routines to treat the array like a stack

Seeks to an relative offset in the stream. If this cannot be done, returns false. * If an attempt is made to move to a position outside the stre

Returns true if either widht or height are <= 0 */

* Returns true if a valid object has been initialized in the SkTLazy, * false otherwise. */

* Number of elements in the array. */

It is essential we return by value rather than by const&. fVal may change at any time.

Return a SkColor value from 8 bit component values */

Return the next pseudo random number as an unsigned 32bit value. */

* Return a*b/255, rounding any fractional bits. * Only valid if a and b are unsigned and <= 32767. */

Return the array of T elements. Will be NULL if count == 0 */

* Returns the object. This version should only be called when the caller * knows that the object has been initialized. */

Return the reference count. Use only for debugging. */

* Adopt the new bare pointer, and call unref() on any previously held object (if not null). * No call to ref() will be made. */

4 char null terminated string consisting only of chars 'r', 'g', 'b', 'a'. */

* Pack 4 components (RGBA) into a GrColor int */

In the following move and copy methods, 'dst' is assumed to be uninitialized raw storage. * In the following move methods, 'src' is destroyed le

Returns constructed SkIRect set to (0, 0, size.width(), size.height()). Does not validate input; size.width() or size.height() may be negative

Asserts if SkPath data is inconsistent. Debugging check intended for internal use only. */

* Returns the array of points. */

Destroys previous objects in the array and default constructs count number of objects */

Returns x-axis value of SkIPoint. @return fX */

Returns y-axis value of SkIPoint. @return fY */

Returns true if a intersects b. Returns false if either a or b is empty, or do not intersect. @param a SkIRect to intersect

* Helper to compare an array of scalars. */
