TakeIfExists Method (template, timeout)

Take any matching object from the space, returning null if there currently is none. Equivalent to take, except that blocking is done only if necessary to wait for transactional state to settle.

Declaration Syntax

Visual Basic

Visual C++

T TakeIfExists<T>(
	T template,
	long timeout
)

Function TakeIfExists(Of T) ( _
	template As T, _
	timeout As Long _
) As T

generic<typename T>
T TakeIfExists(
	T template, 
	long long timeout

J# supports the use of generic APIs, but not the declaration of new ones.

Generic Template Parameters

T: Type of object to read.

Parameters

template (T): The template used for matching.

timeout (Int64): How long the client is willing to wait for a transactionally proper matching object.

Return Value

The object taken from the space (null if no match was found).

Exceptions

Exception	Condition
UnusableEntryException	A serialized field of the object being read cannot be deserialized.
