Modifier and Type	Method and Description
static <T> T	castGenericType(java.lang.Object obj, java.lang.Class<T> valType) This attempts to cast a value stored as an object to a generic type.
static boolean	isAnyType(java.lang.Class<?> clazz, java.lang.Class<?>... classTypes) Checks if the input class is assignable from any of the input class types
static boolean	isInstanceAnyType(java.lang.Object obj, java.lang.Class<?>... types) Checks if the input value extends any of the input class types

Method Detail

castGenericType

public static <T> T castGenericType(@Nullable
                                    java.lang.Object obj,
                                    java.lang.Class<T> valType)

This attempts to cast a value stored as an object to a generic type. If the object is a primitive type, a stronger cast is performed by getting the string value and reparsing it

isAnyType

public static boolean isAnyType(java.lang.Class<?> clazz,
                                java.lang.Class<?>... classTypes)

Checks if the input class is assignable from any of the input class types

isInstanceAnyType

public static boolean isInstanceAnyType(java.lang.Object obj,
                                        java.lang.Class<?>... types)

Checks if the input value extends any of the input class types

isListAnyType

public static boolean isListAnyType(java.util.List<?> list,
                                    java.lang.Class<?>... classTypes)

The list type can't be checked if it's empty, so it has to return false if that is the case.

isPrimitive

public static boolean isPrimitive(java.lang.Class<?> clazz)

Checks if the class is a primitive type. All Number extensions and Strings are treated as primitive for parsing purposes.

isPrimitiveInstance

public static boolean isPrimitiveInstance(java.lang.Object obj)

Checks if the object is a primitive type. All Number extensions and Strings are treated as primitive for parsing purposes.

matches

public static boolean matches(@Nullable
                              java.lang.Object value,
                              @Nullable
                              java.lang.Object other)

Runs non-strict equality rules. If both inputs are null, they are considered matching. If both elements are equal, they are considered matching. If the value is a string, and it equals the string value of the other, they are considered matching. If the value is a number, and it equals the numerical value of the other, they are considered matching. If the value is a boolean, it will match parsed booleans from strings or numbers (0=false,1=true) If the value is an array, iterable, or iterator further matching rules will be applied. If the type is unknown, the toString values of both inputs will be checked for equality.

numberAdd

public static java.lang.Number numberAdd(java.lang.Number n1,
                                         java.lang.Number n2)

numberDiv

public static java.lang.Number numberDiv(java.lang.Number n1,
                                         java.lang.Number n2)

numberMatches

public static boolean numberMatches(java.lang.Number number,
                                    java.lang.Object other)

numberMul

public static java.lang.Number numberMul(java.lang.Number n1,
                                         java.lang.Number n2)

numberSub

public static java.lang.Number numberSub(java.lang.Number n1,
                                         java.lang.Number n2)

parseGenericFromTag

public static java.lang.Object parseGenericFromTag(CompoundTagAPI<?> tag)

Assumes the value is stored as a string

parseGenericType

public static java.lang.Object parseGenericType(java.lang.String unparsed,
                                                java.lang.Class<?> valType)

This only handles primitive types for the most part, so it may be better to just do whatever you want manually

parseNumber

public static <N extends java.lang.Number> N parseNumber(java.lang.String unparsed,
                                                         java.lang.Class<?> valType)

Luckily the parse methods for each number type all follow the same format, with a minor exception for parseInt. Does not handle NumberFormatException occurances.

parseNumber

public static <N extends java.lang.Number> N parseNumber(java.lang.String unparsed,
                                                         N defaultValue)

parsePrimitive

public static java.lang.Object parsePrimitive(java.lang.String unparsed,
                                              java.lang.Class<?> valType)

writeGenericToTag

public static void writeGenericToTag(CompoundTagAPI<?> tag,
                                     java.lang.Object obj)
