      org.hd.d.pg2k.svrCore.ExhibitPropsComputableMutableVoteCache.CorrType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ExhibitPropsComputableMutableVoteCache.CorrType>

Enclosing class:

ExhibitPropsComputableMutableVoteCache

public static enum ExhibitPropsComputableMutableVoteCache.CorrType
extends java.lang.Enum<ExhibitPropsComputableMutableVoteCache.CorrType>

Correlation types. By default most correlation types/data is "dense", ie there should be many examples for and against each value.

Some types are "sparse", ie where we usually expect only one or two examples for a given value, and so we want to filter these more gently than usual.

VARIANT

public static final ExhibitPropsComputableMutableVoteCache.CorrType VARIANT

By variation on same exhibit (sparse).

SIMILAR

public static final ExhibitPropsComputableMutableVoteCache.CorrType SIMILAR

By similar exhibit (sparse).

SIZE

public static final ExhibitPropsComputableMutableVoteCache.CorrType SIZE

By exhibit size (bytes).

ATTRIBUTE

public static final ExhibitPropsComputableMutableVoteCache.CorrType ATTRIBUTE

By exhibit attribute word(s).

RESOLUTION

public static final ExhibitPropsComputableMutableVoteCache.CorrType RESOLUTION

By exhibit resolution (eg pixels).

MAIN_WORD

public static final ExhibitPropsComputableMutableVoteCache.CorrType MAIN_WORD

By exhibit main word.

CATEGORY

public static final ExhibitPropsComputableMutableVoteCache.CorrType CATEGORY

By exhibit category.

TYPE

public static final ExhibitPropsComputableMutableVoteCache.CorrType TYPE

By exhibit type.

AUTHOR

public static final ExhibitPropsComputableMutableVoteCache.CorrType AUTHOR

By author.

MIME1

public static final ExhibitPropsComputableMutableVoteCache.CorrType MIME1

By MIME primary type component.

PREFIX

public static final ExhibitPropsComputableMutableVoteCache.CorrType PREFIX

By prefixes.

STEM_WORDS

public static final ExhibitPropsComputableMutableVoteCache.CorrType STEM_WORDS

By all stem words.

sparse

private final boolean sparse

Is this correlation "sparse"?.

values

public static ExhibitPropsComputableMutableVoteCache.CorrType[] 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 (ExhibitPropsComputableMutableVoteCache.CorrType c : ExhibitPropsComputableMutableVoteCache.CorrType.values())
    System.out.println(c);

Returns:

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

valueOf

public static ExhibitPropsComputableMutableVoteCache.CorrType valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

isSparse

public final boolean isSparse()

Get the "sparseness" flag.

makeCacheKey

static void makeCacheKey(ExhibitPropsComputableMutableVoteCache.CorrType corrType,
                         ExhibitStaticAttr esa,
                         AllExhibitProperties aep,
                         java.util.Set<java.lang.String> result)
                  throws java.io.IOException

Make the appropriate cache lookup key(s) for a given value and full valid exhibit name; never null. Add zero-or-more, non-null, non-empty cache key(s) of the form: ENUM : value eg SIZE:16

Parameters:

corrType - the correlation type; never null

esa - exhibit details; never null

aep - never null

result - non-null, mutable Set to which result is added

Throws:

java.io.IOException - if key cannot be constructed

makeCacheKeys

static java.util.Set<java.lang.String> makeCacheKeys(ExhibitStaticAttr esa,
                                                     AllExhibitProperties aep)

Make all cache keys for a given exhibit; never null. This may return a variable number of keys, and may ignore those that cannot currently be made and are unlikely ever to be made, but is as consistent as possible for any one exhibit.

Returns:

non-null, possibly-empty, set of cache keys
