Constructor Detail

J4pClientBuilder

public J4pClientBuilder()

Package access constructor, use static method on J4pClient for creating the builder.

Method Detail

url

public final J4pClientBuilder url(String pUrl)

The Agent URL to connect to

Parameters:

pUrl - agent URL

user

public final J4pClientBuilder user(String pUser)

User to use for authentication

Parameters:

pUser - user name

password

public final J4pClientBuilder password(String pPassword)

Password for authentication

Parameters:

pPassword - password to use

target

public final J4pClientBuilder target(String pUrl)

Target service URL when using the agent as a JSR-160 proxy

Parameters:

pUrl - JMX service URL for the 'real' target (that gets contacted by the agent)

targetUser

public final J4pClientBuilder targetUser(String pUser)

Target user for proxy mode. This parameter takes only effect when a target is set.

Parameters:

pUser - User to be used for authentication in JSR-160 proxy communication

targetPassword

public final J4pClientBuilder targetPassword(String pPassword)

Target password for proxy mode. This parameter takes only effect when a target is set and the target user is not null

Parameters:

pPassword - Password to be used for authentication in JSR-160 proxy communication

singleConnection

public final J4pClientBuilder singleConnection()

Use a single threaded client for connecting to the agent. This is not very suitable in multithreaded environments

pooledConnections

public final J4pClientBuilder pooledConnections()

Use a pooled connection manager for connecting to the agent, which uses a pool of connections (see and {@link #maxConnectionPoolTimeout(int)} for tuning the pool

connectionTimeout

public final J4pClientBuilder connectionTimeout(int pTimeOut)

Determines the timeout in milliseconds until a connection is established. A timeout value of zero is interpreted as an infinite timeout. Default is 20 seconds.

Parameters:

pTimeOut - timeout in milliseconds

socketTimeout

public final J4pClientBuilder socketTimeout(int pTimeOut)

Defines the socket timeout (SO_TIMEOUT) in milliseconds, which is the timeout for waiting for data or, put differently, a maximum period inactivity between two consecutive data packets). A timeout value of zero is interpreted as an infinite timeout, a negative value means the system default.

Parameters:

pTimeOut - SO_TIMEOUT value in milliseconds, 0 mean no timeout at all.

maxTotalConnections

public final J4pClientBuilder maxTotalConnections(int pConnections)

Sets the maximum number of connections allowed when using pooledConnections().

Parameters:

pConnections - number of max. simultaneous connections.

maxConnectionPoolTimeout

public final J4pClientBuilder maxConnectionPoolTimeout(int pConnectionPoolTimeout)

Sets the timeout in milliseconds used when retrieving a connection from the connection manager. Default is 500ms, if set to -1 the system default is used. Use 0 for an infinite timeout.

Parameters:

pConnectionPoolTimeout - timeout in milliseconds

contentCharset

public final J4pClientBuilder contentCharset(String pContentCharset)

Defines the charset to be used per default for encoding content body.

Parameters:

pContentCharset - the charset to use

contentCharset

public final J4pClientBuilder contentCharset(Charset pContentCharset)

Defines the charset to be used per default for encoding content body.

Parameters:

pContentCharset - the charset to use

expectContinue

public final J4pClientBuilder expectContinue(boolean pUse)

Activates 'Expect: 100-Continue' handshake for the entity enclosing methods. The purpose of the 'Expect: 100-Continue' handshake to allow a client that is sending a request message with a request body to determine if the origin server is willing to accept the request (based on the request headers) before the client sends the request body. The use of the 'Expect: 100-continue' handshake can result in noticable peformance improvement for entity enclosing requests that require the target server's authentication.

Parameters:

pUse - whether to use this algorithm or not

tcpNoDelay

public final J4pClientBuilder tcpNoDelay(boolean pUse)

Determines whether Nagle's algorithm is to be used. The Nagle's algorithm tries to conserve bandwidth by minimizing the number of segments that are sent. When applications wish to decrease network latency and increase performance, they can disable Nagle's algorithm (that is enable TCP_NODELAY). Data will be sent earlier, at the cost of an increase in bandwidth consumption.

Parameters:

pUse - whether to use NO_DELAY or not

socketBufferSize

public final J4pClientBuilder socketBufferSize(int pSize)

Determines the size of the internal socket buffer used to buffer data while receiving / transmitting HTTP messages.

Parameters:

pSize - size of socket buffer

cookieStore

public final J4pClientBuilder cookieStore(org.apache.http.client.CookieStore pCookieStore)

Use the given cookie store. This useful is some form baed authentication had to be performed.

Parameters:

pCookieStore - cookiestore containing the cookies to send for requests.

authenticator

public final J4pClientBuilder authenticator(J4pAuthenticator pAuthenticator)

Set the authenticator for this client

Parameters:

pAuthenticator - authenticator used for checking the given user and password (if any).

build

public J4pClient build()

Build the agent with the information given before

Returns:

a new J4pClient

createHttpClient

public org.apache.http.client.HttpClient createHttpClient()
