Method Detail

values

public static Axis[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Axis c : Axis.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Axis valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getName

public String getName()

The name used for the axis in motorplatform commands.

Returns:

The axis name string.

getPLCAxisNum

public int getPLCAxisNum()

The axis number used by the PLC code.

Returns:

The axis number.

fromName

public static Axis fromName(String name)

Find the Axis value having the given axis name.

Parameters:

name - The axis name to find.

Returns:

The corresponding Axis value.

Throws:

NoSuchElementException - if no matching value is found.

fromAxisNum

public static Axis fromAxisNum(int axnum)

Find the Axis value having the given PLC axis number.

Parameters:

axnum - The PLC axis number to find.

Returns:

The corresponding Axis value.

Throws:

NoSuchElementException - if no matching value is found.

isPlusXSide

public boolean isPlusXSide()

Tells whether the axis is for the +X blade set or the -X.

Returns:

true if it's the axis for the +X blade set.

getPlusXSide

public static Axis getPlusXSide()

Gets the axis that's controlling the blade set on the +X side.

Returns:

The axis.

getMinusXSide

public static Axis getMinusXSide()

Gets the axis that's controlling the blade set on the -X side.

Returns:

The axis.
