Method Detail

getDouble

public double getDouble(java.lang.String var)

Gets the double keyed to this value. String values are converted to double using a math expression parser.

Specified by:

getDouble in interface Control

Overrides:

getDouble in class GroupControl

Parameters:

var - String

Returns:

double

getObject

public java.lang.Object getObject(java.lang.String var)

Gets the object keyed to the variable.

Specified by:

getObject in interface Control

Overrides:

getObject in class GroupControl

Parameters:

var - String

Returns:

Object

getInt

public int getInt(java.lang.String var)

Gets the integer keyed to this value. String values are converted to int using a math expression parser.

Specified by:

getInt in interface Control

Overrides:

getInt in class GroupControl

Parameters:

var - String

Returns:

double
