Interface IlvCSSAttributeSelector

public interface IlvCSSAttributeSelector

This interface defines the read only access to the attribute selectors of a simple selector of a CSS rule. Each CSS rule consists of a sequence of simple selectors that define how the rule matches the objects, and the declarations the define how to set the properties of the matches objects. For instance, the CSS rule

 node.activity[workload==5]:touched {
   x: 100;
   y: 200;
 }
 

contains the simple selector node.activity[workload==5]:touched which has the attribute selector [workload==5].

Since:

JViews 7.5

Field Summary

static int	DIFFERENT_NUM Tests that the attribute at the matching object is unequal to the value.
static int	DIFFERENT_STRING Tests that the attribute at the matching object is unequal to the value.
static int	EQUAL Tests that the attribute at the matching object is equal to the value.
static int	EXACT Tests that the attribute at the matching object is equal to the value.
static int	GREATER Tests that the attribute at the matching object is greater than the value.
static int	GREATER_EQUAL Tests that the attribute at the matching object is greater or equal to the value.
static int	LESS Tests that the attribute at the matching object is less than the value.
static int	LESS_EQUAL Tests that the attribute at the matching object is less or equal to the value.
static int	NONE Tests whether the attribute exists at the matching object and is not null.
static int	SUBSTRING Tests that the attribute at the matching object is a list of space-separated words, one of which is exactly equal to the value.

Method Summary

String	getAttributeName() Returns the attribute name of the attribute selector.
int	getComparator() Returns the comparator of the attribute selector.

Method Detail

getAttributeName

String getAttributeName()

Returns the attribute name of the attribute selector.

Returns:

The left hand part of the attribute selector.

getValue

String getValue()

Returns the comparison value of the attribute selector as String. The comparison value is ignored for the comparator NONE.

Returns:

The right hand part of the attribute selector.

getComparator

int getComparator()

Returns the comparator of the attribute selector. Possible values are NONE, EXACT, SUBSTRING, GREATER, GREATER_EQUAL, LESS, LESS_EQUAL, EQUAL, DIFFERENT_NUM, DIFFERENT_STRING.

printCSS

void printCSS(PrintWriter out,
              int indent)

Prints the attribute selector using CSS syntax.

Parameters:

out - The output print writer.

indent - The indentation level.

isIdentical

boolean isIdentical(Object obj)

Returns true if this attribute selector is considered logically identical to the input object. It compares the attribute name, value and the comparator.

Parameters:

obj - The object to compare with.
