java.lang.Objectjava.io.OutputStream
er.extensions.foundation.ERXRefByteArrayOutputStream
public class ERXRefByteArrayOutputStream
This class is uh ... inspired ... by ByteArrayOutputStream, except that it gives direct access to the underlying byte buffer for performing operations on the buffer without a byte array copying penalty.
Field Summary | |
---|---|
protected byte[] |
buf
The buffer where data is stored. |
protected int |
count
The number of valid bytes in the buffer. |
Constructor Summary | |
---|---|
ERXRefByteArrayOutputStream()
Creates a new byte array output stream. |
|
ERXRefByteArrayOutputStream(int size)
Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes. |
Method Summary | |
---|---|
void |
close()
Closing a ByteArrayOutputStream has no effect. |
byte[] |
getBuffer()
Returns the underlying byte buffer for this stream. |
void |
reset()
Resets the count field of this byte array output
stream to zero, so that all currently accumulated output in the
ouput stream is discarded. |
int |
size()
Returns the current size of the buffer. |
byte[] |
toByteArray()
Creates a newly allocated byte array. |
com.webobjects.foundation.NSData |
toNSData()
Returns a no-copy NSData of the byte buffer for this stream. |
java.lang.String |
toString()
Converts the buffer's contents into a string, translating bytes into characters according to the platform's default character encoding. |
java.lang.String |
toString(int hibyte)
Deprecated. This method does not properly convert bytes into characters. As of JDK 1.1, the preferred way to do this is via the toString(String enc) method, which takes an encoding-name
argument, or the toString() method, which uses the
platform's default character encoding. |
java.lang.String |
toString(java.lang.String enc)
Converts the buffer's contents into a string, translating bytes into characters according to the specified character encoding. |
void |
write(byte[] b,
int off,
int len)
Writes len bytes from the specified byte array
starting at offset off to this byte array output stream. |
void |
write(int b)
Writes the specified byte to this byte array output stream. |
void |
writeTo(java.io.OutputStream out)
Writes the complete contents of this byte array output stream to the specified output stream argument, as if by calling the output stream's write method using out.write(buf, 0, count) . |
