encode	back to summary
public boolean encode(CharBuffer src, ByteBuffer dest, Agent agent) throws SqlException Implements abstract org.apache.derby.client.net.CcsidManager.encode. Doc from org.apache.derby.client.net.CcsidManager.encode. Encode the contents of a `CharBuffer` into a `ByteBuffer`. The method will return `true` if all the characters were encoded and copied to the destination. If the receiving byte buffer is too small to hold the entire encoded representation of the character buffer, the method will return `false`. The caller should then allocate a larger byte buffer, copy the contents from the old byte buffer to the new one, and then call this method again to get the remaining characters encoded. Parameters src:CharBuffer buffer holding the characters to encode dest:ByteBuffer buffer receiving the encoded bytes agent:Agent where to report errors Returns:boolean `true` if all characters were encoded, `false` if the destination buffer is full and there still are more characters to encode Exceptions SqlException: if the characters cannot be encoded using this CCSID manager's character encoding

public boolean encode(CharBuffer src, ByteBuffer dest, Agent agent) throws SqlException

Implements abstract org.apache.derby.client.net.CcsidManager.encode.

Doc from org.apache.derby.client.net.CcsidManager.encode.

Encode the contents of a CharBuffer into a ByteBuffer. The method will return true if all the characters were encoded and copied to the destination. If the receiving byte buffer is too small to hold the entire encoded representation of the character buffer, the method will return false. The caller should then allocate a larger byte buffer, copy the contents from the old byte buffer to the new one, and then call this method again to get the remaining characters encoded.

Parameters

src:CharBuffer: buffer holding the characters to encode
dest:ByteBuffer: buffer receiving the encoded bytes
agent:Agent: where to report errors

Returns:boolean

true if all characters were encoded, false if the destination buffer is full and there still are more characters to encode

Exceptions

SqlException:: if the characters cannot be encoded using this CCSID manager's character encoding

startEncoding back to summary

startEncoding	back to summary
public void startEncoding() Implements abstract org.apache.derby.client.net.CcsidManager.startEncoding. Doc from org.apache.derby.client.net.CcsidManager.startEncoding. Initialize this instance for encoding a new string. This method resets any internal state that may be left after earlier calls to `encode` on this instance. For example, it may reset the internal `java.nio.charset.CharsetEncoder`, if the implementation uses one to do the encoding.

public void startEncoding()

Implements abstract org.apache.derby.client.net.CcsidManager.startEncoding.

Doc from org.apache.derby.client.net.CcsidManager.startEncoding.

Initialize this instance for encoding a new string. This method resets any internal state that may be left after earlier calls to encode on this instance. For example, it may reset the internal java.nio.charset.CharsetEncoder, if the implementation uses one to do the encoding.
