Class ConstructorReference
java.lang.Object
org.springframework.expression.spel.ast.SpelNodeImpl
org.springframework.expression.spel.ast.ConstructorReference
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 example.Foo()
new String('hello world')
new int[] {1,2,3,4}
new String[] {'abc','xyz'}
new int[5]
new int[3][4]

ConstructorReference
Create a constructor reference for a regular type.The first argument is the type. The rest are the arguments to the constructor.

ConstructorReference
public ConstructorReference(int startPos, int endPos, SpelNodeImpl[] dimensions, SpelNodeImpl... arguments) Create a constructor reference for an array.The first argument is the array component type. The second argument is an
InlineList
representing the array initializer, if an initializer was supplied in the expression.

Method Details
-
getValueInternal
Implements getValue() - delegating to the code for building an array or a simple type.- Specified by:
getValueInternal
in classSpelNodeImpl
- Throws:
EvaluationException
-
toStringAST
Description copied from interface:SpelNode
Return the string form of this AST node.- Returns:
- the string form
-
isCompilable
public boolean isCompilable()Description copied from class: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.- Overrides:
isCompilable
in classSpelNodeImpl
- Returns:
true
if this node can be compiled to bytecode
-
generateCode
Description copied from class: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.- Overrides:
generateCode
in classSpelNodeImpl
- Parameters:
mv
- the ASM MethodVisitor into which code should be generatedcf
- a context object with info about what is on the stack
