All plugin code accessing the native units and units relying on native units should use those locks to perform operations safely in a concurrent environment. return: model lock ## Method: getNextItem - parameter: `address`, type: `long` - return type: `com.pnfsoftware.jeb.core.units.code.asm.items.INativeContinuousItem` Description: Retrieve the closest item whose address is strictly greater than the provided address. parameter: address: address to query return: the next item or null ## Method: getNextItem - parameter: `item`, type: `com.pnfsoftware.jeb.core.units.code.asm.items.INativeContinuousItem` - return type: `com.pnfsoftware.jeb.core.units.code.asm.items.INativeContinuousItem` Description: Retrieve the closest item after the given one.. parameter: item: current item return: the next item or null ## Method: getPreviousItem - parameter: `item`, type: `com.pnfsoftware.jeb.core.units.code.asm.items.INativeContinuousItem` - return type: `com.pnfsoftware.jeb.core.units.code.asm.items.INativeContinuousItem` Description: Retrieve the closest before the given one.. parameter: item: current item return: the previous item or null ## Method: getPreviousItem - parameter: `address`, type: `long` - return type: `com.pnfsoftware.jeb.core.units.code.asm.items.INativeContinuousItem` Description: Retrieve the closest item whose address is strictly less than the provided address. parameter: address: address to query return: the previous item or null ## Method: getView - return type: `java.util.SortedMap` Description: Get a full view of the current model. Same as [getView\(null, null\)](#getView(Long, Long)). return: an unmodifiable view of the model containing the native items ## Method: getView - parameter: `fromAddress`, type: `java.lang.Long` - parameter: `toAddress`, type: `java.lang.Long` - return type: `java.util.SortedMap` Description: Get a copy view of the current model. parameter: fromAddress: optional start address parameter: toAddress: optional end address return: an unmodifiable view of the model containing the native items ## Method: isEmpty - return type: `boolean` Description: Determine if the model is empty. return: true if the model has no item ## Method: isEmptyRange - parameter: `address`, type: `long` - parameter: `size`, type: `int` - return type: `boolean` Description: Determine if a provided range is free \(ie, contains no item or overlapping item\). parameter: address: start address parameter: size: range size return: true if the range contains no item ## Method: notifyListenersOfModelChange - parameter: `eventType`, type: `com.pnfsoftware.jeb.core.units.code.asm.analyzer.MemoryModelEventType` - parameter: `eventDetails`, type: `java.lang.Object` Description: Issue a notification of model change to all listeners. parameter: eventType: event type parameter: eventDetails: event details ## Method: removeListener - parameter: `listener`, type: `com.pnfsoftware.jeb.core.units.code.asm.analyzer.IMemoryModelListener` Description: Unregister a listener. parameter: listener: listener to remove ## Method: size - return type: `int` Description: Provide the number of elements in the model. return: number of items
