Field Detail

flags

protected int flags

A flag mask that describes the boolean attributes enabled for this Buffer. This mask is set to the logical sum of all of the flags that are set.

See Also:

FLAG_IS_COPY

data

protected byte[] data

The byte array that actually holds the media data chunk for this Buffer.

length

protected int length

States how many samples are valid in the array. (The array itself might be larger than the length).

offset

protected int offset

Points to the starting point (offset) into the array where the valid data begins.

FLAG_IS_COPY

public static final int FLAG_IS_COPY

Indicates that this data is a copy or clone and changing it will not affect the data it was generated from.

Method Detail

getFlags

public int getFlags()

Gets the mask of the flags set for this Buffer. The integer value of the mask is equal to the logical sum of the flags that are set.

Returns:

the currently active flags

See Also:

FLAG_IS_COPY, setFlags(int)

setFlags

public void setFlags(int flags)

Sets the flag mask for this Buffer. The integer value of the mask is equal to the logical sum of the flags that are set.

Parameters:

flags - The specific flags to be set for the buffer object

See Also:

FLAG_IS_COPY, getFlags()

getData

public byte[] getData()

Gets the internal byte array for this Buffer.

Returns:

The byte array for this Buffer.

See Also:

data, setData(byte[])

setData

public void setData(byte[] data)

Sets the internal byte array for this Buffer.

Parameters:

data - the byte array to be set

See Also:

data, getData()

getLength

public int getLength()

Gets the length of the valid data in this Buffer.

Returns:

The length of the valid data in the data byte array. for this Buffer.

See Also:

length, setLength(int)

setLength

public void setLength(int length)

Sets the length of the valid data in this Buffer.

Parameters:

length - The length of the valid data in the data byte array.

See Also:

length, getLength()

getOffset

public int getOffset()

Gets the offset of the valid data in this Buffer.

Returns:

The starting point of the valid data in the data byte array.

See Also:

offset, setOffset(int)

setOffset

public void setOffset(int offset)

Parameters:

offset - The starting point of the valid data in the data byte array.

See Also:

offset, getOffset()

copy

public void copy(DataSectionDataBuffer buffer)

Copy the attributes from the specified Buffer into this Buffer.

Parameters:

buffer - The input Buffer the copy the attributes from.

copy

public void copy(DataSectionDataBuffer buffer,
                 boolean swapData)

Copy the attributes from the specified Buffer into this Buffer. If swapData is true, the data values are swapped between the buffers, otherwise the data value is copied.

Parameters:

buffer - The input Buffer the copy the attributes from.

swapData - Specifies whether the data objects are to be swapped.

clone

public Object clone()

Clone a buffer.

Returns:

the cloned object

toString

public String toString()

The String representation of the object.

Returns:

the string representation
