# Interface: com.pnfsoftware.jeb.core.units.code.asm.type.IPrototypeItem A native prototype. A prototype item contains return\- and parameter types, calling convention, as well as other calling convention attributes. Note: a reference\-item to a prototype\-item is a function\-pointer type. ## Method: getCallingConvention - return type: `com.pnfsoftware.jeb.core.units.code.asm.type.ICallingConvention` Description: Retrieve the optional calling convention associated with the prototype. return: calling convention, or null ## Method: getCountOfParameters - return type: `int` Description: Get the number of parameters. return: parameter count ## Method: getCountOfReturns - return type: `int` Description: Get the number of return values. return: return value count ## Method: getParameterNames - return type: `java.util.List` Description: Get optional parameter names. return: optional parameter names, if they were provided with the prototype ## Method: getParameterTypes - return type: `java.util.List` Description: Get parameter types. return: parameter types ## Method: getPrototypeAttributes - return type: `java.util.Collection` Description: Retrieve the prototype attributes. return: prototype attributes, never null ## Method: getReturnType - return type: `com.pnfsoftware.jeb.core.units.code.asm.type.INativeType` Description: Get the primary return type. return: return type, or null ## Method: getReturnTypes - return type: `java.util.List` Description: Get all return types. return: return types ## Method: getRoutineName - return type: `java.lang.String` Description: Get the optional routine name. return: optional routine name, if it was provided with the prototype ## Method: isNoReturn - return type: `boolean` Description: Convenience method. return: true if the prototype is non\-returning
