Method Detail

checkIfConstant

private void checkIfConstant()

If all the components of the list are constants, or lists that themselves contain constants, then a constant list can be built to represent this node. This will speed up later getValue calls and reduce the amount of garbage created.

getValueInternal

public TypedValue getValueInternal(ExpressionState expressionState)
                            throws EvaluationException

Specified by:

getValueInternal in class SpelNodeImpl

Throws:

EvaluationException

toStringAST

public java.lang.String toStringAST()

Specified by:

toStringAST in interface SpelNode

Specified by:

toStringAST in class SpelNodeImpl

Returns:

the string form of this AST node

isConstant

public boolean isConstant()

Returns:

whether this list is a constant value

getConstantValue

private java.util.List<java.lang.Object> getConstantValue()
