Method Detail

serialize

protected abstract <T extends N> void serialize(List<T> list,
                                                io.netty.buffer.ByteBuf nlriByteBuf)

Serializes specific numeric operand type depending on the length field value.

Parameters:

list - of operands to be serialized

nlriByteBuf - where the operands will be serialized

toString

protected abstract <T extends N> String toString(List<T> list)

create

public final NumericOperand create(Set<String> operandValues)

Description copied from class: AbstractOperandParser

Creates operand from a set of operand values.

Specified by:

create in class AbstractOperandParser<NumericOperand>

Parameters:

operandValues - set of operand values

Returns:

specific type of operand

serialize

public final void serialize(NumericOperand operand,
                            int length,
                            boolean endOfList,
                            io.netty.buffer.ByteBuf buffer)

Description copied from class: AbstractOperandParser

Serializes operand to bytes.

Specified by:

serialize in class AbstractOperandParser<NumericOperand>

Parameters:

operand - operand to be serialized

length - value of the 'length' field

endOfList - if this operand is at the end of the list

buffer - where the operand will be serialized to

parse

public final NumericOperand parse(byte operand)

Description copied from class: AbstractOperandParser

Parses operand from byte value.

Specified by:

parse in class AbstractOperandParser<NumericOperand>

Parameters:

operand - byte representation of an operand

Returns:

operand object

toString

public String toString(NumericOperand operand,
                       boolean isFirst)

Description copied from class: AbstractOperandParser

Creates a string representation of the operand. E.g. : 'and does not match'

Specified by:

toString in class AbstractOperandParser<NumericOperand>

Parameters:

operand - operand

isFirst - true if this operand is the first in list of operands

Returns:

String representation of the operand
