Constructor Detail
OperatorNot
public OperatorNot(int startPos, int endPos, SpelNodeImpl operand)
Method Detail
getValueInternal
public BooleanTypedValue getValueInternal(ExpressionState state) throws EvaluationException
- Specified by:
getValueInternal
in classSpelNodeImpl
- Throws:
EvaluationException
toStringAST
public String toStringAST()
Description copied from interface:SpelNode
Return the string form the this AST node.- Returns:
- the string form
isCompilable
public boolean isCompilable()
Description copied from class:SpelNodeImpl
Check whether a node can be compiled to bytecode. The reasoning in each node may be different but will typically involve checking whether the exit type descriptor of the node is known and any relevant child nodes are compilable.- Overrides:
isCompilable
in classSpelNodeImpl
- Returns:
true
if this node can be compiled to bytecode
generateCode
public void generateCode(MethodVisitor mv, generateCode in class
SpelNodeImpl
- Parameters:
mv
- the ASM MethodVisitor into which code should be generatedcf
- a context object with info about what is on the stack
