public interface: CSSPrimitiveValue [javadoc | source]

All Implemented Interfaces:
    CSSValue

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).

See also the Document Object Model (DOM) Level 2 Style Specification.

Method from org.w3c.dom.css.CSSPrimitiveValue Summary:
getCounterValue,   getFloatValue,   getPrimitiveType,   getRGBColorValue,   getRectValue,   getStringValue,   setFloatValue,   setStringValue
Method from org.w3c.dom.css.CSSPrimitiveValue Detail:
 public Counter getCounterValue() throws DOMException
    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.
 public float getFloatValue(short unitType) throws DOMException
    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.
 public short getPrimitiveType()
    The type of the value as defined by the constants specified above.
 public RGBColor getRGBColorValue() throws DOMException
    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.
 public Rect getRectValue() throws DOMException
    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.
 public String getStringValue() throws DOMException
    This method is used to get the string value. If the CSS value doesn't 
contain a string value, a DOMException is raised.  Some 
properties (like 'font-family' or 'voice-family') convert a 
whitespace separated list of idents to a string.
 public  void setFloatValue(short unitType,
    float floatValue) throws DOMException
    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.
 public  void setStringValue(short stringType,
    String stringValue) throws DOMException
    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.
