MethodReference
public MethodReference(boolean nullSafe, String methodName, int pos, SpelNodeImpl... arguments)
方法详细资料
getValueRef
protected ValueRef getValueRef(ExpressionState state) throws EvaluationException
- 覆盖:
getValueRef在类中SpelNodeImpl- 抛出:
EvaluationException
getValueInternal
public TypedValue getValueInternal(ExpressionState state) throws EvaluationException
- 指定者:
getValueInternal在类中SpelNodeImpl- 抛出:
EvaluationException
toStringAST
public String toStringAST()
- 返回:
- the string form of this AST node
isCompilable
public boolean isCompilable()
A method reference is compilable if it has been resolved to a reflectively accessible method and the child nodes (arguments to the method) are also compilable.- 覆盖:
isCompilable在类中SpelNodeImpl- 返回:
trueif this node can be compiled to bytecode
generateCode
public void generateCode(MethodVisitor mv, CodeFlow cf)
从类复制的说明:SpelNodeImplGenerate the bytecode for this node into the supplied visitor. Context info about the current expression being compiled is available in the codeflow object. For example it will include information about the type of the object currently on the stack.- 覆盖:
generateCode在类中SpelNodeImpl- 参数:
mv- the ASM MethodVisitor into which code should be generatedcf- a context object with info about what is on the stack
