returns:

Read attribute

writeByteOrder

public void writeByteOrder(WriteBuffer buffer,
                  Character 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<Character>

Parameters:

buffer - WriteBuffer to write attribute to

attribute - Attribute to write to WriteBuffer

char2short

public static final short char2short(char c)

short2char

public static final char short2char(short s)

verifyAttribute

public void verifyAttribute(Character 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<Character>

Parameters:

value - to verify

convert

public Character 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<Character>

Parameters:

value - to convert

Returns:

converted to expected datatype
