Constructor and Description
TFloatHash() Creates a new TFloatHash instance with the default capacity and load factor.
TFloatHash(int initialCapacity) Creates a new TFloatHash instance whose capacity is the next highest prime above initialCapacity + 1 unless that value is already prime.
TFloatHash(int initialCapacity, float loadFactor) Creates a new TFloatHash instance with a prime value at or near the specified capacity and load factor.
TFloatHash(int initialCapacity, float loadFactor, float no_entry_value) Creates a new TFloatHash instance with a prime value at or near the specified capacity and load factor.

Constructor Detail

TFloatHash

public TFloatHash()

Creates a new TFloatHash instance with the default capacity and load factor.

TFloatHash

public TFloatHash(int initialCapacity)

Creates a new TFloatHash instance whose capacity is the next highest prime above initialCapacity + 1 unless that value is already prime.

Parameters:

initialCapacity - an int value

TFloatHash

public TFloatHash(int initialCapacity,
                  float loadFactor)

Creates a new TFloatHash instance with a prime value at or near the specified capacity and load factor.

Parameters:

initialCapacity - used to find a prime capacity for the table.

loadFactor - used to calculate the threshold over which rehashing takes place.

TFloatHash

public TFloatHash(int initialCapacity,
                  float loadFactor,
                  float no_entry_value)

Creates a new TFloatHash instance with a prime value at or near the specified capacity and load factor.

Parameters:

initialCapacity - used to find a prime capacity for the table.

loadFactor - used to calculate the threshold over which rehashing takes place.

no_entry_value - value that represents null

Method Detail

getNoEntryValue

public float getNoEntryValue()

Returns the value that is used to represent null. The default value is generally zero, but can be changed during construction of the collection.

Returns:

the value that represents null

contains

public boolean contains(float val)

Searches the set for val

Parameters:

val - an float value

Returns:

a boolean value

forEach

public boolean forEach(TFloatProcedure procedure)

Executes procedure for each element in the set.

Parameters:

procedure - a TObjectProcedure value

Returns:

false if the loop over the set terminated because the procedure returned false for some value.
