All Implemented Interfaces:

SearchResultListener, java.io.Serializable

@ThreadSafety(level=NOT_THREADSAFE)
public final class LDAPSearch
extends LDAPCommandLineTool
implements SearchResultListener

This class provides a simple tool that can be used to search an LDAP directory server. Some of the APIs demonstrated by this example include:

• Argument Parsing (from the com.unboundid.util.args package)
• LDAP Command-Line Tool (from the com.unboundid.util package)
• LDAP Communication (from the com.unboundid.ldap.sdk package)

All of the necessary information is provided using command line arguments. Supported arguments include those allowed by the LDAPCommandLineTool class, as well as the following additional arguments:

• "-b {baseDN}" or "--baseDN {baseDN}" -- specifies the base DN to use for the search. This must be provided.
• "-s {scope}" or "--scope {scope}" -- specifies the scope to use for the search. The scope value should be one of "base", "one", "sub", or "subord". If this isn't specified, then a scope of "sub" will be used.
• "-R" or "--followReferrals" -- indicates that the tool should follow any referrals encountered while searching.
• "-t" or "--terse" -- indicates that the tool should generate minimal output beyond the search results.
• "-i {millis}" or "--repeatIntervalMillis {millis}" -- indicates that the search should be periodically repeated with the specified delay (in milliseconds) between requests.
• "-n {count}" or "--numSearches {count}" -- specifies the total number of times that the search should be performed. This may only be used in conjunction with the "--repeatIntervalMillis" argument. If "--repeatIntervalMillis" is used without "--numSearches", then the searches will continue to be repeated until the tool is interrupted.

In addition, after the above named arguments are provided, a set of one or more unnamed trailing arguments must be given. The first argument should be the string representation of the filter to use for the search. If there are any additional trailing arguments, then they will be interpreted as the attributes to return in matching entries. If no attribute names are given, then the server should return all user attributes in matching entries.

Note that this class implements the SearchResultListener interface, which will be notified whenever a search result entry or reference is returned from the server. Whenever an entry is received, it will simply be printed displayed in LDIF.

Constructor Detail

LDAPSearch

public LDAPSearch(java.io.OutputStream outStream,
                  java.io.OutputStream errStream)

Creates a new instance of this tool.

Parameters:

outStream - The output stream to which standard out should be written. It may be null if output should be suppressed.

errStream - The output stream to which standard error should be written. It may be null if error messages should be suppressed.

Method Detail

main

public static void main(java.lang.String[] args)

Parse the provided command line arguments and make the appropriate set of changes.

Parameters:

args - The command line arguments provided to this program.

main

public static ResultCode main(java.lang.String[] args,
                              java.io.OutputStream outStream,
                              java.io.OutputStream errStream)

Parse the provided command line arguments and make the appropriate set of changes.

Parameters:

args - The command line arguments provided to this program.

outStream - The output stream to which standard out should be written. It may be null if output should be suppressed.

errStream - The output stream to which standard error should be written. It may be null if error messages should be suppressed.

Returns:

A result code indicating whether the processing was successful.

getToolName

public java.lang.String getToolName()

Retrieves the name for this tool.

Specified by:

getToolName in class CommandLineTool

Returns:

The name for this tool.

getToolDescription

public java.lang.String getToolDescription()

Retrieves the description for this tool.

Specified by:

getToolDescription in class CommandLineTool

Returns:

The description for this tool.

getToolVersion

public java.lang.String getToolVersion()

Retrieves the version string for this tool.

Overrides:

getToolVersion in class CommandLineTool

Returns:

The version string for this tool.

getMaxTrailingArguments

public int getMaxTrailingArguments()

Retrieves the maximum number of unnamed trailing arguments that are allowed.

Overrides:

getMaxTrailingArguments in class CommandLineTool

Returns:

A negative value to indicate that any number of trailing arguments may be provided.
