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.OutputStream stream)

Description copied from interface: Printable

Print the code for the IR represented by the object. Always calls object_print_method(this, stream). If the object's print method is null, nothing is printed; this provides an easy mechanism to temporarily hide something.

Specified by:

print in interface Printable

Overrides:

print in class Specifier

Parameters:

stream - The stream on which to print the data.

toString

public java.lang.String toString()

Overrides:

toString in class Specifier

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.
