Class PropertyCombinations

java.lang.Object

com.google.gwt.dev.cfg.PropertyCombinations

All Implemented Interfaces:

Iterable<String[]>

public class PropertyCombinations
extends Object
implements Iterable<String[]>

Generates all possible permutations of properties in a module. Each permutation consists of the list of active property values associated with that permutation. That list of property values is represented as an array of Strings corresponding to the list of properties returned by Properties.getBindingProperties().

Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
static class	PropertyCombinations.PermutationDescription A bundle of the ordered names of binding and configuration properties and a single set value for each that together uniquely identify a particular permutation.

Constructor Summary

Constructors

Constructor and Description
PropertyCombinations(Properties properties, Set<String> activeLinkerNames)
PropertyCombinations(PropertyCombinations allPermutations, List<String[]> values) Copy constructor that allows the list of property values to be reset.

Method Summary

Modifier and Type	Method and Description
List<PropertyCombinations>	collapseProperties() Return a list of PropertyPermutations that represent the hard permutations that result from collapsing the soft properties in the PropertyPermutation's Properties object.
BindingProperty[]	getOrderedProperties() Returns the properties used to generate permutations.
String[]	getOrderedPropertyValues(int permutation) Returns the value of each property used to generate the given permutation.
PropertyCombinations.PermutationDescription	getPermutationDescription(int permutationId) Returns a unique description for the given permutation.
Iterator<String[]>	iterator() Enumerates each permutation as an array of strings such that the index of each string in the array corresponds to the property at the same index in the array returned from getOrderedProperties().
int	size()

Copy constructor that allows the list of property values to be reset.

Method Detail

collapseProperties

public List<PropertyCombinations> collapseProperties()

Return a list of PropertyPermutations that represent the hard permutations that result from collapsing the soft properties in the PropertyPermutation's Properties object.

getOrderedProperties

public BindingProperty[] getOrderedProperties()

Returns the properties used to generate permutations. (Parallel to getOrderedPropertyValues(int).)

getOrderedPropertyValues

public String[] getOrderedPropertyValues(int permutation)

Returns the value of each property used to generate the given permutation. (Parallel to getOrderedProperties().)

getPermutationDescription

public PropertyCombinations.PermutationDescription getPermutationDescription(int permutationId)

Returns a unique description for the given permutation.

iterator

public Iterator<String[]> iterator()

Enumerates each permutation as an array of strings such that the index of each string in the array corresponds to the property at the same index in the array returned from getOrderedProperties().

Specified by:

iterator in interface Iterable<String[]>

size
