Constructor Detail

ArraySpecifier

public ArraySpecifier()

Constructs a new array specifier with an empty dimension.

ArraySpecifier

public ArraySpecifier(Expression expr)

Constructs a new array specifier with the given dimension expression.

Parameters:

expr - the dimension expression.

ArraySpecifier

public ArraySpecifier(java.util.List dimensions)

Constructs a new array specifier with the given dimension expressions.

Parameters:

dimensions - the list of dimension expressions.

Method Detail

getDimension

public Expression getDimension(int n)

Gets the nth dimension of this array specifier.

Parameters:

n - The position of the dimension.

Returns:

the nth dimension, which may be null. A null dimension occurs for example with int array[][8].

Throws:

java.lang.IndexOutOfBoundsException - if there is no expression at that position.

getNumDimensions

public int getNumDimensions()

Returns the number of index expressions used in this array specifier.

Returns:

the number of index expressions.

print

public void print(java.io.PrintWriter o)

Description copied from class: Specifier

Prints the specifier to the print writer.

Specified by:

print in interface Printable

Overrides:

print in class Specifier

Parameters:

o - The writer on which to print the data.

setDimension

public void setDimension(int n,
                Expression expr)

Sets the nth dimension of this array specifier.

Parameters:

n - The position of the dimension.

expr - The expression defining the size of the dimension.

Throws:

java.lang.IndexOutOfBoundsException - if there is no dimension at that position.

setDimensions

public void setDimensions(java.util.List dimensions)

Set the list of dimension expressions.

Parameters:

dimensions - A list of expressions.
