Constructor Detail

FieldHeader

public FieldHeader(FieldHeader parent,
                   String fieldName,
                   DataType dataType,
                   int[] dims,
                   long positionBuffer,
                   long expectedNumberOfBytes)

Constructs new serializer field header

Parameters:

parent - the optional parent field header (for cascaded objects)

fieldName - the clear text field name description

dataType - the data type of that field

dims - array with length indicating the number-of-dimensions and indices the length of each dimension

positionBuffer - the position from which the actual data can be parsed onwards

expectedNumberOfBytes - the expected number of bytes to skip the data block
