Method Details

getExpression

public TExpression getExpression()

A combination of variables, constants, literals, operators, and function calls. The simplest expression consists of a single variable. When the RETURN statement is executed, the value of expression is assigned to the function identifier.

Returns:

init

public void init(Object arg1)

Description copied from class: TParseTreeNode

Initialize a query tree node. Used internally

Overrides:

init in class TParseTreeNode

Parameters:

arg1 - first argument

doParseStatement

public int doParseStatement(TCustomSqlStatement psql)

Overrides:

doParseStatement in class TCustomSqlStatement

accept

public void accept(TParseTreeVisitor v)

Description copied from class: TParseTreeNode

Accept a visitor

Specified by:

accept in interface Visitable

Overrides:

accept in class TParseTreeNode

Parameters:

v - visitor is a descendant class of TParseTreeVisitor

acceptChildren

public void acceptChildren(TParseTreeVisitor v)

Description copied from class: TParseTreeNode

Accept a visitor to iterate this class and sub-nodes of this class

Specified by:

acceptChildren in interface Visitable

Overrides:

acceptChildren in class TParseTreeNode

Parameters:

v - visitor is a descendant class of TParseTreeVisitor

setExpression

public void setExpression(TExpression expression)
