Constructor Details

FloatMemoryArrayAccess

public FloatMemoryArrayAccess(float[] data,
 int offset,
 int length)

Create an array access.

Parameters:

data - The underlying array.

offset - The offset of the access segment within the array.

length - The access segment.

Method Details

subsequence

public ArrayAccess subsequence(int offset,
 int length)

Description copied from class: ArrayAccess

Create a sub-sequence view of this array access.

Note that the changes done to the sub-sequence array are not necessarily committed to the underlying data storage when the sub-sequence is closed (with ArrayAccess.close()), but only when the "base" ArrayAccess is closed.

Specified by:

subsequence in class ArrayAccess

Parameters:

offset - The sub-sequence starting offset within this ArrayAccess.

length - The sub-sequence length.

Returns:

The sub-sequence array access.

getData

public Object getData()

Description copied from class: ArrayAccess

Returns the array of this array access. This is an array of a primitive type, depending on the implementation class.

Specified by:

getData in class ArrayAccess

Returns:

The backing array of this array access.

getFloatData

public float[] getFloatData()

Description copied from class: ArrayAccess

Returns the array of this array access as a float[].

Overrides:

getFloatData in class ArrayAccess

Returns:

The backing array of this array access.

close

public void close()
           throws ApfloatRuntimeException

Description copied from class: ArrayAccess

Close this array access and commit any changes to the underlying data storage if applicable.

If the ArrayAccess was obtained in write mode, the changes are saved to the data storage. Note that even if the ArrayAccess was obtained for reading only, any changes made to the array data may still be committed to the data storage.

Note that changes done to a sub-sequence array are not necessarily committed to the underlying data storage when the sub-sequence is closed, but only when the "base" ArrayAccess is closed.

Specified by:

close in interface AutoCloseable

Specified by:

close in class ArrayAccess

Throws:

ApfloatRuntimeException
