Ref
A symbolic reference does not have its own ObjectId value, but
instead points to another Ref in the same database and always
uses that other reference's value as its own.
isSymbolic in interface Refpublic Ref getLeaf()
RefRef.isSymbolic() is false.
If Ref.isSymbolic() is false, returns this.
If Ref.isSymbolic() is true, this method recursively traverses
Ref.getTarget() until Ref.isSymbolic() returns false.
This method is effectively
return isSymbolic() ? getTarget().getLeaf() : this;
public Ref getTarget()
Refthis.
If Ref.isSymbolic() is true this method returns the reference it
directly names, which might not be the leaf reference, but could be
another symbolic reference.
If this is a leaf level reference that contains its own ObjectId,this
method returns this.
