NameSummary[disableGC](../../com.phoenix_int.ModelCenter.util/-p-h-x-c-o-m-object/disable-g-c.md)public [disableGC](../../com.phoenix_int.ModelCenter.util/-p-h-x-c-o-m-object/disable-g-c.md)(gc: [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html))  
If true, prevents releaseObjects from doing anything.[getEquation](get-equation.md)public [getEquation](get-equation.md)(): [String](https://docs.oracle.com/javase/8/docs/api/java/lang/String.html)  
if the variable is a custom variable, this function returns the equation used to compute the value for the variable.[getFullName](get-full-name.md)public [getFullName](get-full-name.md)(): [String](https://docs.oracle.com/javase/8/docs/api/java/lang/String.html)  
gets the full name of the variable, e.g.[getName](get-name.md)public [getName](get-name.md)(): [String](https://docs.oracle.com/javase/8/docs/api/java/lang/String.html)  
gets the name of the variable, e.g.[getState](get-state.md)public [getState](get-state.md)(): [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)  
gets the state of the variable, either PHXVariableDescription.INPUT or PHXVariableDescription.OUTPUT.[getType](get-type.md)public [getType](get-type.md)(): [String](https://docs.oracle.com/javase/8/docs/api/java/lang/String.html)  
gets the type of the variable, e.g.[getUnits](get-units.md)public [getUnits](get-units.md)(): [String](https://docs.oracle.com/javase/8/docs/api/java/lang/String.html)  
gets the units of the variable, if any[isCustom](is-custom.md)public [isCustom](is-custom.md)(): [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)  
indicates if the variable is a custom variable, i.e.[isNumeric](is-numeric.md)public [isNumeric](is-numeric.md)(): [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)  
indicates if the variable is numeric or not[release](../../com.phoenix_int.ModelCenter.util/-p-h-x-c-o-m-object/release.md)public [release](../../com.phoenix_int.ModelCenter.util/-p-h-x-c-o-m-object/release.md)()  
Releases the COM reference to ModelCenter for this object.[releaseObjects](../../com.phoenix_int.ModelCenter.util/-p-h-x-c-o-m-object/release-objects.md)public [releaseObjects](../../com.phoenix_int.ModelCenter.util/-p-h-x-c-o-m-object/release-objects.md)()  
This function attempts to release any COM resources left behind from objects which have been finalized but release() was never called on them.[setReferenceDebugMode](../../com.phoenix_int.ModelCenter.util/-p-h-x-c-o-m-object/set-reference-debug-mode.md)public [setReferenceDebugMode](../../com.phoenix_int.ModelCenter.util/-p-h-x-c-o-m-object/set-reference-debug-mode.md)(on: [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html))  
When set to true, the system will keep a list of active COM objects that are allocated but not yet released since this method was invoked.
