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

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
