Method Detail

reserve

public void reserve(int tagId,
                    int length)

Specifies tagId and size of the tag value. All tags should be reserved in order like in generated message. Use MessageStructure.VARIABLE_LENGTH to define the tag value that could be increased dynamically for concrete parameter. Keep in mind, this will slow performance and spawn new Objects in runtime. Reserved field will be added to the end of the structure.

Parameters:

tagId - tagId

length - required amount of bytes for value or MessageStructure.VARIABLE_LENGTH.

reserveString

public void reserveString(int tagId)

reserveString

public void reserveString(int tagId,
                          int length)

reserveLong

public void reserveLong(int tagId,
                        int length)

reserve

public void reserve(int position,
                    int tagId,
                    int length)

Specifies tagId and size of the tag value. Reserved field will be inserted at specified position.

Parameters:

position - position to insent the tag

tagId - tagId

length - required amount of bytes for value or MessageStructure.VARIABLE_LENGTH.

reserveString

public void reserveString(int position,

reserveLong

public void reserveLong(int position,
                        int tagId,
                        int length)
