Constructor Detail

SearchRequestImpl

public SearchRequestImpl(int id)
Creates a Lockable SearcRequest implementing object used to search the DIT.

Parameters:
id - the sequential message identifier
Method Detail

getAttributes

public java.util.Collection getAttributes()
Gets a list of the attributes to be returned from each entry which matches the search filter. There are two special values which may be used: an empty list with no attributes, and the attribute description string "*". Both of these signify that all user attributes are to be returned. (The "*" allows the client to request all user attributes in addition to specific operational attributes). Attributes MUST be named at most once in the list, and are returned at most once in an entry. If there are attribute descriptions in the list which are not recognized, they are ignored by the server. If the client does not want any attributes returned, it can specify a list containing only the attribute with OID "1.1". This OID was chosen arbitrarily and does not correspond to any attribute in use. Client implementors should note that even if all user attributes are requested, some attributes of the entry may not be included in search results due to access control or other restrictions. Furthermore, servers will not return operational attributes, such as objectClasses or attributeTypes, unless they are listed by name, since there may be extremely large number of values for certain operational attributes.

Specified by:
getAttributes in interface SearchRequest
Returns:
the collection of attributes to return for each entry

getBase

public java.lang.String getBase()
Gets the search base as a distinguished name.

Specified by:
getBase in interface SearchRequest
Returns:
the search base

setBase

public void setBase(java.lang.String base)
Sets the search base as a distinguished name.

Specified by:
setBase in interface SearchRequest
Parameters:
base - the search base

getDerefAliases

public DerefAliasesEnum getDerefAliases()
Gets the alias handling parameter.

Specified by:
getDerefAliases in interface SearchRequest
Returns:
the alias handling parameter enumeration.

setDerefAliases

public void setDerefAliases(DerefAliasesEnum derefAliases)
Sets the alias handling parameter.

Specified by:
setDerefAliases in interface SearchRequest
Parameters:
derefAliases - the alias handling parameter enumeration.

getFilter

public ExprNode getFilter()
Gets the search filter associated with this search request.

Specified by:
getFilter in interface SearchRequest
Returns:
the expression node for the root of the filter expression tree.

setFilter

public void setFilter(ExprNode filter)
Sets the search filter associated with this search request.

Specified by:
setFilter in interface SearchRequest
Parameters:
filter - the expression node for the root of the filter expression tree.

getResponseTypes

public MessageTypeEnum[] getResponseTypes()
Gets the different response types generated by a search request.

Specified by:
getResponseTypes in interface SearchRequest
Returns:
the RESPONSE_TYPES array
See Also:
RESPONSE_TYPES

getScope

public ScopeEnum getScope()
Gets the search scope parameter enumeration.

Specified by:
getScope in interface SearchRequest
Returns:
the scope enumeration parameter.

setScope

public void setScope(ScopeEnum scope)
Sets the search scope parameter enumeration.

Specified by:
setScope in interface SearchRequest
Parameters:
scope - the scope enumeration parameter.

getSizeLimit

public int getSizeLimit()
A sizelimit that restricts the maximum number of entries to be returned as a result of the search. A value of 0 in this field indicates that no client-requested sizelimit restrictions are in effect for the search. Servers may enforce a maximum number of entries to return.

Specified by:
getSizeLimit in interface SearchRequest
Returns:
search size limit.

setSizeLimit

public void setSizeLimit(int entriesMax)
Sets sizelimit that restricts the maximum number of entries to be returned as a result of the search. A value of 0 in this field indicates that no client-requested sizelimit restrictions are in effect for the search. Servers may enforce a maximum number of entries to return.

Specified by:
setSizeLimit in interface SearchRequest
Parameters:
entriesMax - maximum search result entries to return.

getTimeLimit

public int getTimeLimit()
Gets the timelimit that restricts the maximum time (in seconds) allowed for a search. A value of 0 in this field indicates that no client- requested timelimit restrictions are in effect for the search.

Specified by:
getTimeLimit in interface SearchRequest
Returns:
the search time limit in seconds.

setTimeLimit

public void setTimeLimit(int secondsMax)
Sets the timelimit that restricts the maximum time (in seconds) allowed for a search. A value of 0 in this field indicates that no client- requested timelimit restrictions are in effect for the search.

Specified by:
setTimeLimit in interface SearchRequest
Parameters:
secondsMax - the search time limit in seconds.

getTypesOnly

public boolean getTypesOnly()
An indicator as to whether search results will contain both attribute types and values, or just attribute types. Setting this field to TRUE causes only attribute types (no values) to be returned. Setting this field to FALSE causes both attribute types and values to be returned.

Specified by:
getTypesOnly in interface SearchRequest
Returns:
true for only types, false for types and values.

setTypesOnly

public void setTypesOnly(boolean typesOnly)
An indicator as to whether search results will contain both attribute types and values, or just attribute types. Setting this field to TRUE causes only attribute types (no values) to be returned. Setting this field to FALSE causes both attribute types and values to be returned.

Specified by:
setTypesOnly in interface SearchRequest
Parameters:
typesOnly - true for only types, false for types and values.

addAttribute

public void addAttribute(java.lang.String attribute)
Adds an attribute to the set of entry attributes to return.

Specified by:
addAttribute in interface SearchRequest
Parameters:
attribute - the attribute description or identifier.

removeAttribute

public void removeAttribute(java.lang.String attribute)
Removes an attribute to the set of entry attributes to return.

Specified by:
removeAttribute in interface SearchRequest
Parameters:
attribute - the attribute description or identifier.

getResultResponse

public ResultResponse getResultResponse()
The result containing response for this request.

Specified by:
getResultResponse in interface ResultResponseRequest
Returns:
the result containing response for this request

equals

public boolean equals(java.lang.Object obj)
Checks to see if two search requests are equal. The Lockable properties and the get/set context specific parameters are not consulted to determine equality. The filter expression tree comparison will normalize the child order of filter branch nodes then generate a string representation which is comparable. For the time being this is a very costly operation.

Overrides:
equals in class AbstractMessage
Parameters:
obj - the object to check for equality to this SearchRequest
Returns:
true if the obj is a SearchRequest and equals this SearchRequest, false otherwise

toString

public java.lang.String toString()
Return a string the represent a SearchRequest
