Method Detail

_writeText

protected String _writeText(T property)

Description copied from class: ICalPropertyScribe

Marshals a property's value to a string.

Specified by:

_writeText in class ICalPropertyScribe<T extends ListProperty<V>>

Parameters:

property - the property

Returns:

the marshalled value

_parseText

protected T _parseText(String value,
           ICalDataType dataType,
           ICalParameters parameters,
           List<Warning> warnings)

Description copied from class: ICalPropertyScribe

Unmarshals a property from a plain-text iCalendar data stream.

Specified by:

_parseText in class ICalPropertyScribe<T extends ListProperty<V>>

Parameters:

value - the value as read off the wire

dataType - the data type of the property value. The property's VALUE parameter is used to determine the data type. If the property has no VALUE parameter, then this parameter will be set to the property's default datatype. Note that the VALUE parameter is removed from the property's parameter list after it has been read.

parameters - the parsed parameters. These parameters will be assigned to the property object once this method returns. Therefore, do not assign any parameters to the property object itself whilst inside of this method, or else they will be overwritten.

warnings - allows the programmer to alert the user to any note-worthy (but non-critical) issues that occurred during the unmarshalling process

Returns:

the unmarshalled property object

_writeXml

protected void _writeXml(T property,
             XCalElement element)

Description copied from class: ICalPropertyScribe

Marshals a property's value to an XML element (xCal).

This method should be overridden by child classes that wish to support xCal. The default implementation of this method will append one child element to the property's XML element. The child element's name will be that of the property's data type (retrieved using the ICalPropertyScribe.dataType(T) method), and the child element's text content will be set to the property's marshalled plain-text value (retrieved using the ICalPropertyScribe.writeText(T) method).

Overrides:

_writeXml in class ICalPropertyScribe<T extends ListProperty<V>>

Parameters:

property - the property

element - the property's XML element

_parseXml

protected T _parseXml(XCalElement element,
          ICalParameters parameters,
          List<Warning> warnings)

Description copied from class: ICalPropertyScribe

Unmarshals a property from an XML document (xCal).

This method should be overridden by child classes that wish to support xCal. The default implementation of this method will find the first child element with the xCal namespace. The element's name will be used as the property's data type and its text content will be passed into the ICalPropertyScribe._parseText(java.lang.String, biweekly.ICalDataType, biweekly.parameter.ICalParameters, java.util.List<biweekly.Warning>) method. If no such child element is found, then the parent element's text content will be passed into ICalPropertyScribe._parseText(java.lang.String, biweekly.ICalDataType, biweekly.parameter.ICalParameters, java.util.List<biweekly.Warning>) and the data type will be null.

Overrides:

_parseXml in class ICalPropertyScribe<T extends ListProperty<V>>

Parameters:

element - the property's XML element

parameters - the parsed parameters. These parameters will be assigned to the property object once this method returns. Therefore, do not assign any parameters to the property object itself whilst inside of this method, or else they will be overwritten.

warnings - allows the programmer to alert the user to any note-worthy (but non-critical) issues that occurred during the unmarshalling process

Returns:

the unmarshalled property object

_writeJson

protected JCalValue _writeJson(T property)

Description copied from class: ICalPropertyScribe

Marshals a property's value to a JSON data stream (jCal).

This method should be overridden by child classes that wish to support jCal. The default implementation of this method will create a jCard property that has a single JSON string value (generated by the ICalPropertyScribe.writeText(T) method).

Overrides:

_writeJson in class ICalPropertyScribe<T extends ListProperty<V>>

Parameters:

property - the property

Returns:

the marshalled value

_parseJson

protected T _parseJson(JCalValue value,
           ICalDataType dataType,
           ICalParameters parameters,
           List<Warning> warnings)

Description copied from class: ICalPropertyScribe

/**

Unmarshals a property from a JSON data stream (jCal).

This method should be overridden by child classes that wish to support jCal. The default implementation of this method will convert the jCal property value to a string and pass it into the ICalPropertyScribe._parseText(java.lang.String, biweekly.ICalDataType, biweekly.parameter.ICalParameters, java.util.List<biweekly.Warning>) method.

The following paragraphs describe the way in which this method's default implementation converts a jCal value to a string:

If the jCal value consists of a single, non-array, non-object value, then the value is converted to a string. Special characters (backslashes, commas, and semicolons) are escaped in order to simulate what the value might look like in a plain-text iCalendar object.
["x-foo", {}, "text", "the;value"] --> "the\;value"
["x-foo", {}, "text", 2] --> "2"

If the jCal value consists of multiple, non-array, non-object values, then all the values are appended together in a single string, separated by commas. Special characters (backslashes, commas, and semicolons) are escaped for each value in order to prevent commas from being treated as delimiters, and to simulate what the value might look like in a plain-text iCalendar object.
["x-foo", {}, "text", "one", "two,three"] --> "one,two\,three"

If the jCal value is a single array, then this array is treated as a "structured value", and converted its plain-text representation. Special characters (backslashes, commas, and semicolons) are escaped for each value in order to prevent commas and semicolons from being treated as delimiters.
["x-foo", {}, "text", ["one", ["two", "three"], "four;five"]] --> "one;two,three;four\;five"

If the jCal value starts with a JSON object, then the object is converted to a format identical to the one used in the RRULE and EXRULE properties. Special characters (backslashes, commas, semicolons, and equal signs) are escaped for each value in order to preserve the syntax of the string value.
["x-foo", {}, "text", {"one": 1, "two": [2, 2.5]}] --> "ONE=1;TWO=2,2.5"

For all other cases, behavior is undefined.

Overrides:

_parseJson in class ICalPropertyScribe<T extends ListProperty<V>>

Parameters:

value - the property's JSON value

dataType - the data type

parameters - the parsed parameters. These parameters will be assigned to the property object once this method returns. Therefore, do not assign any parameters to the property object itself whilst inside of this method, or else they will be overwritten.

warnings - allows the programmer to alert the user to any note-worthy (but non-critical) issues that occurred during the unmarshalling process

Returns:

the unmarshalled property object
