 Expression baseExpression)

Method Details

printSQL

public void printSQL(ExpressionSQLPrinter printer)

Description copied from class: ConstantExpression

INTERNAL: Print SQL onto the stream, using the ExpressionPrinter for context

Overrides:

printSQL in class ConstantExpression

valueFromObject

public Object valueFromObject(Object object,
 AbstractSession session,
 AbstractRecord translationRow,
 int valueHolderPolicy,
 boolean isObjectUnregistered)

INTERNAL: Return the value for in memory comparison. This is only valid for valueable expressions.

Overrides:

valueFromObject in class ConstantExpression

Parameters:

isObjectUnregistered - true if object possibly not a clone, but is being conformed against the unit of work cache.

setLocalBase

public void setLocalBase(Expression e)

Description copied from class: Expression

INTERNAL: Set the local base expression, ie the one on the other side of the operator Most types will ignore this, since they don't need it.

Overrides:

setLocalBase in class ConstantExpression

postCopyIn

protected void postCopyIn(Map alreadyDone)

INTERNAL: Used for cloning.

Overrides:

postCopyIn in class ConstantExpression
