- Method Detail
  - toString
```
public static String toString(Object value)
```
    Returns string representation of an object, including Clob. For large CLOBs, be careful because this will load an entire CLOB in memory as java.lang.String.
    
    Parameters:
    value - value to convert.
    
    Returns:
    string representation of an object, including Clob.
  - toBoolean
```
public static Boolean toBoolean(Object value)
```
    Returns true if the value is any numeric type and has a value of 1, or if string type has a value of '1', 't', 'y', 'true' or 'yes'. Otherwise, return false.
    
    Parameters:
    value - value to convert
    
    Returns:
    true if the value is any numeric type and has a value of 1, or if string type has a value of '1', 't', 'y', 'true' or 'yes'. Otherwise, return false.
  - toSqlDate
```
public static Date toSqlDate(Object value)
```
    Expects a java.sql.Date, java.sql.Timestamp, java.sql.Time, java.util.Date, Long or any object whose toString method has this format: yyyy-mm-dd.
    
    Parameters:
    value - argument that is possible to convert to java.sql.Date.
    
    Returns:
    java.sql.Date instance representing input value.
  - truncateToSqlDate
```
public static Date truncateToSqlDate(Object value)
```
    Expects a java.sql.Date, java.sql.Timestamp, java.sql.Time, java.util.Date, Long or string with format "yyyy-MM-dd". This method will truncate hours, minutes, seconds and milliseconds to zeros, to conform with JDBC spec: http://download.oracle.com/javase/6/docs/api/java/sql/Date.html.
    This method is tread-safe.
    
    Parameters:
    value - argument that is possible to convert to java.sql.Date: java.sql.Date, java.sql.Timestamp, java.sql.Time, java.util.Date, Long or any object with toString() == yyyy-mm-dd.
    
    Returns:
    java.sql.Date instance representing input value.
  - truncateToSqlDate
```
public static Date truncateToSqlDate(long time)
```
    This method will truncate hours, minutes, seconds and milliseconds to zeros, to conform with JDBC spec: http://download.oracle.com/javase/6/docs/api/java/sql/Date.html.
    
    Parameters:
    time - time in UTC milliseconds from the epoch
    
    Returns:
    java.sql.Date instance representing time value
  - toIsoString
```
public static String toIsoString(Date date)
```
    Converts a java.util.Date to a String in ISO 8601 format: "yyyy-MM-dd'T'HH:mm:ss'Z'" in UTC timezone for timestamps, and "yyyy-MM-dd" for instances of java.sql.Date.
    This method is tread-safe.
    
    Parameters:
    date - date to convert
    
    Returns:
    String in ISO 8601 format
  - toDouble
```

  - toTime
```
public static Time toTime(Object value)
```
    If the value is instance of java.sql.Time, returns it, else tries to convert java.util.Date or Long to Time, else tries to convert using Time.valueOf(String). This method might trow IllegalArgumentException if fails at conversion.

    value - value to be converted.
    
    Returns:
    value converted to byte array.
  - toBytes
