Member Function Documentation

◆ AddItem()

bool ON_Hash32Table::AddItem ( ON__UINT32  hash32,
class ON_Hash32TableItem item 
)

Description: Adds an item to the hash table. Parameters: hash32 - [in] item - [in/out] Returns: The added item.

◆ FirstItemWithHash()

class ON_Hash32TableItem* ON_Hash32Table::FirstItemWithHash ( ON__UINT32  hash32) const

Returns: The first item in the hash table with hash = hash32. Parameters: hash32 - [in] Remarks: This function is used to find the first element in the hash table with the specified hash32 falue. Use ON_Hash32TableItem.NextItemWithSameHash() to get the next item in the has table with the same hash value.

◆ FirstTableItem()

class ON_Hash32TableItem* ON_Hash32Table::FirstTableItem ( ) const

Returns: The first item in the hash table. Remarks: This function is used for iterating throught every element in the hash table.

◆ HashTableSerialNumber()

ON__UINT32 ON_Hash32Table::HashTableSerialNumber ( ) const

◆ IsValid()

bool ON_Hash32Table::IsValid ( ) const

◆ ItemCount()

unsigned int ON_Hash32Table::ItemCount ( ) const

Returns: Number of items in the hash table

◆ NextItemWithHash()

class ON_Hash32TableItem* ON_Hash32Table::NextItemWithHash ( const class ON_Hash32TableItem current_item) const

◆ NextTableItem()

class ON_Hash32TableItem* ON_Hash32Table::NextTableItem ( const ON_Hash32TableItem item) const

Returns: The next item in the hash table. Remarks: This function is used for iterating throught every element in the hash table.

◆ RemoveAllItems() [1/2]

unsigned int ON_Hash32Table::RemoveAllItems ( )

Description: Removes all hash table items. Caller is responsible for managing the item memory.

◆ RemoveAllItems() [2/2]

unsigned int ON_Hash32Table::RemoveAllItems ( class ON_FixedSizePool fsp)

Description: Removes all hash table items. For each item memset(item,0,fsp.SizeofElement()) and fsp.ReturnElement(item) are called.

◆ RemoveItem()

bool ON_Hash32Table::RemoveItem ( class ON_Hash32TableItem item)

Description: Remove an item from the hash table. Caller is responsible for managing item memory. Parameters: item - [in/out] If the item is removed, the has table serial number is set to zero. Returns: The true if the item was removed.
