Class ByteVector

java.lang.Object

mockit.asm.util.ByteVector

public final class ByteVector
extends Object

A dynamically extensible vector of bytes. This class is roughly equivalent to a DataOutputStream on top of a ByteArrayOutputStream, but is more efficient.

Constructor Details

ByteVector

public ByteVector()

Constructs a new ByteVector with a default initial size.

ByteVector

public ByteVector(@NonNegative int initialSize)

Constructs a new ByteVector with the given initial size.

Method Details

getData

@NonNull
public byte[] getData()

Returns the byte data.

getLength

public @NonNegative int getLength()

Returns the length of this vector, in bytes.

setLength

public void setLength(@NonNegative int length)

Sets the length of this vector, in bytes.

putByte

@NonNull
public ByteVector putByte(int b)

Puts a byte into this byte vector. The byte vector is automatically enlarged if necessary.

Returns:

this byte vector

put11

@NonNull
public ByteVector put11(int b1,
 int b2)

Puts two bytes into this byte vector. The byte vector is automatically enlarged if necessary.

Returns:

this byte vector

putShort

@NonNull
public ByteVector putShort(int s)

Puts a short into this byte vector. The byte vector is automatically enlarged if necessary.

Returns:

this byte vector

put12

@NonNull
public ByteVector put12(int b,
 int s)

Puts a byte and a short into this byte vector. The byte vector is automatically enlarged if necessary.

Returns:

this byte vector

putInt

@NonNull
public ByteVector putInt(int i)

Puts an int into this byte vector. The byte vector is automatically enlarged if necessary.

Returns:

this byte vector

putLong

public void putLong(long l)

Puts a long into this byte vector. The byte vector is automatically enlarged if necessary.

putUTF8

public void putUTF8(@NonNull
 String utf8String)

Puts an UTF8 string into this byte vector. The byte vector is automatically enlarged if necessary.

Parameters:

utf8String - a String whose UTF8 encoded length must be less than 65536

putByteArray

public void putByteArray(@NonNull
 byte[] bytes,
 @NonNegative int offset,
 @NonNegative int numBytes)

Puts an array of bytes into this byte vector. The byte vector is automatically enlarged if necessary.

Parameters:

bytes - an array of bytes

offset - index of the first byte of code that must be copied

numBytes - number of bytes of code that must be copied

putByteVector

public void putByteVector(@NonNull
 ByteVector another)

roundUpLength

public void roundUpLength()
