接口 CompilablePropertyAccessor

所有超级接口:

org.springframework.asm.Opcodes, PropertyAccessor

所有已知实现类:

ReflectivePropertyAccessor.OptimalPropertyAccessor

public interface CompilablePropertyAccessor
extends PropertyAccessor, org.springframework.asm.Opcodes

A compilable property accessor is able to generate bytecode that represents the access operation, facilitating compilation to bytecode of expressions that use the accessor.

方法概要

限定符和类型	方法和说明
void	generateCode(String propertyName, org.springframework.asm.MethodVisitor mv, CodeFlow cf) Generate the bytecode the performs the access operation into the specified MethodVisitor using context information from the codeflow where necessary.
Class<?>	getPropertyType() Return the type of the accessed property - may only be known once an access has occurred.
boolean	isCompilable() Return true if this property accessor is currently suitable for compilation.

方法详细资料

isCompilable

boolean isCompilable()

Return true if this property accessor is currently suitable for compilation.

getPropertyType

Class<?> getPropertyType()

Return the type of the accessed property - may only be known once an access has occurred.

generateCode

void generateCode(String propertyName,
                  org.springframework.asm.MethodVisitor mv,
                  CodeFlow cf)

Generate the bytecode the performs the access operation into the specified MethodVisitor using context information from the codeflow where necessary.

参数:

propertyName - the name of the property

mv - the Asm method visitor into which code should be generated

cf - the current state of the expression compiler
