PropertyEntryFixedLength
Overview
PropertyEntryFixedLength represents a single 16-byte record from a MAPI fixed-length property stream. Each record encodes a property tag (type code in the lower 16 bits, property ID in the upper 16 bits), an access-control flags field, and an 8-byte raw value whose interpretation depends on the property type. Instances are produced exclusively by MsgReader.iter_top_level_fixed_length_properties() and are read-only value objects.

| Property | Type | Description |
|---|---|---|
property_tag | int | Full 32-bit property tag: upper 16 bits = property ID, lower 16 bits = property type code. |
flags | int | Access-control flags bitmask (PROPATTR_MANDATORY = 0x1, PROPATTR_READABLE = 0x2, PROPATTR_WRITABLE = 0x4). |
value | bytes | 8-byte raw value whose layout is determined by the property type encoded in property_tag. |
Methods
is_mandatory() -> bool
Returns True if the PROPATTR_MANDATORY flag (bit 0) is set in self.flags.
is_readable() -> bool
Returns True if the PROPATTR_READABLE flag (bit 1) is set in self.flags.
is_writable() -> bool
Returns True if the PROPATTR_WRITABLE flag (bit 2) is set in self.flags.
