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.

attributes
- the attributes
SmallAttributeSet
public SmallAttributeSet(AttributeSet attrs)
Constructs a SmallAttributeSet.
- Parameters:
-
attrs
- the attributes
Method Detail
toString
public String toString()
Returns a string showing the key/value pairs.
hashCode
public int hashCode()
Returns a hashcode for this set of attributes.

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 classObject
- Parameters:
