SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
An interface which describes a region of an unspecified byte array. A Field may be used to access a data element stored at the same offset in many different byte arrays. Multiple Field instances can be used to create a template for mapping a record. For this reason, Field objects are often stored as static (class) variables in a record-mapping class.
Field objects are often constructed by a
DatatypeFactory
, which builds consecutive fields at adjoining
offsets in a template record.
