Returns:

The detected JavaTokens.J2SE_* value.

public static JavaType createArrayType(JavaProvider provider,
                                       JavaType component,
                                       int dimensions)

Returns:

                                                          JavaType[] arguments)

Deprecated. Please use the other createParameterizedType() method.

createTypeErasedClass

public static JavaType createTypeErasedClass(JavaType type)

createParameterizedType

public static JavaType createParameterizedType(JavaProvider provider,
                                               JavaType generic,
                                               JavaType[] arguments)

Parameters:

arguments - Collection of JavaType's.

Throws:

java.lang.IllegalArgumentException - if input type is not a generic type, if the input type is already bound, or if the arguments are not legal arguments to this generic type.

createDiamondParameterizedType

public static JavaType createDiamondParameterizedType(JavaProvider provider,
                                                      JavaType type)

Create a parameterized type (a type with type arguments) with an empty type argument list, useful for the 'new Type<>()' syntax

Parameters:

provider - The java provider

type - The type to use for the parameterized type

Throws:

java.lang.IllegalArgumentException - if input type is not a generic type, meaning it doesn't have typeParameters.

createParameterizedMethod

public static JavaMethod createParameterizedMethod(JavaProvider provider,
                                                   JavaMethod generic,
                                                   JavaType[] arguments)

Parameters:

arguments - Collection of JavaType's.

Throws:

java.lang.IllegalArgumentException - if input type is not a generic type.

createWildcardType

public static JavaType createWildcardType(byte bound,
                                          JavaType t,
                                          JavaProvider provider)

Creates a wildcard type. Note: "? extends java.lang.Object" and "?" are NOT equivalent as far as the jdk is concerned. Moreover, "? super java.lang.Object" is legal (but foolish).

 BOUND_NARROW:  "T"            T is returned, this is not a wildcard type.

 BOUND_EXTENDS: "? extends T"  If T is null, then this will be
                                 treated just like BOUND_NONE.

 BOUND_SUPER:   "? super T"    If T is null, an exception is thrown.

 BOUND_NONE:    "?"            T is ignored.
 

Parameters:

bound - Valid values are JavaConstants.BOUND_*.

t - The bounding type.

provider - A provider that can fetch java/lang/Object.

Returns:

The newly created WildcardType, except for BOUND_NARROW. If BOUND_NARROW is specified, then T is returned as is.

Throws:

java.lang.IllegalArgumentException - for an invalid bound parameter or an invalid type parameter.

matchMethod

public static boolean matchMethod(JavaMethod method,
                                  JavaType[] targetTypes)

isInheritedAnnotation

protected static boolean isInheritedAnnotation(JavaAnnotation annotation)

classProcessed

protected static boolean classProcessed(java.util.ArrayList processed,
                                        JavaType javaClass)

After this function, the input class will be added to the processed list. How the processed list is represented is up to the discretion of the implementer and the caller should not depend on knowing how the processed list works.

Parameters:

processed - An initially empty list for use with this function ONLY.

Returns:

True if the input class has already been iterated over.

asg_op

protected static byte asg_op(int token)
