ByteQuadsCanonicalizer (jackson-core 2.8.6)

java.lang.Object
- com.fasterxml.jackson.core.sym.ByteQuadsCanonicalizer

```
public final class ByteQuadsCanonicalizer
extends Object
```
Replacement for BytesToNameCanonicalizer which aims at more localized memory access due to flattening of name quad data. Performance improvement modest for simple JSON document data binding (maybe 3%), but should help more for larger symbol tables, or for binary formats like Smile.

Since:

2.6

`int`	`calcHash(int q1, int q2)`
`int`	`calcHash(int q1, int q2, int q3)`
`static ByteQuadsCanonicalizer`	`createRoot()` Factory method to call to create a symbol table instance with a randomized seed value.
`protected static ByteQuadsCanonicalizer`	`createRoot(int seed)` Factory method that should only be called from unit tests, where seed value should remain the same.

`ByteQuadsCanonicalizer`	`makeChild(int flags)` Factory method used to create actual symbol table instance to use for parsing.
`boolean`	`maybeDirty()` Method called to check to quickly see if a child symbol table may have gotten additional entries.
`int`	`primaryCount()` Method mostly needed by unit tests; calculates number of entries that are in the primary slot set.
`void`	`release()` Method called by the using code to indicate it is done with this instance.
`int`	`secondaryCount()` Method mostly needed by unit tests; calculates number of entries in secondary buckets
`int`	`size()`
`int`	`spilloverCount()` Method mostly needed by unit tests; calculates number of entries in shared spillover area
`int`	`tertiaryCount()` Method mostly needed by unit tests; calculates number of entries in tertiary buckets

- Method Detail
  - createRoot
```
public static ByteQuadsCanonicalizer createRoot()
```
    Factory method to call to create a symbol table instance with a randomized seed value.
  - createRoot
```
protected static ByteQuadsCanonicalizer createRoot(int seed)
```
    Factory method that should only be called from unit tests, where seed value should remain the same.
  - makeChild
```
public ByteQuadsCanonicalizer makeChild(int flags)
```
    Factory method used to create actual symbol table instance to use for parsing.
  - release
```
public void release()
```
    Method called by the using code to indicate it is done with this instance. This lets instance merge accumulated changes into parent (if need be), safely and efficiently, and without calling code having to know about parent information
  - size
```
public int size()
```
  - bucketCount
```
public int bucketCount()
```
    Returns number of primary slots table has currently
  - maybeDirty
```
public boolean maybeDirty()
```
    Method called to check to quickly see if a child symbol table may have gotten additional entries. Used for checking to see if a child table should be merged into shared table.
  - hashSeed
```
public int hashSeed()
```
  - primaryCount
```
public int primaryCount()
```
    Method mostly needed by unit tests; calculates number of entries that are in the primary slot set. These are "perfect" entries, accessible with a single lookup
  - secondaryCount
```
public int secondaryCount()
```
    Method mostly needed by unit tests; calculates number of entries in secondary buckets
  - tertiaryCount
```
public int tertiaryCount()
```
    Method mostly needed by unit tests; calculates number of entries in tertiary buckets
  - spilloverCount
```
public int spilloverCount()
```
    Method mostly needed by unit tests; calculates number of entries in shared spillover area
  - totalCount
```
public int totalCount()
```
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - findName
```
public String findName(int q1)
```
  - findName
```
public String findName(int q1,
              int q2)
```
  - findName
```
public String findName(int q1,
              int q2,
              int q3)
```
  - findName
```
public String findName(int[] q,
              int qlen)
```
  - addName
```
public String addName(String name,
             int q1)
```
  - addName
```
public String addName(String name,
             int q1,
             int q2)
```
  - addName
```
public String addName(String name,
             int q1,
             int q2,
             int q3)
```
  - addName
```
public String addName(String name,
             int[] q,
             int qlen)
```
  - calcHash
```
public int calcHash(int q1)
```
  - calcHash
```
public int calcHash(int q1,
           int q2)
```
  - calcHash

           int q2,
           int q3)
```
  - calcHash
```
