Constructor Detail

MemberTypeAdditions

public MemberTypeAdditions(ClassOrInterfaceTypeDetailsBuilder builder,
                           String methodName,
                           String methodCall,
                           boolean isStatic,
                           List<MethodParameter> methodParameters)

Constructor that takes a pre-built method call.

Parameters:

builder - stores any changes the caller should make in order to make the given method call, e.g. the field that is the method target; can be null if the caller requires no changes other than the given method call

methodName - the bare name of the method being invoked (required)

methodCall - a valid Java snippet that calls the method, including any required target and parameters, for example "foo.bar(baz)" (required)

isStatic - whether the invoked method is static

methodParameters - the parameters taken by the invoked method (can be null)

Method Detail

getInstance

public static MemberTypeAdditions getInstance(ClassOrInterfaceTypeDetailsBuilder builder,
                                              String targetName,
                                              String methodName,
                                              boolean isStatic,
                                              List<MethodParameter> parameters)

Factory method that builds the method call from the given target, method, and list of parameter names.

Parameters:

builder - stores any changes the caller should make in order to make the given method call, e.g. the field that is the method target (required)

targetName - the name of the object or class on which the method is being invoked (if not blank, must be a valid Java name)

methodName - the name of the method being invoked (must be a valid Java name)

isStatic - whether the invoked method is static

parameterNames - the names of any parameters passed to the method (required)

getInstance

public static MemberTypeAdditions getInstance(ClassOrInterfaceTypeDetailsBuilder builder,
                                              String targetName,
                                              String methodName,
                                              boolean isStatic,
                                              MethodParameter... parameters)

Factory method that builds the method call from the given target, method, and array of parameter names.

Parameters:

builder - stores any changes the caller should make in order to make the given method call, e.g. the field that is the method target (required)

targetName - the name of the object or class on which the method is being invoked (if not blank, must be a valid Java name)

methodName - the name of the method being invoked (must be a valid Java name)

isStatic - whether the invoked method is static

parameterNames - the names of any parameters passed to the method (required)
