Constructor Detail

BinaryWriteBuffer

public BinaryWriteBuffer(int cbCap)

Construct an BinaryWriteBuffer with a certain initial capacity.

Parameters:

cbCap - initial capacity

Throws:

java.lang.IllegalArgumentException - if cbCap is negative

BinaryWriteBuffer

public BinaryWriteBuffer(int cbCap,
                         int cbMax)

Construct an BinaryWriteBuffer with a certain initial capacity and a certain maximum capacity.

Parameters:

cbCap - initial capacity

cbMax - maximum capacity

Throws:

java.lang.IllegalArgumentException - if cbCap or cbMax is negative, or if cbCap is greater than cbMax

Method Detail

toBinary

public Binary toBinary()

Returns a new Binary object that holds the complete contents of this WriteBuffer.

This method is functionally equivalent to the following code:

 return getUnsafeReadBuffer().toBinary();
 

Specified by:

toBinary in interface WriteBuffer

Overrides:

toBinary in class ByteArrayWriteBuffer

Returns:

the contents of this WriteBuffer as a Binary object

checkBounds

protected void checkBounds(int of,
                           int cb)

Validate the ranges for the passed bounds and make sure that the underlying array is big enough to handle them.

Note: This method prevents all modifications from occurring once the BinaryWriteBuffer has supplied its byte array to a Binary object.

Overrides:

checkBounds in class ByteArrayWriteBuffer

Parameters:

of - the offset that data is about to be written to

cb - the length of the data that is about to be written
