Methods

Modifier and Type	Method and Description
Type	baseType()
Type	baseTypeRef()
Expression	copy() Returns a deep copy of this expression.
Expression[]	elements()
int	kind()
int	numberOfSubexpressions() Returns the number of subexpressions
void	setCheckedType() This method sets the final unambiguously checked type of this expression, possibly along with other final information that may be needed by the compiler for generating code.
Expression	setSubexpression(int n, Expression expression) Returns this expression after setting its n-th subexpression to the specified expression; if there is no subexpression at the given position, this throws a NoSuchSubexpressionException
Expression	subexpression(int n) Returns the n-th subexpression of this expression; if there is no subexpression at the given position, this throws a NoSuchSubexpressionException
Expression	typedCopy() Returns a deep copy of this expression this and all its subexpressions share the same type as their copy's counterparts.

Method Detail

kind

public final int kind()

copy

public final Expression copy()

Description copied from class: Expression

Returns a deep copy of this expression. The types are not not copied. NB: This is a convenience for building expressions that should be used exclusively before any processing (in particular sanitizing), is done on this expression.

Specified by:

copy in class Expression

typedCopy

public final Expression typedCopy()

Description copied from class: Expression

Returns a deep copy of this expression this and all its subexpressions share the same type as their copy's counterparts. NB: This is a convenience for building expressions that should be used exclusively before any processing (in particular sanitizing), is done on this expression.

Specified by:

typedCopy in class Expression

numberOfSubexpressions

public final int numberOfSubexpressions()

Description copied from class: Expression

Returns the number of subexpressions

Overrides:

numberOfSubexpressions in class Expression

subexpression

public final Expression subexpression(int n)
                               throws NoSuchSubexpressionException

Description copied from class: Expression

Returns the n-th subexpression of this expression; if there is no subexpression at the given position, this throws a NoSuchSubexpressionException

Overrides:

subexpression in class Expression

Throws:

NoSuchSubexpressionException

setSubexpression

public final Expression setSubexpression(int n,
                          Expression expression)
                                  throws NoSuchSubexpressionException

Description copied from class: Expression

Returns this expression after setting its n-th subexpression to the specified expression; if there is no subexpression at the given position, this throws a NoSuchSubexpressionException

Overrides:

setSubexpression in class Expression

Throws:

NoSuchSubexpressionException

elements

public final Expression[] elements()

baseType

public final Type baseType()

baseTypeRef

public final Type baseTypeRef()

setCheckedType

public final void setCheckedType()

Description copied from class: Expression

This method sets the final unambiguously checked type of this expression, possibly along with other final information that may be needed by the compiler for generating code.

Specified by:
