Method Details

generateCode

@Nullable org.springframework.javapoet.CodeBlock generateCode(org.springframework.javapoet.TypeName argumentType)

Generate the code for the given argument type. If this type is not supported, return null.

Parameters:

argumentType - the argument type

Returns:

the code for this argument, or null

none

static MethodReference.ArgumentCodeGenerator none()

Factory method that returns an MethodReference.ArgumentCodeGenerator that always returns null.

Returns:

a new MethodReference.ArgumentCodeGenerator instance

of

static MethodReference.ArgumentCodeGenerator of(Class<?> argumentType,
 String argumentCode)

Factory method that can be used to create an MethodReference.ArgumentCodeGenerator that support only the given argument type.

Parameters:

argumentType - the argument type

argumentCode - the code for an argument of that type

Returns:

a new MethodReference.ArgumentCodeGenerator instance

from

static MethodReference.ArgumentCodeGenerator from(Function<org.springframework.javapoet.TypeName, @Nullable org.springframework.javapoet.CodeBlock> function)

Factory method that creates a new MethodReference.ArgumentCodeGenerator from a lambda friendly function. The given function is provided with the argument type and must provide the code to use or null if the type is not supported.

Parameters:

function - the resolver function

Returns:

a new MethodReference.ArgumentCodeGenerator instance backed by the function

and

default MethodReference.ArgumentCodeGenerator and(Class<?> argumentType,
 String argumentCode)

Create a new composed MethodReference.ArgumentCodeGenerator by combining this generator with supporting the given argument type.

Parameters:

argumentType - the argument type

argumentCode - the code for an argument of that type

Returns:

a new composite MethodReference.ArgumentCodeGenerator instance

and

default MethodReference.ArgumentCodeGenerator and(MethodReference.ArgumentCodeGenerator argumentCodeGenerator)

Create a new composed MethodReference.ArgumentCodeGenerator by combining this generator with the given generator.

Parameters:

argumentCodeGenerator - the argument generator to add

Returns:

a new composite MethodReference.ArgumentCodeGenerator instance
