类

说明

class

Assign

Represents assignment.

class

BeanReference

Represents a bean reference to a type, for example @foo or @'foo.bar'.

class

BooleanLiteral

Represents the literal values TRUE and FALSE.

class

CompoundExpression

Represents a DOT separated expression sequence, such as property1.property2.methodOne() or property1?.property2?.methodOne() when the null-safe navigation operator is used.

class

ConstructorReference

Represents the invocation of a constructor.

class

Elvis

Represents the Elvis operator ?
class FloatLiteral Expression language AST node that represents a float literal. class FunctionReference A function reference is of the form "#someFunction(a,b,c)". class Identifier An 'identifier' SpelNode. class Indexer An Indexer can index into some proceeding structure to access a particular piece of it. class InlineList Represent a list in an expression, e.g. '{1,2,3}' class InlineMap Represent a map in an expression, e.g. class IntLiteral Expression language AST node that represents an integer literal. class Literal Common superclass for nodes representing literals (boolean, string, number, etc). class LongLiteral Expression language AST node that represents a long integer literal. class MethodReference Expression language AST node that represents a method reference. class NullLiteral Expression language AST node that represents null. class OpAnd Represents the boolean AND operation. class OpDec Decrement operator. class OpDivide Implements division operator. class OpEQ Implements the equality operator. class Operator Common supertype for operators that operate on either one or two operands. class OperatorBetween Represents the between operator. class OperatorInstanceof The operator 'instanceof' checks if an object is of the class specified in the right hand operand, in the same way that instanceof does in Java. class OperatorMatches Implements the matches operator. class OperatorNot Represents a NOT operation. class OperatorPower The power operator. class OpGE Implements greater-than-or-equal operator. class OpGT Implements the greater-than operator. class OpInc Increment operator. class OpLE Implements the less-than-or-equal operator. class OpLT Implements the less-than operator. class OpMinus The minus operator supports: subtraction of numbers subtraction of an int from a string of one character (effectively decreasing that character), so 'd'-3='a' class OpModulus Implements the modulus operator. class OpMultiply Implements the multiply operator. class OpNE Implements the not-equal operator. class OpOr Represents the boolean OR operation. class OpPlus The plus operator will: add numbers concatenate strings class Projection Represents projection, where a given operation is performed on all elements in some input sequence, returning a new sequence of the same size. class PropertyOrFieldReference Represents a simple property or field reference. class QualifiedIdentifier Represents a dot separated sequence of strings that indicate a package qualified type reference. class RealLiteral Expression language AST node that represents a real literal. class Selection Represents selection over a map or collection. class StringLiteral Expression language AST node that represents a string literal. class Ternary Represents a ternary expression, for example: "someCheck()? class TypeReference Represents a reference to a type, for example "T(String)" or "T(com.somewhere.Foo)". class VariableReference Represents a variable reference — for example, #someVar.
