Constructor Detail

ByteVectorback to summary
public ByteVector()

Constructs a new ByteVector with a default initial capacity.

ByteVectorback to summary
public ByteVector(final int initialCapacity)

Constructs a new ByteVector with the given initial capacity.

Parameters
initialCapacity:int

the initial capacity of the byte vector to be constructed.

ByteVectorback to summary
pack-priv ByteVector(final byte[] data)

Constructs a new ByteVector from the given initial data.

Parameters
data:byte[]

Method Detail

encodeUtf8back to summary
pack-priv final ByteVector encodeUtf8(final String stringValue, final int offset, final int maxByteLength)

Puts an UTF8 string into this byte vector. The byte vector is automatically enlarged if necessary. The string length is encoded in two bytes before the encoded characters, if there is space for that (i.e. if this.length - offset - 2 >= 0).

Parameters
stringValue:String

the String to encode.

offset:int

the index of the first character to encode. The previous characters are supposed to have already been encoded, using only one byte per character.

maxByteLength:int

the maximum byte length of the encoded string, including the already encoded characters.

Returns:ByteVector

this byte vector.

enlargeback to summary
private void enlarge(final int size)

Enlarges this byte vector so that it can receive 'size' more bytes.

Parameters
size:int

number of additional bytes that this byte vector should be able to receive.

put11back to summary
pack-priv final ByteVector put11(final int byteValue1, final int byteValue2)

a byte.

byteValue2:int

another byte.

Returns:ByteVector

this byte vector.

put112back to summary
pack-priv final ByteVector put112(final int byteValue1, final int byteValue2, final int shortValue)
