Constructor Detail

MimeType

public MimeType(@Nonnull
                IMimeType aOther)

Kind of a copy constructor

Parameters:

aOther - The other object to copy the data from

MimeType

public MimeType(@Nonnull
                EMimeContentType eContentType,
                @Nonnull @Nonempty
                String sContentSubType)

Constructor without parameters. To construct the MIME type "text/xml" you need to pass EMimeContentType.TEXT and the String "xml" to this constructor.

Parameters:

eContentType - MIME content type. May not be null.

sContentSubType - MIME content sub type. May neither be null nor empty.

MimeType

public MimeType(@Nonnull
                EMimeContentType eContentType,
                @Nonnull @Nonempty

                @Nullable
                Collection<? extends MimeTypeParameter> aParameters)

Constructor without parameters. To construct the MIME type "text/xml" you need to pass EMimeContentType.TEXT and the String "xml" to this constructor.

Parameters:

eContentType - MIME content type. May not be null.

sContentSubType - MIME content sub type. May neither be null nor empty.

aParameters - MIME type parameters. May be null or empty.

Method Detail

Returns:

The content sub type. Never null.

getAsString

@Nonnull
@Nonempty
public String getAsString(@Nonnull
                          EMimeQuoting eQuotingAlgorithm)

Description copied from interface: IMimeType

Get the MIME type including all parameters as a single string. The specified quoting algorithm is used to quote parameter values (if necessary).

Specified by:

getAsString in interface IMimeType

Parameters:

eQuotingAlgorithm - Quoting algorithm to be used

Returns:

The combined string to be used as text representation: contentType '/' subType ( ';' parameterName '=' parameterValue )*

See Also:

IMimeType.getAsStringWithoutParameters(), IMimeType.getParametersAsString(EMimeQuoting)

getAsStringWithoutParameters

@Nonnull
public String getAsStringWithoutParameters()

Specified by:

getAsStringWithoutParameters in interface IMimeType

Returns:

The combined string to be used as text representation but without the parameters: contentType '/' subType

See Also:

IMimeType.getAsString()

getParametersAsString

@Nonnull
public String getParametersAsString(@Nonnull
                                    EMimeQuoting eQuotingAlgorithm)

Description copied from interface: IMimeType

Get all MIME type parameters as a single string but without the leading content and sub type. The specified quoting algorithm is used to quote parameter values.

Specified by:

getParametersAsString in interface IMimeType

Parameters:

eQuotingAlgorithm - Quoting algorithm to be used

Returns:

The combined string to be used as text representation: (';' parameterName '=' parameterValue )* . If no parameters are present, an empty String is returned!
