Constructor Detail

FVectorContainer64

public FVectorContainer64(java.lang.Class<T> type)

Creates an empty container that holds sequences of the specified type.

Parameters:

type - The specified Class<T> type.

FVectorContainer64

public FVectorContainer64(java.lang.Class<T> type,
                  java.lang.String fileName,
                  FileMode mode)

Constructs a FVectorContainer64 instance using the specified file.

Parameters:

type - The specified Class<T> type.

fileName - The specified file.

mode - A FileMode constant (Open or Create) that determines how to open or create the file.

Throws:

java.lang.RuntimeException - When the specified mode is different than Open or Create.

Remarks: The container is persistent (saved on the hard drive) and always call Close() method to flush the buffers.

Method Detail

Close

public void Close()

Closes the file and releases any resources associated with the current buffered stream.

Dispose

public void Dispose()

Closes the file and releases any resources associated with the current buffered stream.

NewVector

public FVector64<T> NewVector()

Creates an empty vector.

Returns:

An empty vector.

NewVector

public FVector64<T> NewVector(long n,
                     T item)

Creates a vector and initializes it with the specified value.

Parameters:

n - The number of copies of an element being inserted into the sequence.

item - The value of the element being inserted into the sequence.

Returns:

A new vector initialized with the specified value.

Remove

public boolean Remove(FVector64<T> list)

Removes the specified object from the container.

Parameters:

list - The object to remove from the container.

Returns:

True if item is successfully removed; otherwise, false. This method also returns false if item was not found in the sequence.

Size

public long Size()

Returns the number of elements in the container.

Returns:

The number of elements in the container.

Item

public FVector64<T> Item(long index)

Gets the element at the specified index.

Parameters:

index - The zero-based index of the element to get or set. The element at the specified index.

Returns:

The vector at the specified index.

Throws:

java.lang.RuntimeException - When the specified index is of [0, Size - 1] range.

Clear

public void Clear()

Removes all vectors from the parent container.
