PipelineKey_old

public non-sealed class KeyBuilder
extends Key

Used to build a packed array as the storage or lookup key of a hash map.

Note: A flush() is expected at the end of key building.

Method Details

clear

public final void clear()

Resets this key builder to initial state.

size

public final int size()

Overrides:

size in class Key

Returns:

the number of ints

isEmpty

public final boolean isEmpty()

Overrides:

isEmpty in class Key

Returns:

true if this key builder contains no bits

addBits

public void addBits(int numBits,
 int value,
 String label)

addBool

public final void addBool(boolean b,
 String label)

addInt32

public final void addInt32(int v,
 String label)

addInt

public final void addInt(int v)

Makes a word-boundary and adds a full word.

addInts

public final void addInts(int[] v,
 int off,
 int len)

Makes a word-boundary and adds an array of words.

flush

public final void flush()

Introduces a word-boundary in the key. Must be called before using the key with any cache, but can also be called to create a break between generic data and backend-specific data.

trim

public final void trim()

Trims the backing store so that the capacity is equal to the size.

toStorageKey

public final Key toStorageKey()

Returns:

a copy of packed int array as storage key

hashCode

public final int hashCode()

Same as Arrays.hashCode(int[]).

Overrides:

hashCode in class Key

equals

public final boolean equals(Object o)

Compares with packed int array (storage key).

Overrides:

equals in class Key
