Class StyleContext.SmallAttributeSet

All Implemented Interfaces:
AttributeSet
Enclosing class:
StyleContext
public class StyleContext.SmallAttributeSet
extends Object
implements AttributeSet

This class holds a small number of attributes in an array. The storage format is key, value, key, value, etc. The size of the set is the length of the array divided by two. By default, this is the class that will be used to store attributes when held in the compact sharable form.

equals

public boolean equals(Object obj)

Compares this object to the specified object. The result is true if the object is an equivalent set of attributes.

Overrides:
equals in class Object
