Constructor Details

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
 String sContentSubType,
 @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 Details

getContentType

@Nonnull
public EMimeContentType getContentType()

Specified by:

getContentType in interface IMimeType

Returns:

The content type. Never null.

getContentSubType

@Nonnull
@Nonempty
public String getContentSubType()

Specified by:

getContentSubType in interface IMimeType

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!

See Also:

• IMimeType.getAsString(EMimeQuoting)
• IMimeType.getAsStringWithoutParameters()

addParameter

@Nonnull
public MimeType addParameter(@Nonnull @Nonempty
 String sAttribute,
 @Nonnull
 String sValue)

Add a parameter.

Parameters:

sAttribute - Parameter name. Must neither be null nor empty and must match MimeTypeParser.isToken(String).

sValue - The value to use. May not be null. Must not be a valid MIME token.

Returns:

this

removeAllParameters

@Nonnull
public EChange removeAllParameters()

Remove all existing parameters.

Returns:

EChange.CHANGED if at least one parameter was present

removeParameterWithName

@Nonnull
