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}

  • 构造器详细资料

    • 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 generated
      cf - a context object with info about what is on the stack
