Package org.pentaho.reporting.libraries.resourceloader

Class ResourceKey

java.lang.Object

org.pentaho.reporting.libraries.resourceloader.ResourceKey

All Implemented Interfaces:

Serializable

public final class ResourceKey
extends Object
implements Serializable

The key is an unique identifier for the resource. Most of the time, this may be an URL, but other (especially database based) schemas are possible.

A resource key must provide an 'equals' implementation. ResourceKeys should be implemented as immutable classes, so that they can be safely stored in collections or on external storages (like caches).

ResourceKey

public ResourceKey(Object schema,
                   Object identifier,
                   Map<? extends ParameterKey,Object> factoryParameters)

ResourceKey

public ResourceKey(ResourceKey parent,
                   Object schema,
                   Object identifier,
                   Map<? extends ParameterKey,Object> factoryParameters)

Method Detail

createAsDerived

public static ResourceKey createAsDerived(ResourceKey parent,
                                          ResourceKey child)

getParent

public ResourceKey getParent()

getFactoryParameters

public Map<ParameterKey,Object> getFactoryParameters()

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getIdentifier

public Object getIdentifier()

getIdentifierAsString

public String getIdentifierAsString()

Returns a String version of the identifier.

Returns:

the identifier as string or null, if the identifier could not be converted easily.

getSchema

public Object getSchema()

Returns the schema of this resource key. The schema is an internal identifier to locate the resource-loader implementation that was responsible for creating the key in the first place.

The schema has no meaning outside the resource loading framework.

Returns:

toString

public String toString()

Overrides:

toString in class Object
