Method Detail

checkVariable

protected boolean checkVariable(GUIVariable variable)

Description copied from class: AbstractConfigurationFilter

Determines whether a given variable should be shown inside the editor or not. Parents of variables which shall be shown should not be filtered. The AbstractConfigurationFilter ensures that.
This method must also ensure that nested elements of a shown variable are also displayed. Therefore, this method should also be written in a recursive manner to check nested elements of displayed variables. This should be done in the following way:
if(checkVariable(variable)) {
for(GUIVariable nestedVariable : variable.getNestedVars()) {
checkVariable(nestedVariable);
}
}

Specified by:

checkVariable in class AbstractConfigurationFilter

Parameters:

variable - The variable which should be tested whether it should be displayed inside the editor

Returns:

true if the variable should be displayed, false otherwise.
