SpEL's abstract syntax tree.
Interface Summary Interface Description ValueRef Represents a reference to a value.Class Summary Class Description Assign Represents assignment.AstUtils Utilities methods for use in the Ast classes.BeanReference Represents a bean reference to a type, for example @foo or @'foo.bar'.BooleanLiteral Represents the literal valuesTRUEandFALSE.CompoundExpression Represents a DOT separated expression sequence, such as'property1.property2.methodOne()'.ConstructorReference Represents the invocation of a constructor.Elvis Represents the elvis operator ?:.FloatLiteral Expression language AST node that represents a float literal.FunctionReference A function reference is of the form "#someFunction(a,b,c)".Identifier An 'identifier'SpelNode.Indexer An Indexer can index into some proceeding structure to access a particular piece of it.InlineList Represent a list in an expression, e.g.InlineMap Represent a map in an expression, e.g.IntLiteral Expression language AST node that represents an integer literal.Literal Common superclass for nodes representing literals (boolean, string, number, etc).LongLiteral Expression language AST node that represents a long integer literal.MethodReference Expression language AST node that represents a method reference.NullLiteral Expression language AST node that represents null.OpAnd Represents the boolean AND operation.OpDec Decrement operator.OpDivide Implements division operator.OpEQ Implements the equality operator.Operator Common supertype for operators that operate on either one or two operands.Operator.DescriptorComparison A descriptor comparison encapsulates the result of comparing descriptor for two operands and describes at what level they are compatible.OperatorBetween Represents the between operator.OperatorInstanceof The operator 'instanceof' checks if an object is of the class specified in the right hand operand, in the same way thatinstanceofdoes in Java.OperatorMatches Implements the matches operator.OperatorNot Represents a NOT operation.OperatorPower The power operator.OpGE Implements greater-than-or-equal operator.OpGT Implements the greater-than operator.OpInc Increment operator.OpLE Implements the less-than-or-equal operator.OpLT Implements the less-than operator.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'OpModulus Implements the modulus operator.OpMultiply Implements themultiplyoperator.OpNE Implements the not-equal operator.OpOr Represents the boolean OR operation.OpPlus The plus operator will: add numbers concatenate stringsProjection Represents projection, where a given operation is performed on all elements in some input sequence, returning a new sequence of the same size.PropertyOrFieldReference Represents a simple property or field reference.QualifiedIdentifier Represents a dot separated sequence of strings that indicate a package qualified type reference.RealLiteral Expression language AST node that represents a real literal.Selection Represents selection over a map or collection.SpelNodeImpl The common supertype of all AST nodes in a parsed Spring Expression Language format expression.StringLiteral Expression language AST node that represents a string literal.Ternary Represents a ternary expression, for example: "someCheck()?true:false".TypeReference Represents a reference to a type, for example"T(String)" or "T(com.somewhere.Foo)".ValueRef.NullValueRef A ValueRef for the null value.ValueRef.TypedValueHolderValueRef A ValueRef holder for a single value, which cannot be set.VariableReference Represents a variable reference, eg.Enum Summary Enum Description TypeCode Captures primitive types and their corresponding class objects, plus one special entry that represents all reference (non-primitive) types.
