const PString fieldValue 
)

Parameters:
fieldName  MIME field name
fieldValue  MIME field value

bool PMIMEInfo::AddMIME ( const PString line  ) 

Add a MIME field given a "name: value" format string.

Note that if the field name was already in the MIME dictionary then this will append the new value after a '\n' character to the previous value.

Returns:
true is a field was added.

PBoolean PMIMEInfo::Contains ( const PString &(*)()  key  )  const [inline]

Determine if the specified key is present in the MIME information set.

Returns:
true if the MIME variable is present.
Parameters:
key  Key into MIME dictionary to get info.

PBoolean PMIMEInfo::Contains ( const PCaselessString key  )  const [inline]

Determine if the specified key is present in the MIME information set.

Returns:
true if the MIME variable is present.
Parameters:
key  Key into MIME dictionary to get info.

PBoolean PMIMEInfo::Contains ( const PString key  )  const [inline]

Determine if the specified key is present in the MIME information set.

Returns:
true if the MIME variable is present.
Parameters:
key  Key into MIME dictionary to get info.

PBoolean PMIMEInfo::Contains ( const char *  key  )  const [inline]

Determine if the specified key is present in the MIME information set.

Returns:
true if the MIME variable is present.
Parameters:
key  Key into MIME dictionary to get info.

static const PString& PMIMEInfo::ContentDescriptionTag (  )  [static]

static const PString& PMIMEInfo::ContentDispositionTag (  )  [static]

static const PString& PMIMEInfo::ContentIdTag (  )  [static]

static const PString& PMIMEInfo::ContentTransferEncodingTag (  )  [static]

static const PString& PMIMEInfo::ContentTypeTag (  )  [static]

bool PMIMEInfo::DecodeMultiPartList ( PMultiPartList parts,
const PString body,
const PString &(*)()  key = ContentTypeTag 
) const [inline]

Decode parts from a multipart body using the field value.

Parameters:
parts  Extracted parts.
body  Body to decode
key  MIME key for multipart info

bool PMIMEInfo::DecodeMultiPartList ( PMultiPartList parts,
const PString body,
const PString key 
) const

Decode parts from a multipart body using the field value.

Parameters:
parts  Extracted parts.
body  Body to decode
key  MIME key for multipart info

bool PMIMEInfo::GetComplex ( const PString &(*)()  key,
PStringToString info 
) const [inline]

Parameters:
key  Key into MIME dictionary to get info.
info  Dictionary of information from field

bool PMIMEInfo::GetComplex ( const PString key,
PStringToString info 
) const [inline]

Get a complex MIME field.

This will parse a complex MIME field of the general form:

key: base-value;tag1=token;tag2="string";tag3 key: <base-value>;tag1=token;tag2="string";tag3

The base-value will be placed in the dictionary where the key is the empty string. If the base-value is quoted with '<', '>' brackets then the brackets are removed. Note that the string "<>" can be used to have an empty base-value but a field starting with a ';' is illegal and this function will return false.

Each tag will be the key for it's entry in the dictionary, if that tag has no '=' sign then it will have an empty string as its value. If the tag value is quoted using '"', then the RFC822 rules are applied and the quotes and '\' charcters removed.

IF there are multiple "key" entries in the MIME, or there is an entry of the form:

key: <base-value>;tag=token, <base-value1>, <base-value2>;tag=token

then the first entry wil be as described above. All subsequent entries are includedin the dictionary with the key names having the string "n:" prepended, e.g. "1:" would be "base-value1", "2:tag" would be the tag value on the third entry.

Returns true if the field exists and base-value is non-empty or quoted.

Parameters:
key  Key into MIME dictionary to get info.
info  Dictionary of information from field

static PString PMIMEInfo::GetContentType ( const PString fileType  )  [static]

This is primarily used by the standard operator<< function.

Parameters:
strm  Stream to print the object into.

Reimplemented from PAbstractDictionary.

PBoolean PMIMEInfo::Read ( PInternetProtocol socket  ) 

Read MIME information from the socket.

Returns:
true if the MIME information was successfully read.
