PartBuilder
in package
Holds generic/all purpose information about a part while it's being parsed.
The class holds:
- a HeaderContainer to hold headers
- stream positions (part start/end positions, content start/end)
- the message's psr7 stream and a resource handle created from it (held only for a top-level PartBuilder representing the message, child PartBuilders do not duplicate/hold a separate stream).
More specific information a parser needs to keep about a message as it's parsing it should be stored in its ParserPartProxy.

Properties
$headerContainer
private
PartHeaderContainer
$headerContainer
The parsed part's headers.
$messageHandle
private
resource
$messageHandle
= null
the raw message input stream handle constructed from $messageStream or null for a child part
$messageStream
private
StreamInterface
$messageStream
= null
the raw message input stream for a message, or null for a child part.
$parent
private
ParserPartProxy
$parent
= null
The parent ParserPartProxy.
$streamContentEndPos
private
int
$streamContentEndPos
= null
The offset read end position in the message's stream for the end of this part's content (body).
$streamContentStartPos
private
int
$streamContentStartPos
= null
The offset read start position in the message's stream for the beginning of this part's content (body).
$streamPartEndPos
private
int
$streamPartEndPos
= null
The offset read end position for this part. If the part is a multipart mime part, the end position is after all of this parts children.
$streamPartStartPos
private
int
$streamPartStartPos
= null
The offset read start position for this part (beginning of headers) in the message's stream.
