Properties​

delimiters​

readonly delimiters: Delimiters

The four delimiters this header put into force - the set its own fields, and every record after it, were read with.

A stream may carry several messages (H … L) and each header declares its own set, so on a multi-header stream these can differ between headers; AstmMessage.delimiters is the first header's. When a later header cannot declare a usable set, the set already in force is kept and reported here (with an ASTM_RECORD_UNREADABLE_REDECLARATION warning) rather than a guessed one.

fields​

readonly fields: readonly AstmField[]

The record's fields. fields[0] is the type-letter field; data fields are 1-indexed after it.

Inherited from​

RecordBase.fields

rawLine​

readonly rawLine: string

The header's exact wire text (terminator excluded), kept as provenance: the delimiters are read from this raw text, never from RecordBase.fields.

It is not what the serializer emits from. To change a header field, edit RecordBase.fields - fields[0] is the type letter, fields[1] is the delimiter declaration, and the header's ASTM data fields follow from fields[2]. Editing this string instead has no effect on emit.

recordIndex​

readonly recordIndex: number

0-based ordinal of the record within the message.

Inherited from​

RecordBase.recordIndex

type​

readonly type: "H"

The record's raw type letter.

Overrides​

RecordBase.type
