evaluateNode
Description copied from class:SimpleNodeEvaluates itself with object, pushing result on the stack.- Specified by:
evaluateNodein classSimpleNode- Throws:
Exception
-
shallowCopy
Creates a copy of this expression node, without copying children.- Specified by:
shallowCopyin classExpression
-
appendAsEJBQL
public void appendAsEJBQL(List<Object> parameterAccumulator, Appendable out, String rootId) throws IOExceptionDescription copied from class:ExpressionStores a String representation of Expression as EJBQL using a provided PrintWriter. DB path expressions produce non-standard EJBQL path expressions. If the parameterAccumulator is supplied then as the EJBQL is output, it may load parameters into this list. In this case, the EJBQL output will contain reference to positional parameters. If no parameterAccumulator is supplied and a scalar type is encountered for which there is no EJBQL literal representation (such as dates) then this method will throw a runtime exception to indicate that it was not possible to generate a string-only representation of the Expression in EJBQL.- Overrides:
appendAsEJBQLin classSimpleNode- Throws:
IOException- Since:
- 4.0
-
appendAsString
Description copied from class:ExpressionAppends own content as a String to the provided Appendable.- Overrides:
appendAsStringin classSimpleNode- Throws:
IOException- Since:
- 4.0
-
getType
public int getType()Description copied from class:ExpressionReturns a type of expression. Most common types are defined as public static fields of this interface.- Overrides:
