构造器详细资料

BytecodeCompiler

protected BytecodeCompiler(@Nullable
 ClassLoader classloader)

方法详细资料

compile

public <T> Class<T> compile(String className,
 byte[] classFile)

类型参数:

T - class type

参数:

className - class full name like 'cn.taketoday.xxx'

classFile - class byte-code data

返回:

Class

compile

public <T> Class<T> compile(byte[] classFile)

类型参数:

T - class type

参数:

classFile - class byte-code data

返回:

Class

loadClass

protected <T> Class<T> loadClass(String name,
 byte[] classFile)

Load a class. Makes sure the classloaders aren't used too much because they anchor compiled classes in memory and prevent GC. If you have expressions continually recompiling over time then by replacing the classloader periodically at least some of the older variants can be garbage collected.

参数:

name - the name of the class

classFile - the bytecode for the class

返回:

the Class object for the compiled expression

getCompiler

public static BytecodeCompiler getCompiler(@Nullable
 ClassLoader classLoader)

Factory method for compiler instances. The returned BytecodeCompiler will attach a class loader as the child of the given class loader and this child will be used to load compiled expressions.

参数:

classLoader - the ClassLoader to use as the basis for compilation

返回:

a corresponding BytecodeCompiler instance
