Class DefaultPropertyMap<T>

java.lang.Object
ghidra.program.model.util.DefaultPropertyMap<T>
Type Parameters:
T - property value type
All Implemented Interfaces:
PropertyMap<T>
Direct Known Subclasses:
DefaultIntPropertyMap
public abstract class DefaultPropertyMap<T> extends Object implements PropertyMap<T>
PropertyMap is used to store values for a fixed property at address locations given as longs. The values for the property must be homogeneous, i.e. all have the same type, and are determined by which subclass of PropertyMap is instantiated. For any long the property manager can be used to tell if the property exists there and what its value is. It also maintains information that allows it to efficiently search for the next and previous occurrence of the property relative to a given address. The subclass provides the createPage() method that dictates the type of PropertyPage that will be managed.
