Member Function Documentation

◆ capacity()

int com.jogamp.common.util.IntIntHashMap.capacity ( )

Returns the current capacity (buckets) in this map.

Definition at line 331 of file IntIntHashMap.java.

◆ clear()

void com.jogamp.common.util.IntIntHashMap.clear ( )

Clears the entire map.

The size is 0 after this operation.

Definition at line 338 of file IntIntHashMap.java.

◆ clone()

Object com.jogamp.common.util.IntIntHashMap.clone ( )

Disclaimer: If the value type doesn't implement clone(), only the reference is copied.

Note: Due to private fields we cannot implement a copy constructor, sorry.

Parameters
sourcethe primitive hash map to copy

Here is the caller graph for this function:

◆ get()

int com.jogamp.common.util.IntIntHashMap.get ( final int  key)

Returns the value to which the specified key is mapped, or getKeyNotFoundValue if this map contains no mapping for the key.

Definition at line 226 of file IntIntHashMap.java.

◆ getKeyNotFoundValue()

int com.jogamp.common.util.IntIntHashMap.getKeyNotFoundValue ( )

Returns the value which is returned if no value has been found for the specified key.

Here is the caller graph for this function:

◆ iterator()

Iterator< Entry > com.jogamp.common.util.IntIntHashMap.iterator ( )

Returns a new Iterator.

Note: this Iterator does not yet support removal of elements.

Definition at line 348 of file IntIntHashMap.java.

Here is the caller graph for this function:

◆ put()

int com.jogamp.common.util.IntIntHashMap.put ( final int  key,
final int  value 
)

Maps the key to the specified value.

If a mapping to this key already exists, the previous value will be returned (otherwise getKeyNotFoundValue).

Definition at line 242 of file IntIntHashMap.java.

Here is the caller graph for this function:

◆ putAll()

void com.jogamp.common.util.IntIntHashMap.putAll ( final IntIntHashMap  source)

Copies all of the mappings from the specified map to this map.

Definition at line 285 of file IntIntHashMap.java.

Here is the call graph for this function:

◆ remove()

int com.jogamp.common.util.IntIntHashMap.remove ( final int  key)

Removes the key-value mapping from this map.

Returns the previously mapped value or getKeyNotFoundValue if no such mapping exists.

Definition at line 298 of file IntIntHashMap.java.

Here is the caller graph for this function:

◆ setKeyNotFoundValue()

int com.jogamp.common.util.IntIntHashMap.setKeyNotFoundValue ( final int  newKeyNotFoundValue)

Sets the new key not found value.

For primitive types (int, long) the default is -1, for Object types, the default is null.

Returns
the previous key not found value

Here is the caller graph for this function:

◆ size()

int com.jogamp.common.util.IntIntHashMap.size ( )

Returns the current number of key-value mappings in this map.

Definition at line 324 of file IntIntHashMap.java.

◆ toString() [1/2]

String com.jogamp.common.util.IntIntHashMap.toString ( )

Definition at line 397 of file IntIntHashMap.java.

◆ toString() [2/2]

StringBuilder com.jogamp.common.util.IntIntHashMap.toString ( StringBuilder  sb)
Parameters
sbif null, a new StringBuilder is created
Returns
StringBuilder instance with appended string information of this Entry
