Method Detail

evaluateNode

protected Object evaluateNode(Object o)
                       throws Exception
Description copied from class: SimpleNode
Evaluates itself with object, pushing result on the stack.

Specified by:
evaluateNode in class SimpleNode
Throws:
Exception

shallowCopy

public Expression shallowCopy()
Creates a copy of this expression node, without copying children.

Specified by:
shallowCopy in class Expression

getType

public int getType()
Description copied from class: Expression
Returns a type of expression. Most common types are defined as public static fields of this interface.

Overrides:
getType in class Expression

encodeAsString

public void encodeAsString(PrintWriter pw)
Description copied from class: Expression
Stores a String representation of Expression using a provided PrintWriter.

Overrides:
encodeAsString in class SimpleNode

encodeAsEJBQL

public void encodeAsEJBQL(PrintWriter pw,
                          String rootId)
Description copied from class: Expression
Stores a String representation of Expression as EJBQL using a provided PrintWriter. DB path expressions produce non-standard EJBQL path expressions.

Overrides:
encodeAsEJBQL in class SimpleNode
Since:
3.0

getExpressionOperator

protected String getExpressionOperator(int index)
Specified by:
getExpressionOperator in class SimpleNode
