Method Detail

createRef

public Expr createRef(QuercusParser parser)

Returns the reference of the value.

Overrides:

createRef in class Expr

Parameters:

location -

createCopy

public Expr createCopy(ExprFactory factory)

Returns the copy of the value.

Overrides:

createCopy in class Expr

Parameters:

location -

eval

public Value eval(Env env)

Description copied from class: Expr

Evaluates the expression, returning a Value, never a Var.

Specified by:

eval in class Expr

Parameters:

env - the calling environment.

Returns:

the expression value.

evalRef

public Value evalRef(Env env)

Description copied from class: Expr

Evaluates the expression, returning a Var for variables, and a Value for values.

Overrides:

evalRef in class Expr

Parameters:

env - the calling environment.

Returns:

the expression value.

evalCopy

public Value evalCopy(Env env)

Description copied from class: Expr

Evaluates the expression as a copy. The default is not to copy because the absence of copying is more testable.

Overrides:

evalCopy in class Expr

Parameters:

env - the calling environment.

Returns:

the expression value.

evalImpl

public Value evalImpl(Env env,
                      boolean isRef,
                      boolean isCopy)

Evaluates the expression.

Parameters:

env - the calling environment.

Returns:

the expression value.
