Constructor Detail

ArrayAccessExpr

public ArrayAccessExpr(Expression array,
                       Expression index,
                       SourceType type,
                       SourceLocation location)

Creates an array access over the given array and index and reparents both operands.

Parameters:

array - the array operand

index - the index operand

type - the element type produced by the access

location - the source location, or null for unknown

Throws:

NullPointerException - if array, index, or type is null
