Methods Summary
public java.sql.Array	readArray() Reads an SQL ARRAY value from the stream and returns it as an Array object in the Java programming language. return an Array object representing data of the SQL ARRAY value at the head of the stream; null if the value read is SQL NULL exception SQLException if a database access error occurs
public java.io.InputStream	readAsciiStream() Reads the next attribute in the stream and returns it as a stream of ASCII characters. return the attribute; if the value is SQL NULL, returns null exception SQLException if a database access error occurs
public java.math.BigDecimal	readBigDecimal() Reads the next attribute in the stream and returns it as a java.math.BigDecimal object in the Java programming language. return the attribute; if the value is SQL NULL, returns null exception SQLException if a database access error occurs
public java.io.InputStream	readBinaryStream() Reads the next attribute in the stream and returns it as a stream of uninterpreted bytes. return the attribute; if the value is SQL NULL, returns null exception SQLException if a database access error occurs
public java.sql.Blob	readBlob() Reads an SQL BLOB value from the stream and returns it as a Blob object in the Java programming language. return a Blob object representing data of the SQL BLOB value at the head of the stream; null if the value read is SQL NULL exception SQLException if a database access error occurs
public boolean	readBoolean() Reads the next attribute in the stream and returns it as a boolean in the Java programming language. return the attribute; if the value is SQL NULL, returns false exception SQLException if a database access error occurs
public byte	readByte() Reads the next attribute in the stream and returns it as a byte in the Java programming language. return the attribute; if the value is SQL NULL, returns 0 exception SQLException if a database access error occurs
public byte[]	readBytes() Reads the next attribute in the stream and returns it as an array of bytes in the Java programming language. return the attribute; if the value is SQL NULL, returns null exception SQLException if a database access error occurs
public java.io.Reader	readCharacterStream() Reads the next attribute in the stream and returns it as a stream of Unicode characters. return the attribute; if the value is SQL NULL, returns null exception SQLException if a database access error occurs
public java.sql.Clob	readClob() Reads an SQL CLOB value from the stream and returns it as a Clob object in the Java programming language. return a Clob object representing data of the SQL CLOB value at the head of the stream; null if the value read is SQL NULL exception SQLException if a database access error occurs
public java.sql.Date	readDate() Reads the next attribute in the stream and returns it as a java.sql.Date object. return the attribute; if the value is SQL NULL, returns null exception SQLException if a database access error occurs
public double	readDouble() Reads the next attribute in the stream and returns it as a double in the Java programming language. return the attribute; if the value is SQL NULL, returns 0 exception SQLException if a database access error occurs
public float	readFloat() Reads the next attribute in the stream and returns it as a float in the Java programming language. return the attribute; if the value is SQL NULL, returns 0 exception SQLException if a database access error occurs
public int	readInt() Reads the next attribute in the stream and returns it as an int in the Java programming language. return the attribute; if the value is SQL NULL, returns 0 exception SQLException if a database access error occurs
public long	readLong() Reads the next attribute in the stream and returns it as a long in the Java programming language. return the attribute; if the value is SQL NULL, returns 0 exception SQLException if a database access error occurs
public java.lang.Object	readObject() Reads the datum at the head of the stream and returns it as an Object in the Java programming language. The actual type of the object returned is determined by the default type mapping, and any customizations present in this stream's type map. A type map is registered with the stream by the JDBC driver before the stream is passed to the application. When the datum at the head of the stream is an SQL NULL, the method returns null. If the datum is an SQL structured or distinct type, it determines the SQL type of the datum at the head of the stream. If the stream's type map has an entry for that SQL type, the driver constructs an object of the appropriate class and calls the method SQLData.readSQL on that object, which reads additional data from the stream, using the protocol described for that method. return the datum at the head of the stream as an Object in the Java programming language;null if the datum is SQL NULL exception SQLException if a database access error occurs
public java.sql.Ref	readRef() Reads an SQL REF value from the stream and returns it as a Ref object in the Java programming language. return a Ref object representing the SQL REF value at the head of the stream; null if the value read is SQL NULL exception SQLException if a database access error occurs
public short	readShort() Reads the next attribute in the stream and returns it as a short in the Java programming language. return the attribute; if the value is SQL NULL, returns 0 exception SQLException if a database access error occurs
public java.lang.String	readString() Reads the next attribute in the stream and returns it as a String in the Java programming language. return the attribute; if the value is SQL NULL, returns null exception SQLException if a database access error occurs
public java.sql.Time	readTime() Reads the next attribute in the stream and returns it as a java.sql.Time object. return the attribute; if the value is SQL NULL, returns null exception SQLException if a database access error occurs
public java.sql.Timestamp	readTimestamp() Reads the next attribute in the stream and returns it as a java.sql.Timestamp object. return the attribute; if the value is SQL NULL, returns null exception SQLException if a database access error occurs
public java.net.URL	readURL() Reads an SQL DATALINK value from the stream and returns it as a java.net.URL object in the Java programming language. return a java.net.URL object. exception SQLException if a database access error occurs, or if a URL is malformed since 1.4
public boolean	wasNull() Retrieves whether the last value read was SQL NULL. return true if the most recently read SQL value was SQL NULL; false otherwise exception SQLException if a database access error occurs
