方法详细资料

computeConstant

@Nullable
private TypedValue computeConstant()

If all the components of the list are constants, or lists that themselves contain constants, then a constant list can be built to represent this node. This will speed up later getValue calls and reduce the amount of garbage created.

getValueInternal

public TypedValue getValueInternal(ExpressionState expressionState)
                            throws EvaluationException

指定者:

getValueInternal 在类中 SpelNodeImpl

抛出:

EvaluationException

toStringAST

public String toStringAST()

从接口复制的说明: SpelNode

Return the string form the this AST node.

返回:

the string form

isConstant

public boolean isConstant()

Return whether this list is a constant value.

getConstantValue

@Nullable
public List<Object> getConstantValue()

isCompilable

public boolean isCompilable()

从类复制的说明: 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.

覆盖:

isCompilable 在类中 SpelNodeImpl

返回:

true if this node can be compiled to bytecode

generateCode

public void generateCode(MethodVisitor mv,
 CodeFlow codeflow)

从类复制的说明: SpelNodeImpl

Generate 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.

覆盖:

generateCode 在类中 SpelNodeImpl

参数:

mv - the ASM MethodVisitor into which code should be generated

codeflow - a context object with info about what is on the stack

generateClinitCode

void generateClinitCode(String clazzname,
 String constantFieldName,
 MethodVisitor mv,
 CodeFlow codeflow,
 boolean nested)
