Interface ColumnInfo

One attribute column's schema, copied out of the header.

interface ColumnInfo {
    index: number;
    name: string;
    nullable: boolean;
    type: ColumnType;
}

Properties

index: number

The column's ordinal. Attribute blobs are keyed by this, and AttrIndexInfo.columnIndex refers to it.

name: string

The attribute name, and what an AttrCondition.field must match.

nullable: boolean

Selects both how the attribute blob is decoded and what JS type an AttrCondition.value against this column may have.
