方法详细资料

factoryMethod

public static void factoryMethod(ClassEmitter ce,
 MethodSignature sig)

nullConstructor

public static void nullConstructor(ClassEmitter ce)

processArray

public static void processArray(GeneratorAdapter e,
 Type type,
 ProcessArrayCallback callback)

Process an array on the stack. Assumes the top item on the stack is an array of the specified type. For each element in the array, puts the element on the stack and triggers the callback.

参数:

type - the type of the array (type.isArray() must be true)

callback - the callback triggered for each element

processArrays

public static void processArrays(CodeEmitter e,
 Type type,
 ProcessArrayCallback callback)

Process two arrays on the stack in parallel. Assumes the top two items on the stack are arrays of the specified class. The arrays must be the same length. For each pair of elements in the arrays, puts the pair on the stack and triggers the callback.

参数:

type - the type of the arrays (type.isArray() must be true)

callback - the callback triggered for each pair of elements

stringSwitch

public static void stringSwitch(CodeEmitter e,
 String[] strings,
 int switchStyle,
 ObjectSwitchCallback callback)

stringSwitchTrie

private static void stringSwitchTrie(CodeEmitter e,
 String[] strings,
 ObjectSwitchCallback callback)

stringSwitchHelper

private static void stringSwitchHelper(CodeEmitter e,
 List strings,
 ObjectSwitchCallback callback,
 Label def,
 Label end,
 int index)

getSwitchKeys

protected static <T> int[] getSwitchKeys(Map<Integer,List<T>> buckets)

pushObject

public static void pushObject(CodeEmitter e,
 Object obj)

hashCode

@Deprecated
public static void hashCode(GeneratorAdapter e,
 Type type,
 int multiplier,
 Customizer customizer)

已过时。

use hashCode(GeneratorAdapter, Type, int, CustomizerRegistry) instead

hashCode

public static void hashCode(GeneratorAdapter e,
 Type type,
 int multiplier,
 CustomizerRegistry registry)

 Type type)

hashLong

private static void hashLong(GeneratorAdapter e)

notEquals

public static void notEquals(CodeEmitter e,
 Type type,
 Label notEquals,
 CustomizerRegistry registry)

Branches to the specified label if the top two items on the stack are not equal. The items must both be of the specified class. Equality is determined by comparing primitive values directly and by invoking the equals method for Objects. Arrays are recursively processed in the same manner.

notEqualsHelper

private static void notEqualsHelper(CodeEmitter e,
 Type type,
 Label notEquals,
 CustomizerRegistry registry,
 ProcessArrayCallback callback)

nullcmp

private static void nullcmp(CodeEmitter e,
 Label oneNull,
 Label bothNull)

If both objects on the top of the stack are non-null, does nothing. If one is null, or both are null, both are popped off and execution branches to the respective label.

参数:

oneNull - label to branch to if only one of the objects is null

bothNull - label to branch to if both of the objects are null
