构造器详细资料

CmsPair

public CmsPair()

Serialization constructor.

CmsPair

public CmsPair(A a,
       B b)

Creates a new pair containing two objects.

参数:

a - the first component

b - the second component

方法详细资料

create

public static <A,B> CmsPair<A,B> create(A a,
                        B b)

Helper method for constructing a pair which avoids having to explicitly write the generic type parameters.

类型参数:

A - the type for the first component

B - the type for the second component

参数:

a - the first component

b - the second component

返回:

the pair (a, b)

getLexicalComparator

public static <A extends java.lang.Comparable<A>,B extends java.lang.Comparable<B>> java.util.Comparator<CmsPair<A,B>> getLexicalComparator()

Utility method which creates a new comparator for lexically ordering pairs.

Lexical ordering means that a pair is considered "less" than another if either its first component is less than that of the other one, or their first components are equal and the second component of the first pair is less than that of the other one.

类型参数:

A - the type parameter for the first pair component

B - the type parameter for the second pair component

返回:

a new comparator for lexically ordering pairs

pairsToMap

public static java.util.Map<java.lang.String,java.lang.String> pairsToMap(java.util.List<CmsPair<java.lang.String,java.lang.String>> pairs)

Helper method for converting a list of string pairs to a string map.

The first component of each pair is used as a map key, the second component as the value for the key.

参数:

pairs - the list of pairs

返回:

a string map

equals

public boolean equals(java.lang.Object o)

覆盖:

equals 在类中 java.lang.Object

getFirst

public A getFirst()

Returns the first component of the pair.

返回:

the first component of the pair

getSecond

public B getSecond()

Returns the second component of the pair.

返回:

the second component of the pair

hashCode

public int hashCode()

覆盖:

hashCode 在类中 java.lang.Object
