Constructor Detail

HttpGetSrcNode

public HttpGetSrcNode(DasDirNode parent,
                      java.lang.String name,
                      java.util.List<java.lang.String> locations)

Method Detail

type

public java.lang.String type()

Description copied from interface: DasNode

Get the node type.

Specified by:

type in interface DasNode

Returns:

A string representing the node type

isSrc

public boolean isSrc()

Description copied from interface: DasNode

Can this catalog node provide data

Specified by:

isSrc in interface DasNode

Returns:

true if this node describes one or more data sources

isDir

public boolean isDir()

Description copied from interface: DasNode

Can this catalog node have the sub-nodes?

Specified by:

isDir in interface DasNode

Returns:

true if this node can have child nodes, not that it necessarily contains any.

isInfo

public boolean isInfo()

Description copied from interface: DasNode

Is this object an information node.

Specified by:

isInfo in interface DasNode

Returns:

true if this node in the catalog provides a description of a mission, spacecraft, instrument, person or any other item category

queryVerify

public boolean queryVerify(java.util.Map<java.lang.String,java.lang.String> dQuery)

Description copied from interface: DasSrcNode

Determine if the given list of query parameters are valid

Specified by:

queryVerify in interface DasSrcNode

Returns:

True if this set of parameters is valid, false otherwise

name

public java.lang.String name()

Description copied from interface: DasNode

get the node name

Specified by:

name in interface DasNode

Returns:

The human readable name of the node, not it's path ID

path

public java.lang.String path()

Description copied from interface: DasNode

get the node path

Specified by:

path in interface DasNode

Returns:

The catalog path to this node. For root nodes this is null

toString

public java.lang.String toString()

Description copied from interface: DasNode

A summary of the node

Specified by:

toString in interface DasNode

Overrides:

toString in class java.lang.Object

Returns:

A short string describing the node, not an info dump of the contents

prettyPrintLoc

public java.lang.String prettyPrintLoc(java.lang.String sPre,
                                       java.lang.String sSep)

Get the root node list as a string with some separator and prefix

Parameters:

sPre - A prefix to place before each root node URL, may be null

sSep - The separator to use between each root node URL, may be null

Returns:

A formatted string containing a list of all root node URLs

isRoot

public boolean isRoot()

Description copied from interface: DasNode

Is this object a detached root of a catalog tree. Note that the build in root URLs are always detached roots because there is no higher node to find. A detached source or info node can still be a root node without also being a directory.

Specified by:

isRoot in interface DasNode

Returns:

true if no higher node is reachable from this one.

getRoot

public DasNode getRoot()

Description copied from interface: DasNode

Return the highest node reachable by this catalog node.

Specified by:

getRoot in interface DasNode

Returns:

the highest node reachable by this catalog node, which may just be itself.
