Method Detail

calculateFieldSize

public static <T> int calculateFieldSize(FudgeTaxonomy taxonomy,
                                         Short ordinal,
                                         String name,
                                         FudgeFieldType<T> type,
                                         T value)

Calculates the size of a field (field header and value payload) in the Fudge stream in bytes.

The calculation takes account of the value being reduced to fit in a smaller space.

Type Parameters:

T - the underlying Java type of the field data

Parameters:

taxonomy - the taxonomy in use, null if no taxonomy

ordinal - the field ordinal, null if no ordinal

name - the field name, null if no name

type - the Fudge field type, not null

value - the field value

Returns:

the number of bytes
