AttribReferencePart

public AttribReferencePart(java.lang.Object v)

Constructs AttribReferencePart with a attribute.

Parameters:

v - value for attrib part

Method Detail

asAttribReferencePart

public ReferencePart asAttribReferencePart()

Returns this object since this is already an attrib reference part. Overrides HereReferencePart.asAttribReferencePart.

Overrides:

asAttribReferencePart in class HereReferencePart

Returns:

this part

toString

public java.lang.String toString()

Returns a string representation of the reference part. Overrides HereReferencePart.toString.

Overrides:

toString in class HereReferencePart

Returns:

stringified reference part

toString

public java.lang.String toString(int index)

Return a string which is a representation of the reference part in a reference in the index position given.

Overrides:

toString in class HereReferencePart

Parameters:

index - the position in the reference

Returns:

the representation

hashCode

public int hashCode()

Returns hashcode of this part. This is the hashCode of the stored value plus the ATTRIB hashcode

Overrides:

hashCode in class HereReferencePart

Returns:

hash code for part

resolve

public java.lang.Object resolve(ReferenceResolver rr,
                                Reference r,
                                int index)
                         throws SmartFrogResolutionException

Resolves this reference part using the reference resolver. The originating reference and index are needed to enable request forwarding

Overrides:

resolve in class HereReferencePart

Parameters:

rr - reference resolver

r - reference which this part sits in

index - index of this reference part in r

Returns:

the attribute found on resolution

Throws:

SmartFrogResolutionException - if failed to resolve reference

resolve

public java.lang.Object resolve(RemoteReferenceResolver rr,
                                Reference r,
                                int index)
                         throws SmartFrogResolutionException

Resolves this reference part using the remote reference resolver. The originating reference and index are needed to enable request forwarding

Overrides:

resolve in class HereReferencePart

Parameters:

rr - reference resolver

r - reference which this part sits in

index - index of this reference part in r

Returns:

the attribute found on resolution

Throws:

SmartFrogResolutionException - if failed to resolve reference
