Class GenerateMethodReader

java.lang.Object

net.openhft.chronicle.wire.GenerateMethodReader

public class GenerateMethodReader
extends Object

Responsible for code generation and runtime compilation of custom MethodReaders. The class dynamically generates Java source code based on the provided configurations and compiles it on the fly. Generated readers extend AbstractGeneratedMethodReader for faster dispatch than reflection and are used internally by VanillaMethodReaderBuilder.

Constructor Detail

GenerateMethodReader

public GenerateMethodReader(WireType wireType,
                            net.openhft.chronicle.bytes.MethodReaderInterceptorReturns interceptor,
                            Boolean multipleNonMarshallableParamTypes,
                            Object[] metaDataHandler,
                            Object... instances)

Constructs a new instance of GenerateMethodReader. Initializes the required configurations, metadata handlers, and instances which are essential for code generation.

Parameters:

wireType - target wire format

interceptor - optional interceptor for return values

multipleNonMarshallableParamTypes - if Boolean#TRUE support multiple concrete parameter types, Boolean#FALSE forces a single type, null chooses automatically

metaDataHandler - array of meta-data handlers, may be null

instances - handlers that dictate the structure of the generated MethodReader

Method Detail

createClass

public Class<?> createClass()

Generates (if not already done) and compiles the source code of a custom MethodReader at runtime. It uses the configurations and instances provided during initialization. If there are issues during compilation, it provides detailed error messages for easier debugging.

Returns:

A new class representing the custom MethodReader

packageName

public String packageName()

Retrieves the package name for the generated class. The package name is determined based on the class name of the first instance.

Returns:

The package name of the generated class.

generatedClassName

public String generatedClassName()

Gets the simple name of the generated class.

Returns:

The simple name of the generated class.
