Read Method (query, tx, timeout)

Read any matching object from the space, blocking until one exists. Return null if the timeout expires.

Declaration Syntax

Visual Basic

Visual C++

T Read<T>(
	IQuery<T> query,
	ITransaction tx,
	long timeout
)

Function Read(Of T) ( _
	query As IQuery(Of T), _
	tx As ITransaction, _
	timeout As Long _
) As T

generic<typename T>
T Read(
	IQuery<T>^ query, 
	ITransaction^ tx, 
	long long timeout
)

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

Generic Template Parameters

Parameters

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