Method Summary

Modifier and Type	Method	Description
Map<String,String>	asContext(List<String> dimensions)
int	compareTo(DimensionValues other)	Implements the sort order of this which is based on specificity where dimensions to the left are more significant: -1 is returned if this is more specific than other, 1 is returned if other is more specific than this, 0 is returned if none is more specific than the other.
static DimensionValues	createFrom(String[] values)
boolean	equals(Object o)
String	get(int index)	Returns the string at the given index, or null if it has no value at this index
String[]	getValues()	Returns a copy of the values in this in an array
int	hashCode()
boolean	isEmpty()
boolean	isMoreSpecificThan(DimensionValues other)	Helper method which uses compareTo to return whether this is most specific
boolean	matches(DimensionValues givenValues)	Returns true if this is has the same value every place it has a value as the given values.
int	size()	Returns the number of values in this (some of which may be null)

public static final DimensionValues empty

Method Details

createFrom

public static DimensionValues createFrom(String[] values)

matches

public boolean matches(DimensionValues givenValues)

Returns true if this is has the same value every place it has a value as the given values.

compareTo

public int compareTo(DimensionValues other)

Implements the sort order of this which is based on specificity where dimensions to the left are more significant: -1 is returned if this is more specific than other, 1 is returned if other is more specific than this, 0 is returned if none is more specific than the other.

Note: This ordering is not consistent with equals - it returns 0 when the same dimensions are set, regardless of what they are set to.

Specified by:

compareTo in interface Comparable<DimensionValues>

isMoreSpecificThan

public boolean isMoreSpecificThan(DimensionValues other)

Helper method which uses compareTo to return whether this is most specific

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

isEmpty

public boolean isEmpty()

asContext

public Map<String,String> asContext(List<String> dimensions)

get

public String get(int index)

Returns the string at the given index, or null if it has no value at this index

size

public int size()

Returns the number of values in this (some of which may be null)

getValues

public String[] getValues()

Returns a copy of the values in this in an array
