public Interface CompilablePropertyAccessor

Known Direct Implementers: org.springframework.expression.spel.support.ReflectivePropertyAccessor.OptimalPropertyAccessor
Imports: org.springframework.asm.MethodVisitor, .Opcodes, org.springframework.expression.PropertyAccessor

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

Method Summary

Modifier and Type	Method and Description
public void	generateCode(String the name of the property propertyName, MethodVisitor the ASM method visitor into which code should be generated methodVisitor, CodeFlow the current state of the expression compiler codeFlow) Generate the bytecode the performs the access operation into the specified `MethodVisitor` using context information from the `CodeFlow` where necessary.
public Class<?>	getPropertyType() Return the type of the accessed property - may only be known once an access has occurred.
public boolean	isCompilable() Return `true` if this property accessor is currently suitable for compilation.
