    my $v = Sisimai::RFC2045->is_encoded(\$e);  # 1

"decodeH(Array-Ref)"¶

decodeH() is a decoder method for getting the original string from MIME-Encoded string in email headers.

    my $r = '=?utf-8?B?55m954yr44Gr44KD44KT44GT?=';
    my $v = Sisimai::RFC2045->decodeH([$r]);

"decodeB(\String)"¶

"decodeB" is a decoder method for getting the original string from MIME Base64 encoded string.

    my $r = '44Gr44KD44O844KT';
    my $v = Sisimai::RFC2045->decodeB(\$r);

"decodeQ(\String)"¶

"decodeQ" is a decoder method for getting the original string from MIME quoted-printable encoded string.

    my $r = '=4e=65=6b=6f';
    my $v = Sisimai::RFC2045->decodeQ(\$r);

"parameter(String, String)"¶

parameter() returns the value of parameter in Content-Type header.

    my $r = 'Content-Type: multipart/mixed; boundary=Apple-Mail-1-526612466'; charset=utf8;
    print Sisimai::RFC2045->parameter($r, 'charset');  # utf8
    print Sisimai::RFC2045->parameter($r, 'boundary'); # Apple-Mail-1-526612466
    print Sisimai::RFC2045->parameter($r);             # multipart/mixed

"boundary(String, Integer)"¶

boundary() returns a boundary string from the value of Content-Type header.

    my $r = 'Content-Type: multipart/mixed; boundary=Apple-Mail-1-526612466';
    my $v = Sisimai::RFC2045->boundary($r);
    print $v;   # Apple-Mail-1-526612466
    print Sisimai::RFC2045->boundary($r, 0); # --Apple-Mail-1-526612466
    print Sisimai::RFC2045->boundary($r, 1); # --Apple-Mail-1-526612466--

"haircut(\String, Boolean)"¶

haircut() remove unused headers from multipart/* block.

"levelout(String, \String)"¶

"levelout" breaks multipart/* message block into each part and returns an array reference.

"makeflat(String, \String)"¶

"makeflat" makes flat multipart/* message: This method breaks multipart/* block into each part, remove parts which are not needed to parse a bounce message such as image/* MIME type, and decode an encoded text part (text/*, message/*) in a body of each part that has "Content-Transfer-Encoding" header and the value of the header is quoted-printabe, base64, or 7bit.
