org.thales.punch.libraries.punchlang.api.IResourceBuilder.CompactionType

All Implemented Interfaces:

Serializable, Comparable<IResourceBuilder.CompactionType>

Enclosing interface:

IResourceBuilder

public static enum IResourceBuilder.CompactionType
extends Enum<IResourceBuilder.CompactionType>

very large resource files are common. The caller can provide a hint to indicate a more compact strategy to keep in memory billions of JSON objects.

Enum Constant Detail

NONE

public static final IResourceBuilder.CompactionType NONE

No compaction. This is the most CPU efficient but takes a *lot* of memory. Do not use for resource files larger than 10Mbs.

STRING

public static final IResourceBuilder.CompactionType STRING

Inner tuples are kept as JSON strings. This drastically reduce the number of objects in memory. It also make it possible to have various encoding not only UTF_8.

Prefer the bytebuf below much more efficient.

BYTEBUF

public static final IResourceBuilder.CompactionType BYTEBUF

Stores all json inner documents in a contiguous bytebuf. This leverages direc allocated buffer, and is the most memory efficient.

INPLACE

public static final IResourceBuilder.CompactionType INPLACE

Similar to the STRING optimisation but the update of newly loaded values is Update the

Method Detail

values

public static IResourceBuilder.CompactionType[] 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 (IResourceBuilder.CompactionType c : IResourceBuilder.CompactionType.values())
    System.out.println(c);

Returns:

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

valueOf

public static IResourceBuilder.CompactionType 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
