Method Detail

getAxis

public static int getAxis(java.lang.String axisname)

Parameters:

axisname - name of the axis. should look like "axis::".
If axisname is null or not a valid axis name, getAxis returns INVALID.
If axisname is empty string, result is CHILD axis.
If axisname is "@", result is ATTRIBUTE axis.
TODO: implement both "axis::" and "axis" argument support.

Returns:

Returns integer axis code for a given axisname.

getAxisName

public static java.lang.String getAxisName(int axis)

Parameters:

axis - integer code of the axis.

Returns:

Returns the string representation a given axis.

String representations are always returned in full non-abbreviated form, for example Axis.getAxisName(Axis.CHILD) returns "child".
