This rule is defined by the following XPath expression:
//PrimaryExpression [PrimaryPrefix/Name[ends-with(@Image, 'toArray')]] [ PrimarySuffix/Arguments/ArgumentList/Expression /PrimaryExpression/PrimaryPrefix/AllocationExpression /ArrayDimsAndInits/Expression/PrimaryExpression/PrimaryPrefix/Literal[@Image='0'] ]
Example:
class Foo { void bar(Collection x) { // A bit inefficient x.toArray(new Foo[0]); // Much better; this one sizes the destination array, avoiding // a reflection call in some Collection implementations x.toArray(new Foo[x.size()]); } }
