Content type class java

Content type class java

This class represents a MIME ContentType value. It provides methods to parse a ContentType string into individual components and to generate a MIME style ContentType string.

Constructor Summary
ContentType () No-arg Constructor.
ContentType (java.lang.String s) Constructor that takes a Content-Type string.
ContentType (java.lang.String primaryType, java.lang.String subType, ParameterList list) Constructor.

Method Summary
java.lang.String	getBaseType () Return the MIME type string, without the parameters.
java.lang.String	getParameter (java.lang.String name) Return the specified parameter value.
ParameterList	getParameterList () Return a ParameterList object that holds all the available parameters.
java.lang.String	getPrimaryType () Return the primary type.
java.lang.String	getSubType () Return the subType.
boolean	match (ContentType cType) Match with the specified ContentType object.
boolean	match (java.lang.String s) Match with the specified content-type string.
void	setParameter (java.lang.String name, java.lang.String value) Set the specified parameter.
void	setParameterList (ParameterList list) Set a new ParameterList.
void	setPrimaryType (java.lang.String primaryType) Set the primary type.
void	setSubType (java.lang.String subType) Set the subType.
java.lang.String	toString () Retrieve a RFC2045 style string representation of this Content-Type.

ContentType

ContentType

Parameters: primaryType — primary type subType — subType list — ParameterList

ContentType

Constructor that takes a Content-Type string. The String is parsed into its constituents: primaryType, subType and parameters. A ParseException is thrown if the parse fails.

Parameters: s — the Content-Type string. Throws: ParseException — if the parse fails.

Method Detail

getPrimaryType

public java.lang.String getPrimaryType()

getSubType

public java.lang.String getSubType()

getBaseType

public java.lang.String getBaseType()

Return the MIME type string, without the parameters. The returned value is basically the concatenation of the primaryType, the ‘/’ character and the secondaryType.

getParameter

public java.lang.String getParameter(java.lang.String name)

getParameterList

Return a ParameterList object that holds all the available parameters. Returns null if no parameters are available.

setPrimaryType

public void setPrimaryType(java.lang.String primaryType)

Parameters: primaryType — primary type

setSubType

public void setSubType(java.lang.String subType)

Parameters: subType — the subType

setParameter

public void setParameter(java.lang.String name, java.lang.String value)

Parameters: name — parameter name value — parameter value

setParameterList

Parameters: list — ParameterList

toString

public java.lang.String toString()

Retrieve a RFC2045 style string representation of this Content-Type. Returns null if the conversion failed.

Overrides: toString in class java.lang.Object Returns: RFC2045 style string

match

Match with the specified ContentType object. This method compares only the primaryType and subType . The parameters of both operands are ignored.

For example, this method will return true when comparing the ContentTypes for «text/plain» and «text/plain; charset=foobar». If the subType of either operand is the special character ‘*’, then the subtype is ignored during the match. For example, this method will return true when comparing the ContentTypes for «text/plain» and «text/*»

Parameters: cType — ContentType to compare this against

match

public boolean match(java.lang.String s)

Match with the specified content-type string. This method compares only the primaryType and subType . The parameters of both operands are ignored.

For example, this method will return true when comparing the ContentType for «text/plain» with «text/plain; charset=foobar». If the subType of either operand is the special character ‘*’, then the subtype is ignored during the match. For example, this method will return true when comparing the ContentType for «text/plain» with «text/*»

Annotation Interface ContentType

Meta annotation, specifies that an annotation represents a content type, such as a time span or a frequency.

The following example shows how a temperature content type can be created and used.

First declare a temperature annotation using the ContentType annotation:

@MetadataDefinition @ContentType @Name("com.example.Temperature") @Label("Temperature") @Target(ElementType.FIELD) @Retention(RetentionPolicy.RUNTIME) public @interface Temperature

@Name("com.example.CPU") @Label("CPU") @Category(< "Hardware", "CPU" >) @Period("1 s") @StackTrace(false) static public class CPUEvent extends Event < @Label("ID") String id; @Temperature(Temperature.KELVIN) @Label("Temperature") float temperature; >public static void main(String. args) throws InterruptedException < FlightRecorder.addPeriodicEvent(CPUEvent.class, () -> < for (var cpu : listCPUs()) < CPUEvent event = new CPUEvent(); event.id = cpu.id(); event.temperature = cpu.temperature(); // in Kelvin event.commit(); >>); Thread.sleep(10_000); > 

void printTemperaturesInCelsius(Path file) throws IOException < for (RecordedEvent event : RecordingFile.readAllEvents(file)) < for (ValueDescriptor field : event.getEventType().getFields()) < for (AnnotationElement ae : field.getAnnotationElements()) < ContentType type = ae.getAnnotation(ContentType.class); if (type != null) < if (ae.getTypeName().equals("com.example.Temperature")) < double value = event.getDouble(field.getName()); String unit = (String) ae.getValue("value"); double celsius = switch (unit) < case "CELSIUS" ->value; case "KELVIN" -> value - 273.15; case "FAHRENHEIT" -> (value - 32) / 1.8; default -> throw new IllegalStateException("Unknown temperature unit '" + unit + "'"); >; System.out.println(celsius + " C"); > else < System.err.println("Can't format content type " + ae.getTypeName() + " for field " + field.getName()); >> > > > >
