类 ConstructorReference
- java.lang.Object
- org.springframework.expression.spel.ast.SpelNodeImpl
- org.springframework.expression.spel.ast.ConstructorReference
public class ConstructorReference extends SpelNodeImpl
Represents the invocation of a constructor. Either a constructor on a regular type or construction of an array. When an array is constructed, an initializer can be specified.Examples:
new String('hello world')
new int[]{1,2,3,4}
new int[3] new int[3]{1,2,3}- 从以下版本开始:

ConstructorReference
public ConstructorReference(int startPos, int endPos, SpelNodeImpl... arguments)
Create a constructor reference. The first argument is the type, the rest are the parameters to the constructor call
ConstructorReference
public ConstructorReference(int startPos, int endPos, SpelNodeImpl[] dimensions, SpelNodeImpl... arguments)
Create a constructor reference. The first argument is the type, the rest are the parameters to the constructor call
方法详细资料
getValueInternal
public TypedValue getValueInternal(ExpressionState state) throws EvaluationException
Implements getValue() - delegating to the code for building an array or a simple type.- 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
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 cf)
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 generatedcf
- a context object with info about what is on the stack
