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].

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.

deepEquals

boolean deepEquals(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.

deepHashCode

int deepHashCode()

Returns a hash code of this attribute selector that is compatible with deepEquals(Object).
