Constructor Detail

ByteArrayStream

public ByteArrayStream()

ByteArrayStream

public ByteArrayStream(int size)

Parameters:

size - if accurate, toByteArray() will be zero-copy

Method Detail

reset

public void reset()

Overrides:

reset in class ByteArrayOutputStream

Throws:

IllegalStateException - if previously written

toByteArray

public byte[] toByteArray()

Zero-copy only if the data fills the buffer. Use asInputStream() for guaranteed zero-copy.

Overrides:

toByteArray in class ByteArrayOutputStream

asInputStream

public ByteArrayInputStream asInputStream()

All data previously written. Zero-copy. Not a Pipe. Data written after this call will not appear.

copyTo

public void copyTo(byte[] target,
                   int offset)

Copy all data to the target

verifySignature

public boolean verifySignature(Signature signature,
                               SigningPublicKey verifyingKey)

Verify the written data

verifySignature

public boolean verifySignature(I2PAppContext ctx,
                               Signature signature,
                               SigningPublicKey verifyingKey)

Verify the written data

sign

public Signature sign(SigningPrivateKey signingKey)

Sign the written data

Returns:

null on error

sign

public Signature sign(I2PAppContext ctx,
                      SigningPrivateKey signingKey)

Sign the written data

Returns:

null on error
