Constructor Detail

ResourceID

public ResourceID(String resourceURN)

Constructor.

Parameters

resourceURN - the URN of the referrent resource

ResourceID

protected ResourceID(ResourceIDBuilder builder)

Constructor.

Parameters

builder - the ResourceIDBuilder (must not be null)

Method Detail

narrow

public static <T extends ResourceID> T narrow(Class<T> type,
                                              ResourceID resourceID)
                                   throws ResourceIDException

Convert the given ResourceID to an instance of the specified ResourceID type.

Parameters

type - the desired ResourceID type

resourceID - the ResourceID

Returns

the narrowed ResourceID

Throws

ResourceIDException

hashCode

public final int hashCode()

Get the hash code of this ResourceID.

The hash code is computed from the URN of the referrent resource.

Overrides:

hashCode in class Object

Returns

the hash code of this ResourceID

equals

public final boolean equals(Object that)

Determine if the given Object is equal to this ResourceID.

The given Object is considered to be equal to this ResourceID if and only if all of these statements are true:

1. The given Object is an instance of ResourceID or a subtype of ResourceID.
2. The given Object (a ResourceID) has a ResourceType that equals the ResourceType of this ResourceID.
3. The given Object (a ResourceID) has a resource URN that is identical to the resource URN.

Overrides:

equals in class Object

Returns

true if the given Object is equal to this ResourceID and false otherwise

getResourceIDBuilder

protected ResourceIDBuilder getResourceIDBuilder()

Get the ResourceIDBuilder.

Returns

the the ResourceIDBuilder

getResourceType

public final ResourceType getResourceType()

Get the ResourceType of the referrent resource.

Returns

the ResourceType of the referrent resource

getResourceEnvironment

public ResourceEnvironment getResourceEnvironment()

Get the ResourceEnvironment of the referrent resource.

Returns

the ResourceEnvironment of the referrent resource

getResourceURN

public final String getResourceURN()

Get the URN of the referrent resource.

Returns

the URN of the referrent resource

setResourceURN

protected void setResourceURN(String resourceURN)

getCanonicalResourceURN

public final String getCanonicalResourceURN()

Deprecated use getResourceURN()

Get the canonical URN of the referrent resource.

This method may return null if the resource type is invalid or unknown.

Returns

the canonical URN of the referrent resource

setCanonicalResourceURN

protected void setCanonicalResourceURN(String canonicalResourceURN)

computeResourceURN

protected String computeResourceURN()

Compute the URN of the referrent resource.

Returns

the URN of the referrent resource

computeResourceURN

protected StringBuilder computeResourceURN(StringBuilder buffer)

Compute the URN of the referrent resource.

Parameters

buffer - the StringBuilder for the URN of the referrent resource

Returns

the StringBuilder with the URN of the referrent resource appended to it

appendResourceTypeNamespaceURI

protected StringBuilder appendResourceTypeNamespaceURI(StringBuilder buffer)

Append the namespace URI of the ResourceType.

Parameters

buffer - the StringBuilder for the namespace URI of the ResourceType

Returns

the StringBuilder with the namespace URI of the ResourceType appended to it

appendResourcePath

protected abstract StringBuilder appendResourcePath(boolean canonicalResourceURN,
                                                    StringBuilder buffer)

Append the resource path of the referrent resource.

Parameters

buffer - the StringBuilder for the resource path of the referrent resource

canonicalResourceURN - indicates if the canonical resource URN should be computed. Since this is no longer supported this should always be true.

Returns

the StringBuilder with the resource path of the referrent resource appended to it

toString

public final String toString()

Get a string representation of this ResourceID.

This method returns the URN of the referrent resource.

Overrides:

toString in class Object

Returns

a string representation of this ResourceID
