isNullSafe
public boolean isNullSafe() -
getName
-
getValueRef
- 覆盖:
getValueRef在类中SpelNodeImpl- 抛出:
EvaluationException
-
getValueInternal
- 指定者:
getValueInternal在类中SpelNodeImpl- 抛出:
EvaluationException
-
setValue
从接口复制的说明:SpelNodeEvaluate the expression to a node and then set the new value on that node. For example, if the expression evaluates to a property reference, then the property will be set to the new value.- 指定者:
setValue在接口中SpelNode- 覆盖:
setValue在类中SpelNodeImpl- 参数:
state- the current expression state (includes the context)newValue- the new value- 抛出:
EvaluationException- if any problem occurs evaluating the expression or setting the new value
-
isWritable
从接口复制的说明:SpelNodeDetermine if this expression node will support a setValue() call.- 指定者:
isWritable在接口中SpelNode- 覆盖:
isWritable在类中SpelNodeImpl- 参数:
state- the current expression state (includes the context)- 返回:
- true if the expression node will allow setValue()
- 抛出:
EvaluationException- if something went wrong trying to determine if the node supports writing
-
toStringAST
从接口复制的说明:SpelNodeReturn the string form the this AST node.- 返回:
- the string form
-
isWritableProperty
public boolean isWritableProperty(String name, TypedValue contextObject, EvaluationContext evalContext) throws EvaluationException -
isCompilable
public boolean isCompilable()从类复制的说明:SpelNodeImplCheck 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:
trueif this node can be compiled to bytecode
-
generateCode
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, 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 generatedcf- a context object with info about what is on the stack
