Enum Constant Detail

SingleThreaded

public static final SrvMonDisruptorClaimStrategy SingleThreaded

Optimised strategy to be used when there is a single publisher thread claiming sequences.

MultiThreaded

public static final SrvMonDisruptorClaimStrategy MultiThreaded

Strategy to be used when there are multiple publisher threads claiming sequences.

Strategy to be used when there are multiple publisher threads claiming sequences. This strategy is reasonably forgiving when the multiple publisher threads are highly contended or working in an environment where there is insufficient CPUs to handle multiple publisher threads.

MultiThreadedSufficientCores

public static final SrvMonDisruptorClaimStrategy MultiThreadedSufficientCores

Strategy to be used when there are multiple publisher threads claiming sequences.

This strategy requires sufficient cores to allow multiple publishers to be concurrently claiming sequences and those thread a contented relatively infrequently.

Unknown

public static final SrvMonDisruptorClaimStrategy Unknown

Indicates the claim strategy in use is invalid or not recognized.

Field Detail

VALUES

public static final List<SrvMonDisruptorClaimStrategy> VALUES

A zero garbage alternative to values().

EMPTY_ARRAY

public static final SrvMonDisruptorClaimStrategy[] EMPTY_ARRAY

A preallocated empty array used to avoid garbage when returning empty arrays.

val

public final int val

The ordinal value

Method Detail

values

public static SrvMonDisruptorClaimStrategy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SrvMonDisruptorClaimStrategy c : SrvMonDisruptorClaimStrategy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SrvMonDisruptorClaimStrategy valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

hasValue

public static final boolean hasValue(int val)

Tests if the passed in value represents a 'constant' in this enumeration.

Parameters:

val - The value to test for.

Returns:

true If this enumeration has the given 'constant' value.

nameASCIILen

public static final int nameASCIILen(SrvMonDisruptorClaimStrategy val)

Get an enum's name's length serialized using ASCII encoding

Parameters:

val - The enum whose name to serialize.

Returns:

The serialized length

nameTo

public static final int nameTo(SrvMonDisruptorClaimStrategy val,
                               long addr,
                               int offset)

Serialize an enum's name to a native memory region

Parameters:

val - The enum whose name to serialize.

addr - The native address to serialize to

offset - The offset relative to the native address to serialize to

Returns:

The serialized length

fromName

public static final SrvMonDisruptorClaimStrategy fromName(long addr,
                                                          int offset,
                                                          int limit,
                                                          char delim,
                                                          IOBuffer.ParsedCount parsedCount)

Gets an enum from its serialized name value

Parameters:

val - The value whose name to serialize.

addr - The native address where the enum's name is serialized

offset - The offset relative to the native address where the name is serialized

limit - The limit into the buffer to parse

delim - The terminating character of the serialized name

parsedCount - Contains the number of characters parsed

Returns:

The deserialized enum

fromValue

public static final SrvMonDisruptorClaimStrategy fromValue(int val)

Get an enum from its value.

Parameters:

val - The value to look up.

Returns:

The value corresponding to the constant value

Throws:

IllegalArgumentException - if the provided code is not a valid code for this enum

fromCode

public static final SrvMonDisruptorClaimStrategy fromCode(int code)

Get an enum from its 'code' value.

Parameters:

code - The 'code' value to look up.

Returns:

The enumeration value corresponding to the 'code' value

Throws:

IllegalArgumentException - if the provided code is not a valid code for this enum

fromCodeString

public static final SrvMonDisruptorClaimStrategy fromCodeString(String value)

Get an enum from its 'code' value in string form.

Parameters:

value - The 'code' value to look up.

Returns:

The enumeration value corresponding to the 'code' value

Throws:

IllegalArgumentException - if the provided code is not a valid code for this enum

getCodeType

public static final Class<?> getCodeType()

Gets the code type with which this enumeration was generated.

Returns:

The code type (Character.class, Integer.class, or String.class)

getCodeString

public final String getCodeString()

Gets the code value for this enumeration as a String.

Returns:

the code value for this enumeration as a String.
