| Field Summary | |
| final public static int | LIST
Denotes a list component. | | final public static int | SCALAR
Denotes a scalar component, which is always a leaf. |
| Constructor Summary | |
| public | Value()
Default ctor. |
| Method Summary | |
| abstract public Object | clone()
Creates and returns a copy of this object. | | abstract public boolean | containsLFN(String filename, int linkage)
Determines if the Value contains an LFN of the specified linkage.
The logic uses short-circuit evaluation, thus finding things is
faster than not finding things. | | abstract public java.util.List | getAllLFN(int linkage)
Determines all LFN instances of a given scalar that match the
specified linkage. | | abstract public int | getContainerType()
This method determines which container is being used in the abstract
base class in order to avoid typeof constructs. | | abstract public java.util.List | getLFNList(int linkage)
Determines all LFN instances of a given scalar that match the
specified linkage. | | public String | getName()
Accessor method. | | abstract public String | getSymbolicType()
This method determines which container is being used in the abstract
base class in order to kludgy statements when printing debug info. | | public static boolean | isInRange(int x)
Predicate function to determine, if a container type is within
the legal range of values. | | public void | setName(String name)
Accessor method. |
| Value | | public Value()(Code) | | Default ctor.

| clone | | abstract public Object clone()(Code) | | Creates and returns a copy of this object.
a new instance. |
| containsLFN | | abstract public boolean containsLFN(String filename, int linkage)(Code) | | Determines if the Value contains an LFN of the specified linkage.
The logic uses short-circuit evaluation, thus finding things is
faster than not finding things. Searching a list is a potentially
expensive method.
Parameters:
filename - is the name of the LFN
Parameters:
linkage - is the linkage to check for, -1 for any linkage type. true if the LFN is contained in the scalar, false otherwise.

| getAllLFN | | abstract public java.util.List getAllLFN(int linkage)(Code) | | Determines all LFN instances of a given scalar that match the
specified linkage. This is a higher-level method employing the
given API.
Parameters:
linkage - is the linkage to check for, -1 for all filenames. a set of logical filename instances that match the linkageand were part of the scalar. The result may be an empty set, if nosuch result were to be found.

| getLFNList | | abstract public java.util.List getLFNList(int linkage)(Code) | | Determines all LFN instances of a given scalar that match the
specified linkage. This is a higher-level method employing the
given API. Note that also linkage of NONE will not be found in
wildcard search mode.
Parameters:
linkage - is the linkage to check for, -1 for all filenames. a set of all logical filenames that match the linkage andwere part of the scalar. The result may be an empty set, if no suchresult were to be found. For a linkage of -1, complete LFNs will bereturned, for any other linkage, just the filename will bereturned.

the symblic identifier for the type of the Value. |
| isInRange | | public static boolean isInRange(int x)(Code) | | Predicate function to determine, if a container type is within
the legal range of values.
Parameters:
x - is the container type true, if the type is within the legal range, orfalse, if the container type is outside legal range.

| setName | | public void setName(String name)(Code) | | Accessor method. Sets the attribute of same name to a new value.
Parameters:
name - is the new value to overwrite the current state with.
