                      int allocationSize)

Method Detail

_setAllocationSize

protected void _setAllocationSize(int allocationSizeSuggestion)

length

public abstract int length()

Get the length of the data in the buffer

Returns:

the length of the data

capacity

public abstract int capacity()

Get the number of bytes currently allocated (available) without resizing

Returns:

the number of bytes

equals

public abstract boolean equals(byte[] bytes)

Determine if a byte array contains the same bytes as this builder

Parameters:

bytes - the bytes

Returns:

true if the supplied value equals what is in the builder

toByteArray

public abstract byte[] toByteArray()

Copy the value in the buffer to a new byte array

Returns:

the copy of the bytes

internalArray

public abstract byte[] internalArray()

Access the internal byte array of this buffer. Intended for read only with knowledge of length()

Returns:

a direct handle to the internal byte array

appendUnchecked

public abstract int appendUnchecked(byte b)

Append a single byte without checking that the builder has the capacity

Parameters:

b - the byte

Returns:

the number of bytes appended, always 1

appendUnchecked

public abstract int appendUnchecked(byte[] src)

Append the entire byte array without checking that the builder has the capacity

Parameters:

src - the source byte array

Returns:

the number of bytes appended

appendUnchecked

public abstract int appendUnchecked(byte[] src,
                                    int srcPos,
                                    int len)

Append the entire byte array without checking that the builder has the capacity

Parameters:

src - the source byte array

srcPos - starting position in the source array.

len - the number of array elements to be copied.

Returns:

the number of bytes appended

getAllocationSize

public int getAllocationSize()

Get the current allocation size

Returns:

the allocation size

bufferAllocSize

public static int bufferAllocSize(int atLeast,
                                  int blockSize)
