Class DynamicTablesHelper.CacheKey.IndexKey

java.lang.Object

com.goldencode.p2j.persist.DynamicTablesHelper.CacheKey.IndexKey

Enclosing class:

DynamicTablesHelper.CacheKey

private static class DynamicTablesHelper.CacheKey.IndexKey
extends java.lang.Object

Instances of this class are used to wrap instances of P2JIndex, for purposes of producing hash codes suitable for using instances of the enclosing class as hash map keys. This class provides stricter implementations of hashCode and equals than those provided by P2JIndex itself.

Field Detail

index

private final P2JIndex index

The wrapped instance of an index definition

Constructor Detail

IndexKey

IndexKey(P2JIndex index)

Constructor.

Parameters:

index - Index definition to be wrapped.

Method Detail

hashCode

public int hashCode()

Use the content of the wrapped index definition to produce a hash code. This is used instead of P2JIndex.hashCode(), because the latter implementation of this method is special-purpose, taking only the names of index components into account and ignores other index metadata.

Overrides:

hashCode in class java.lang.Object

Returns:

Hash code.

equals

public boolean equals(java.lang.Object o)

Overrides the default implementation to provide an implementation consistent with hashCode().

Overrides:

equals in class java.lang.Object

Returns:

true if this object is equivalent with o, else false.

toString

public java.lang.String toString()

To string method returning the string value of this objects P2JIndex field.

Overrides:

toString in class java.lang.Object

Returns:

string value of this IndexKey object.
