public class RpcPropertyDefs
extends Object

A convenience class used to hold all publicly-visible properties keys used by the RPC implementation.

The intention here is to simply centralize property key names so end users have some idea what's available and what each key's semantics are. This is NOT intended as a full property repository -- property management is generally up to individual classes and packages.

Note that in general, all properties can have an optional short form ("NICK", Anglo-English for nickname...) which is typically just the full form without the cumbersome com.perforce.whatever prefix; use of the short form is particularly convenient for passing in properties through the url mechanism, but you have to be very careful that there are no conflicting system or environmental properties...

Note that if you add a property somewhere that's likely to be useful to end users, you should use the mechanism here to document it.

public static final int RPC_DEFAULT_SEND_BYTE_BUF_SIZE

RPC_SOCKET_PERFORMANCE_PREFERENCES_DEFAULT

public static final int[] RPC_SOCKET_PERFORMANCE_PREFERENCES_DEFAULT

Default socket performance preferences are described by three integers whose values indicate the relative importance of short connection time, low latency, and high bandwidth.

RPC_SOCKET_PERFORMANCE_PREFERENCES_NICK

public static final String RPC_SOCKET_PERFORMANCE_PREFERENCES_NICK

If this property is set, attempt to set the underlying RPC socket's performance preferences to the associated values, in integers, delimited by commas. Note that you must specify exactly three integers, otherwise this property will be ignored.

The absolute values of the integers are irrelevant; in order to choose a protocol the values are simply compared, with larger values indicating stronger preferences. Negative values represent a lower priority than positive values.

If the application prefers short connection time over both low latency and high bandwidth, for example, then it could invoke this method with the values (1, 0, 0). If the application prefers high bandwidth above low latency, and low latency above short connection time, then it could invoke this method with the values (0, 1, 2).

getProperty

public static String getProperty(Properties props,
                                 String nick)

Convenience method to first try to get the short form from the passed-in properties, then try for the long form. Returns null if it can't find a definition associated with either short or long form keys.

Note: this method is null safe, i.e. if either or both props or nick is null, it simply returns null.

getProperty

public static String getProperty(Properties props,
                                 String nick,
                                 String defaultValue)

Convenience method to first try to get the short form from the passed-in properties, then try for the long form. Returns defaultValue if it can't find a definition associated with either short or long form keys.

Note: this method is null safe, i.e. if either or both props or nick is null, it simply returns null.

getPropertyAsInt

public static int getPropertyAsInt(Properties props,
                                   String nick,
                                   int defaultValue)

Return a named property as an int, if possible. Defaults to defaultValue if the property wasn't found under first its short form, then its long form, or if the resulting attempt to convert to an integer was unsuccessful.

Will log to P4JLog any conversion error as a warning.

Note: this method is null safe, i.e. if either or both props or nick is null, it simply returns defaultValue.

getPropertyAsIntArray

public static int[] getPropertyAsIntArray(Properties props,
                                          String nick,

                                          int[] defaultValues)

Return a named property as an int array, if possible. The property value is split into values by a specified delimiter (if null, a default delimiter will be used). Return an empty int array if the property wasn't found under first its short form, then its long form, or if the resulting attempt to convert to an integer was unsuccessful.

Will log to P4JLog any conversion error as a warning.

Note: this method is null safe, i.e. if either or both props or nick is null, it simply returns an empty int array.

getPropertyAsBoolean

public static boolean getPropertyAsBoolean(Properties props,

Return a named property a boolean, if possible. Defaults to defaultValue if the property wasn't found under first its short form, then its long form, or if the resulting attempt to convert to an integer was unsuccessful.

Will log to P4JLog any conversion error as a warning.

Note: this method is null safe, i.e. if either or both props or nick is null, it simply returns defaultValue.
