Method Detail
getValueRef
protected ValueRef getValueRef(ExpressionState state) throws EvaluationException
- Overrides:
getValueRefin classSpelNodeImpl- Throws:
EvaluationException
getValueInternal
public TypedValue getValueInternal(ExpressionState state) throws EvaluationException
- Specified by:
getValueInternalin classSpelNodeImpl- Throws:
EvaluationException
toStringAST
public String toStringAST()
Description copied from interface:SpelNodeReturn the string form the this AST node.- Returns:
- the string form
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.- Overrides:
isCompilablein classSpelNodeImpl- Returns:
trueif this node can be compiled to bytecode
generateCode
public void generateCode(MethodVisitor mv, CodeFlow cf)
Description copied from class:SpelNodeImplGenerate the bytecode for this node into the supplied visitor. Context info about the current expression being compiled is available in the codeflow object, e.g. including information about the type of the object currently on the stack.- Overrides:
generateCodein classSpelNodeImpl- Parameters:
mv- the ASM MethodVisitor into which code should be generatedcf- a context object with info about what is on the stack
