Class 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}- Since:
- 3.0

Constructor Detail
ConstructorReference
public ConstructorReference(int pos, 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 pos, SpelNodeImpl[] dimensions, SpelNodeImpl... arguments)
Create a constructor reference. The first argument is the type, the rest are the parameters to the constructor call
Method Detail
getValueInternal
public TypedValue getValueInternal(ExpressionState state) throws EvaluationException
Implements getValue() - delegating to the code for building an array or a simple type.- Specified by:
getValueInternalin classSpelNodeImpl- Throws:
EvaluationException
toStringAST
public String toStringAST()
- Returns:
- the string form of this AST node
isCompilable
public boolean isCompilable()
Description copied from class: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.- Overrides:
isCompilablein classSpelNodeImpl- Returns:
trueif this node can be compiled to bytecode
generateCode
public void generateCode(MethodVisitor mv, CodeFlow cf)
Description copied from class:SpelNodeImplGenerate the bytecode for this node into the supplied visitor. Context info about the current expression being compiled is available in the codeflow object. For example it will include information about the type of the object currently on the stack.- Overrides:
generateCodein classSpelNodeImpl- Parameters:
mv- the ASM MethodVisitor into which code should be generatedcf- a context object with info about what is on the stack
