C# Class SharpVectors.Dom.Css.CssPrimitiveValue

The CSSPrimitiveValue interface represents a single CSS value.

This interface may be used to determine the value of a specific style property currently set in a block or to set a specific style property explicitly within the block. An instance of this interface might be obtained from the getPropertyCSSValue method of the CSSStyleDeclaration interface. A CSSPrimitiveValue object only occurs in a context of a CSS property.

Conversions are allowed between absolute values (from millimeters to centimeters, from degrees to radians, and so on) but not between relative values. (For example, a pixel value cannot be converted to a centimeter value.) Percentage values can't be converted since they are relative to the parent value (or another property value). There is one exception for color percentage values: since a color percentage value is relative to the range 0-255, a color percentage value can be converted to a number; (see also the RGBColor interface).

Inheritance: CssValue, ICssPrimitiveValue

Public Methods

Method	Description
GetAbsoluteValue ( string propertyName, XmlElement elm ) : CssValue
GetCounterValue ( ) : SharpVectors.Dom.Css.ICounter	This method is used to get the Counter value. If this CSS value doesn't contain a counter value, a DOMException is raised. Modification to the corresponding style property can be achieved using the Counter interface
GetFloatValue ( CssPrimitiveType unitType ) : double	This method is used to get a float value in a specified unit. If this CSS value doesn't contain a float value or can't be converted into the specified unit, a DOMException is raised
GetRectValue ( ) : SharpVectors.Dom.Css.IRect	This method is used to get the Rect value. If this CSS value doesn't contain a rect value, a DOMException is raised. Modification to the corresponding style property can be achieved using the Rect interface.
GetRgbColorValue ( ) : SharpVectors.Dom.Css.IRgbColor	This method is used to get the RGB color. If this CSS value doesn't contain a RGB color value, a DOMException is raised. Modification to the corresponding style property can be achieved using the RGBColor interface.
GetStringValue ( ) : string	This method is used to get the string value. If the CSS value doesn't contain a string value, a DOMException is raised. Note: Some properties (like 'font-family' or 'voice-family') convert a whitespace separated list of idents to a string.
SetFloatValue ( CssPrimitiveType unitType, double floatValue ) : void	A method to set the float value with a specified unit. If the property attached with this value can not accept the specified unit or the float value, the value will be unchanged and a DOMException will be raised.
SetStringValue ( CssPrimitiveType stringType, string stringValue ) : void	A method to set the string value with the specified unit. If the property attached to this value can't accept the specified unit or the string value, the value will be unchanged and a DOMException will be raised.

GetAbsoluteValue() public method

public GetAbsoluteValue ( string propertyName, XmlElement elm ) : CssValue
propertyName	string
elm	System.Xml.XmlElement
return	CssValue

GetCounterValue() public method

This method is used to get the Counter value. If this CSS value doesn't contain a counter value, a DOMException is raised. Modification to the corresponding style property can be achieved using the Counter interface

INVALID_ACCESS_ERR: Raised if the CSS value doesn't contain a Counter value (e.g. this is not CSS_COUNTER).

public GetCounterValue ( ) : SharpVectors.Dom.Css.ICounter
return	SharpVectors.Dom.Css.ICounter

GetFloatValue() public method

This method is used to get a float value in a specified unit. If this CSS value doesn't contain a float value or can't be converted into the specified unit, a DOMException is raised

INVALID_ACCESS_ERR: Raised if the CSS value doesn't contain a float value.

public GetFloatValue ( CssPrimitiveType unitType ) : double
unitType	CssPrimitiveType	A unit code to get the float value. The unit code can only be a float unit type (i.e. CSS_NUMBER, CSS_PERCENTAGE, CSS_EMS, CSS_EXS, CSS_PX, CSS_CM, CSS_MM, CSS_IN, CSS_PT, CSS_PC, CSS_DEG, CSS_RAD, CSS_GRAD, CSS_MS, CSS_S, CSS_HZ, CSS_KHZ, CSS_DIMENSION).
return	double

GetRectValue() public method

This method is used to get the Rect value. If this CSS value doesn't contain a rect value, a DOMException is raised. Modification to the corresponding style property can be achieved using the Rect interface.

INVALID_ACCESS_ERR: Raised if the CSS value doesn't contain a rect value.

public GetRectValue ( ) : SharpVectors.Dom.Css.IRect
return	SharpVectors.Dom.Css.IRect

GetRgbColorValue() public method

This method is used to get the RGB color. If this CSS value doesn't contain a RGB color value, a DOMException is raised. Modification to the corresponding style property can be achieved using the RGBColor interface.

INVALID_ACCESS_ERR: Raised if the CSS value doesn't contain a rgb value.

public GetRgbColorValue ( ) : SharpVectors.Dom.Css.IRgbColor
return	SharpVectors.Dom.Css.IRgbColor

GetStringValue() public method

This method is used to get the string value. If the CSS value doesn't contain a string value, a DOMException is raised. Note: Some properties (like 'font-family' or 'voice-family') convert a whitespace separated list of idents to a string.

INVALID_ACCESS_ERR: Raised if the CSS value doesn't contain a string value.

public GetStringValue ( ) : string
return	string

SetFloatValue() public method

A method to set the float value with a specified unit. If the property attached with this value can not accept the specified unit or the float value, the value will be unchanged and a DOMException will be raised.

INVALID_ACCESS_ERR: Raised if the CSS value doesn't contain a float value. NO_MODIFICATION_ALLOWED_ERR: Raised if this property is readonly.

public SetFloatValue ( CssPrimitiveType unitType, double floatValue ) : void
unitType	CssPrimitiveType	A unit code as defined above. The unit code can only be a float unit type (i.e. CSS_NUMBER, CSS_PERCENTAGE, CSS_EMS, CSS_EXS, CSS_PX, CSS_CM, CSS_MM, CSS_IN, CSS_PT, CSS_PC, CSS_DEG, CSS_RAD, CSS_GRAD, CSS_MS, CSS_S, CSS_HZ, CSS_KHZ, CSS_DIMENSION).
